[PATCH 0/4] musb fixes for v4.9-rc cycle

[Tony Lindgren]

Hi all,

Here are musb fixes for the issues that I've been able to track down.
Not sure if these will help with the problem Ladis was seeing as I'm
not able to reproduce that one it seems.

As many people depend on this driver I'd like to have these merged
for v4.9-rc cycle after review and testing.

Please review and test. You need to use v4.9-rc3 or later for testing
because of the earlier fixes.

Regards,

Tony

[PATCH 1/4] usb: musb: Fix broken use of static variable for multiple instances

[Tony Lindgren]

We can't use static variable first for checking when musb is
initialized when we have multiple musb instances like on am335x.

[PATCH 2/4] usb: musb: Fix sleeping function called from invalid context for hdrc glue

[Tony Lindgren]

Commit 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer") wrongly added a call for pm_runtime_get_sync to otg_timer
that runs in softirq context. That causes a "BUG: sleeping function called
from invalid context" every time when polling the cable status:

[<c015ebb4>] (__might_sleep) from [<c0413d60>] (__pm_runtime_resume+0x9c/0xa0)
[<c0413d60>] (__pm_runtime_resume) from [<c04d0bc4>] (otg_timer+0x3c/0x254)
[<c04d0bc4>] (otg_timer) from [<c0191180>] (call_timer_fn+0xfc/0x41c)
[<c0191180>] (call_timer_fn) from [<c01915c0>] (expire_timers+0x120/0x210)
[<c01915c0>] (expire_timers) from [<c0191acc>] (run_timer_softirq+0xa4/0xdc)
[<c0191acc>] (run_timer_softirq) from [<c010168c>] (__do_softirq+0x12c/0x594)

I did not notice that as I did not have CONFIG_DEBUG_ATOMIC_SLEEP enabled.
And looks like also musb_gadget_queue() suffers from the same problem.

Let's fix the issue by using a list of delayed work then call it on
resume. Note that we want to do this only when musb core and it's
parent devices are awake as noted by Johan Hovold <johan-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>.

Also note that we now also need to get rid of static int first as
that won't work right on devices with two musb instances like am335x.

Later on we may be able to remove other delayed work in the musb driver
and just do it from pending_resume_work. But this should be done only
for delayed work that does not have other timing requirements beyond
just being run on resume.

Fixes: 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer")

This construct is no longer needed as no work is (and must not be) added
while the controller is resumed and list_for_each_entry_safe() would
therefore do.

The interactions with system suspend looks a bit suspicious. It seems
you need to drain any pending resume work on suspend for example.

And then the above should not be needed, right?

In fact, the dsps timer must also be cancelled on suspend, or you could
end up calling dsps_check_status() while suspended (it is currently not
cancelled until the parent device is suspended, which could be too
late).

Hmm that's an interesting idea. I think that would allow us to get
rid of the delayed work if we check the list both on resume and
suspend :)

And then this should no longer be an issue either.

I'll take a look and will also check the other comments.

Tony

Note that I was referring to draining the runtime-resume work on system
suspend above. I think we still want the delayed work considering that
we could stay active for long periods of time.

It would still be an issue as a system-suspending device could already
have been runtime-resumed so that dsps_check_status() would be called
directly from the timer function.

It seems it's the delayed work causing these race issues, so I'd like
to avoid it. I think we can do it all from PM runtime resume and
checking at the end of musb_queue_resume_work(). We need to introduce
is_runtime_suspended though. This is along the lines of what we have
in Documentation/power/runtime_pm.txt if you search for completion
there.

Below is a version doing things without delayed work, care to check
again if you still see races there?

The glue layers should do pm_runtime_get_sync(musb->controller) which
dsps glue already does. So that's the musb_core.c device instance. And
looks like we have dsps_suspend() call del_timer_sync(&glue->timer)
already. I think we're safe here.

Tony

Subject: [PATCH] usb: musb: Fix sleeping function called from invalid
 context for hdrc glue

Commit 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer") wrongly added a call for pm_runtime_get_sync to otg_timer
that runs in softirq context. That causes a "BUG: sleeping function called
from invalid context" every time when polling the cable status:

[<c015ebb4>] (__might_sleep) from [<c0413d60>] (__pm_runtime_resume+0x9c/0xa0)
[<c0413d60>] (__pm_runtime_resume) from [<c04d0bc4>] (otg_timer+0x3c/0x254)
[<c04d0bc4>] (otg_timer) from [<c0191180>] (call_timer_fn+0xfc/0x41c)
[<c0191180>] (call_timer_fn) from [<c01915c0>] (expire_timers+0x120/0x210)
[<c01915c0>] (expire_timers) from [<c0191acc>] (run_timer_softirq+0xa4/0xdc)
[<c0191acc>] (run_timer_softirq) from [<c010168c>] (__do_softirq+0x12c/0x594)

I did not notice that as I did not have CONFIG_DEBUG_ATOMIC_SLEEP enabled.
And looks like also musb_gadget_queue() suffers from the same problem.

Let's fix the issue by using a list of delayed work then call it on
resume. Note that we want to do this only when musb core and it's
parent devices are awake as noted by Johan Hovold <johan-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>.

Later on we may be able to remove other delayed work in the musb driver
and just do it from pending_resume_work. But this should be done only
for delayed work that does not have other timing requirements beyond
just being run on resume.

Fixes: 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer")

Hmm I think we can also leave out musb_run_resume_work() at the end,
we should not hit that case any longer.

That seems to be the case, yes. But we still need to process that work
somehow also when racing with runtime_resume() (e.g. here or at every
call site).

Sure, if you can avoid processing the deferred work also at
runtime-suspend then getting rid of the delayed work would be preferred.

I believe there are still some issues however.

But the point is that the controller might be RPM_ACTIVE if the
controller was already runtime resumed when it is system suspended.

Since this (and the previous) patch run the work directly from the timer
callback if active, it could end up accessing the controller after it
has been system suspended. Specifically, stopping the timer in the glue
(parent) suspend callback is too late to avoid this.

	pm_runtime_get_sync(musb->controller);
		musb_runtime_resume()
			musb_restore_context();
	
	...

	musb_suspend()
		musb_save_context();

	otg_timer()
		pm_runtime_get();
		if (pm_runtime_active(musb->controller))
			dsps_check_status();
		pm_runtime_put_autosuspend();

	dsps_suspend()
		del_timer_sync();

But this means you should be able to run the callback below, right? It
has to be run from somewhere so otherwise the caller needs to retry
instead.

And this also depends on anyone attempting to queue work having first
gotten an RPM reference (so that driver core runtime resumes the device
before calling suspend()).

But no, there's actually still a window were this could be false when
work is queued while runtime resuming (and eventually is executed from
musb_queue_resume_work()).

This does not seem to hold as work could get queued while RPM_SUSPENDING
unless you also take the list_lock here (or add explicit barriers).

As you just pointed out that can actually never happen and corresponding
code can be removed from musb_queue_resume_work(), so scrap this last
paragraph too. :)

OK so we need to return without doing anything from otg_timer() on
pm_runtime_get() to avoid that.

In the long run it would be nice to make whatever optional state polling
musb generic with just a glue layer callback.

Good point, will add.

Well there's no longer need to run the callback at that point any longer
and with that removed that should not be an issue.

Anyways, musb->is_runtime_suspended is needed to protect anything from
being queued between runtime resume having called musb_run_resume_work()
and before pm_runtime_active() is true. At that point the caller could
just wait for pm_runtime_active() to be set and run the code. But based
on my tests that does not happen and queueing is faster than getting to
the pm_runtime_active() state so we just print errors in those cases if
we ever hit it later on.

Sounds like the rest of your comments are no longer an issue, please
let me know if that's not the case.

Updated version n of the patch below.

Regards,

Tony

Subject: [PATCH] usb: musb: Fix sleeping function called from invalid
 context for hdrc glue

Commit 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer") wrongly added a call for pm_runtime_get_sync to otg_timer
that runs in softirq context. That causes a "BUG: sleeping function called
from invalid context" every time when polling the cable status:

[<c015ebb4>] (__might_sleep) from [<c0413d60>] (__pm_runtime_resume+0x9c/0xa0)
[<c0413d60>] (__pm_runtime_resume) from [<c04d0bc4>] (otg_timer+0x3c/0x254)
[<c04d0bc4>] (otg_timer) from [<c0191180>] (call_timer_fn+0xfc/0x41c)
[<c0191180>] (call_timer_fn) from [<c01915c0>] (expire_timers+0x120/0x210)
[<c01915c0>] (expire_timers) from [<c0191acc>] (run_timer_softirq+0xa4/0xdc)
[<c0191acc>] (run_timer_softirq) from [<c010168c>] (__do_softirq+0x12c/0x594)

I did not notice that as I did not have CONFIG_DEBUG_ATOMIC_SLEEP enabled.
And looks like also musb_gadget_queue() suffers from the same problem.

Let's fix the issue by using a list of delayed work then call it on
resume. Note that we want to do this only when musb core and it's
parent devices are awake as noted by Johan Hovold <johan-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>.

Later on we may be able to remove other delayed work in the musb driver
and just do it from pending_resume_work. But this should be done only
for delayed work that does not have other timing requirements beyond
just being run on resume.

glue layer")

I'm afraid that won't work as pm_runtime_get() would still succeed (i.e.
even after musb_suspend()).

See 6f3c77b040fc ("PM / Runtime: let rpm_resume() succeed if RPM_ACTIVE,
even when disabled, v2").

Yes, and make sure to stop polling in musb_suspend(). Would it be
possible to use the enable and disable ops for this until then?

But for a generic solution, this race could still be an issue. What
about musb_gadget_queue() for example? Would not failing to start I/O
if racing with resume be a problem?

I think the barrier comment for the WARN_ON on musb_runtime_suspend()
still applies.

Isn't the compiler free to reorder the store to is_runtime_suspended
here so that the WARN_ON could trigger when queuing is racing with
runtime suspend?

Removing the WARN_ON, or moving it under list_lock while updating
is_runtime_suspended should do.

So as mentioned above, this would not be sufficient to detect that dev
has been (system) suspended.

But doesn't that assume that we have musb core as in musb->controller
in RPM_ACTIVE state? While if it's been suspended that's not the
case meaning rpm_resume would fail?

If we have a window for a race there with RPM_ACTIVE set, we could
add musb->is_disabled flag that gets set in musb_suspend().

Hmm care to explain a bit more? That is assuming that rpm_resume()
won't fail above.. And that using musb->is_disabled flag won't
work..

It's probably safest to return an error for cases like that rather
than attempt to do something and risk corrupting packets. I'll move
the check to happen earlier musb_gadget_queue() so we don't do
anything with the request if pm_runtime_get() fails there. That
should make it easy to add further handling if we ever start really
hitting that issue.

Will do and move it earlier to bail out before doing anything
with the request.

Oh you're talking about musb_enable/disable ops, not the
pm_runtime/enable/disable ops :)

Yeah that might work for disabling the dsps specific timer.

Right, and it's still a good idea to check the return value of
pm_runtime_get(). It just won't be enough for when RPM_ACTIVE.

By stopping the timer in musb->ops->disable which is called during
suspend, the race could perhaps also be avoided.

Subject: [PATCH] usb: musb: Fix sleeping function called from invalid
 context for hdrc glue

Commit 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer") wrongly added a call for pm_runtime_get_sync to otg_timer
that runs in softirq context. That causes a "BUG: sleeping function called
from invalid context" every time when polling the cable status:

[<c015ebb4>] (__might_sleep) from [<c0413d60>] (__pm_runtime_resume+0x9c/0xa0)
[<c0413d60>] (__pm_runtime_resume) from [<c04d0bc4>] (otg_timer+0x3c/0x254)
[<c04d0bc4>] (otg_timer) from [<c0191180>] (call_timer_fn+0xfc/0x41c)
[<c0191180>] (call_timer_fn) from [<c01915c0>] (expire_timers+0x120/0x210)
[<c01915c0>] (expire_timers) from [<c0191acc>] (run_timer_softirq+0xa4/0xdc)
[<c0191acc>] (run_timer_softirq) from [<c010168c>] (__do_softirq+0x12c/0x594)

I did not notice that as I did not have CONFIG_DEBUG_ATOMIC_SLEEP enabled.
And looks like also musb_gadget_queue() suffers from the same problem.

Let's fix the issue by using a list of delayed work then call it on
resume. Note that we want to do this only when musb core and it's
parent devices are awake, and we need to make sure the DSPS glue
timer is stopped as noted by Johan Hovold <johan-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>.

Later on we may be able to remove other delayed work in the musb driver
and just do it from pending_resume_work. But this should be done only
for delayed work that does not have other timing requirements beyond
just being run on resume.

Add pm_runtime_put_noidle() to balance the counter also on errors.

Missing pm_runtime_put_noidle() here too.

Indeed thanks for catching that.

Looks like we already have mod_timer() being called in dsps_musb_enable(),
I'll mention that in the patch description.

Right.. We're now returning early, adding it to both places.

Updated patch below.

Subject: [PATCH] usb: musb: Fix sleeping function called from invalid
 context for hdrc glue

Commit 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer") wrongly added a call for pm_runtime_get_sync to otg_timer
that runs in softirq context. That causes a "BUG: sleeping function called
from invalid context" every time when polling the cable status:

[<c015ebb4>] (__might_sleep) from [<c0413d60>] (__pm_runtime_resume+0x9c/0xa0)
[<c0413d60>] (__pm_runtime_resume) from [<c04d0bc4>] (otg_timer+0x3c/0x254)
[<c04d0bc4>] (otg_timer) from [<c0191180>] (call_timer_fn+0xfc/0x41c)
[<c0191180>] (call_timer_fn) from [<c01915c0>] (expire_timers+0x120/0x210)
[<c01915c0>] (expire_timers) from [<c0191acc>] (run_timer_softirq+0xa4/0xdc)
[<c0191acc>] (run_timer_softirq) from [<c010168c>] (__do_softirq+0x12c/0x594)

I did not notice that as I did not have CONFIG_DEBUG_ATOMIC_SLEEP enabled.
And looks like also musb_gadget_queue() suffers from the same problem.

Let's fix the issue by using a list of delayed work then call it on
resume. Note that we want to do this only when musb core and it's
parent devices are awake, and we need to make sure the DSPS glue
timer is stopped as noted by Johan Hovold <johan-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>.
Note that we already are re-enabling the timer with mod_timer() in
dsps_musb_enable().

Later on we may be able to remove other delayed work in the musb driver
and just do it from pending_resume_work. But this should be done only
for delayed work that does not have other timing requirements beyond
just being run on resume.

Fixes: 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer")

[PATCH 3/4] usb: musb: Fix PM for hub disconnect

[Tony Lindgren]

With a USB hub disconnected, devctl can be 0x19 for about a second
on am335x and will stay forever on at least omap3. And we get no
further interrupts when devctl session bit clears. This keeps
PM runtime active.

Let's fix the issue by polling devctl until the session bit clears
or times out. We can do this by making musb->irq_work into
delayed_work.

And with the polling implemented, we can now also have the quirk
for invalid VBUS it to avoid disconnecting too early while VBUS
is ramping up.

PM for musb-core")

[PATCH 4/4] phy: twl4030-usb: Fix for musb session bit based PM

[Tony Lindgren]

Now with musb driver implementing generic session bit based
PM, we need to have the USB PHYs behaving in a sane way for
platforms implementing PM.

Currently twl4030-usb enables PM in twl4030_phy_power_on()
and then disables it in twl4030_phy_power_off(). This will
block PM runtime for the SoC when no cable is connected.

Fix the issue by moving PM runtime autosuspend call to
happen where it gets called in twl4030_phy_power_on().

Note that this patch should not be backported to anything
before commit 467d5c980709 ("usb: musb: Implement session bit
based runtime PM for musb-core") as before that all the
glue layers implemented their own PM.

Fixes: 467d5c980709 ("usb: musb: Implement session bit based
runtime PM for musb-core")

Weird, I have not figured out what happens there..

The only thing I'm still wondering about is if phy-twl4030-usb.c
is losing ID pin interrupts occasionally but have not been
able to verify that. Maybe try the following additional patch
and see if it makes any difference?

And eventually the glue layers only should need to do this on
init:

pm_runtime_enable(glue->dev);

And this on the exit path:

pm_runtime_disable(glue->dev);

And musb core as the child device should keep things awake
when needed.

Tested your patch, does not work, does not trigger "USB link status err"
both without and with pm_runtime_enable/disable.

OK. The patch below still works for me with musb_core.c
autosuspend_delay set to 100. Also works with it set to 10.

Note that we had two timeouts without this.. Can you try
playing with the timeout in musb_core.c and see if that
helps?

Tony

This patch works for me, also with autosuspend_delay set to 10.

Oh so to confirm, the $subject series patches + this one only fixes
your issue? So no more revert needed?

I think the musb_core timeout had to be 500 to idle the 2430 glue
layer phy also, but I need to recheck that. That should be a
separate patch and can be done later.

Tony

Right. Revert is no more needed.

The series fixes my problems, both with the original and latest version of
patch 2/4.

I have however seen the following warning once with the original version of 2/4.

I've seen similar with interconnect target was not ready in time
on ti81xx when booting that got fixed with commit ebf244148092
("ARM: OMAP2+: Use srst_udelay for USB on dm814x"). It is possible
that omap4 needs similar fix but hard to say unless we have it
reproducable. Anyways, below is an untested patch for omap4 to play
with. Maybe repeated reboot or modprobe test would make it
reproducable?

Tony

I'll try to give it a go, but right now I'm stuck with a different MUSB 
problem :-) I'm trying to boot my panda board over the SMSC95xx ethernet, and 
have switched gadget support from being compiled in to being compiled as a 
module. I then get

[    2.766174] musb_bus_suspend 2586: trying to suspend as a_idle while active

printed in a loop at boot time. I've traced musb->is_active being set to 1 in 
musb_start() with 

musb->port_mode = MUSB_PORT_MODE_DUAL_ROLE
musb->xceiv->otg->state = OTG_STATE_A_IDLE
devctl = MUSB_DEVCTL_BDEVICE | MUSB_DEVCTL_VBUS

I can disable gadget support completely which will I believe fix the problem, 
but that's just a workaround. Help would be appreciated.

And on a side note, selecting CONFIG_USB_GADGET=m makes it impossible to build 
CONFIG_USB_NOT_XCEIV=y, making OMAP3 EHCI support only available as a module. 
*sigh* :-)

Felipe, git blame points at you, can this be fixed ?

Turns out it doesn't :-(

CONFIG_USB_MUSB_HDRC=y
CONFIG_USB_MUSB_HOST=y
# CONFIG_USB_GADGET is not set

and the problem still occurs.

Do you have the ID pin grounded or how do you get to the
A_IDLE state? I'm pretty much only testing with loadable
modules as in omap2plus_defconfig, I don't think I've seen
this issue..

Maybe check the changes in your .config against just plain
omap2plus_defconfig? Are you trying to force host only mode?

I've measured it on the board and I don't. Booting with the USB cable 
unplugged and the board powered through the power jack gives the same result.

Don't ask me :-)

I started anew from omap2plus_defconfig and applied the following changes to 
enable NFS root.

-CONFIG_USB_NET_DRIVERS=m
-CONFIG_USB_USBNET=m
-CONFIG_USB_NET_SMSC95XX=m
-CONFIG_USB=m
-CONFIG_USB_EHCI_HCD=m
-CONFIG_USB_EHCI_HCD_OMAP=m
-CONFIG_NOP_USB_XCEIV=m
-CONFIG_USB_GADGET=m
-CONFIG_OMAP_USB2=m
+CONFIG_USB_NET_DRIVERS=y
+CONFIG_USB_USBNET=y
+CONFIG_USB_NET_SMSC95XX=y
+CONFIG_USB=y
+CONFIG_USB_EHCI_HCD=y
+CONFIG_USB_EHCI_HCD_OMAP=y
+CONFIG_NOP_USB_XCEIV=y
+# CONFIG_USB_GADGET is not set
+CONFIG_OMAP_USB2=y

I had to disable CONFIG_USB_GADGET is compiling it as a module prevents 
selecting CONFIG_NOP_USB_XCEIV=y, which is a dependency for 
CONFIG_USB_EHCI_HCD_OMAP=m.

The new configuration resulted in a few changes, among which the most notable 
is

-# CONFIG_USB_MUSB_HOST is not set
-# CONFIG_USB_MUSB_GADGET is not set
-CONFIG_USB_MUSB_DUAL_ROLE=y
+CONFIG_USB_MUSB_HOST=y

I then get the same error as originally reported.

Yeah OK, that's the problem.. We still have musb hardware
trying to do things on it's own and phy trying to detect
the state.

Any ideas why we have a dependency like that in Kconfig?

Well, with CONFIG_USB_GADGET disabled, I don't expect CONFIG_USB_MUSB_GADGET 
to be enabled. MUSB can only operate in host mode in that case, so musb-

I've tried to investigate this but I'm not familiar enough with the MUSB 
driver to reach any conclusion. Felipe, if you have time could you give me a 
hand ?

To summarize the issue, on a pandaboard-es where the MUSB is wired to an OTG 
connector with mode rightfully set to MUSB_PORT_MODE_DUAL_ROLE in DT, a kernel 
configured with CONFIG_USB_MUSB_HOST=y (for instance because CONFIG_USB_GADGET 
is disabled) will print an endless stream of the following meessage.

[    2.766174] musb_bus_suspend 2586: trying to suspend as a_idle while active

musb_init_controller() performs the following actions

        case MUSB_PORT_MODE_DUAL_ROLE:
                status = musb_host_setup(musb, plat->power);
                if (status < 0)
                        goto fail3;
                status = musb_gadget_setup(musb);
                if (status) {
                        musb_host_cleanup(musb);
                        goto fail3;
                }
                status = musb_platform_set_mode(musb, MUSB_OTG);
                break;

and as gadget support is disabled musb_gadget_setup() compiles to a no-op 
inline function. The system is thus configured in host mode by 
musb_host_setup() with musb->xceiv->otg->state = OTG_STATE_A_IDLE. A later 
call to musb_start() verifies the condition

        if (musb->port_mode != MUSB_PORT_MODE_HOST &&
                        musb->xceiv->otg->state != OTG_STATE_A_WAIT_BCON &&
                        (devctl & MUSB_DEVCTL_VBUS) == MUSB_DEVCTL_VBUS) {

and sets musb->is_active to 1. Later, musb_bus_suspend() complains because 
is_active is not 0.

What is wrong in that sequence ?

I don't have a omap3/4 platform to test on this, but I don't see this
problem on am335x board.

To get there, devctl[MUSB_DEVCTL_VBUS] bits have to be set, where does the
vbus voltage come from? Session is not on yet.

I think the issue is pandaboard connected to a PC with mini-B
cable while musb is being forced to host mode?

Which board is that ? For the problem to occur the board has to have an OTG 
connector.

MUSB_DEVCTL is first set to 0 by musb_generic_disable() called from 
musb_init_controller(). The register is then left untouched (as far as I can 
tell, I've intercepted all musb_writeb() and musb_readb() calls) until 
musb_start() to reads the register. The read value has BDEVICE and VBUS=3 set.

The issue also occurs when the cable isn't connected.

It is the TI am335x GP EVM, which usb0 port has an otg receptacle, and a
power switch controlled by usb0 drvvbus pin.

The DEVCTL_VBUS bits are set by the controller, when it sense VBUS
voltage > VBUS_VALID.

If the otg port is not connected to a host but you still get VBUS=3, the
vbus voltage must be provided from the board itself. We have to check
the schematics to see how it is possible. This is pandaboard es, right?
Assume I will be able to find its schematics on internet...

It would seem that the voltage is provided by the TWL6030. I'm not sure what's 
turning it on as the MUSB driver doesn't seem to perform any set_vbus call in 
the faulty configuration (I've traced musb_platform_set_vbus(), 
omap2430_musb_set_vbus(), otg_set_vbus(), omap_usb_set_vbus() and 
twl6030_set_vbus() and none of them get called).

An interesting point to note is that the TWL6030 gets probed after MUSB when 
MUSB is configured in host mode only, and that happens after the call to 
musb_start().

just gave 4.9.0 more testing on IGEPv2 board (DM3730 based), schematics here:
https://www.isee.biz/support/downloads/item/igepv2-rc-schematics

musb is configured in host only mode, driver compiled in. ID pin is grounded,
VBUS not connected, D+, D-, and GND are connected to self powered hub.

$ lsusb -t

1) without following patch I'm getting:

   however, devices get enumerated

Anyone has a clue how to fix 2?

I think that's because musb needs to stay awake a little while to
negotiate with the PHY over ULPI whatever. Otherwise I think the PHY
might not idle properly, or might be in some unknown state?

If you have ID pin grounded, then a_idle is where we'd expect things
to be. That still does not explain why it's stuck in a loop though.

OK yeah host mode VBUS errors are common if the VBUS voltage does not
come up fast enough for musb.

No idea.. Maybe try to add some printks to see why active is set
at that point?

Actually disabling CONFIG_USB_MUSB_HDRC gets rid of the problem, quite 
understandably. It's not a fix though, just a workaround. Are you interested 
in investigating this ?

I'm seeing this too. Did you manage to boot your Panda? If I disable
CONFIG_USB_MUSB_HDRC, I don't see that error print, but the ethernet
doesn't work, and so my nfsroot doesn't mount.

Do you use ethernet over USB gadget or over LAN9514 (smsx95xx) ? The LAN9514 
is connected to the EHCI USB interface so it shouldn't depend on MUSB.

I've attached my .config to this e-mail.

smsx95xx. I didn't look at it further, so possibly there's something
else broken/changed that prevented the ethernet from working.

I have omap2plus_defconfig with initramfs work just fine for nfsroot
and musb peripheral mode on pandaboard es. Well I have not tried it
since last week with Linux next.

Ok, I found the issue. I had to enable CONFIG_NOP_USB_XCEIV. (the
musb_bus_suspend issue is still there, though).

OK. And what changes to your current .config make the musb_bus_suspend()
issues show up?

If it happens with USB-B cable from host to musb with musb set to host

I have no USB cables connected. I have attached my config. If
CONFIG_USB_MUSB_HDRC is disabled, the musb error goes away.

Maybe compare against omap2plus_defconfig? If you have musb
set to host only mode it still tries to follow the ID pin
from phy and do things on it's own. And ID pin is floating
in B mode and with no cable connected.

AFAIK, the only sane configuration for musb is the OTG mode
because the hardware tries to do things on it's own. And the
host only mode only really works if phy has ID pin grounded
or else the phy has to do trickery to rewrite the state to
musb.

Tony

For what it's worth, that's exactly the same problem I experienced. See 
https://www.spinics.net/lists/linux-usb/msg149172.html for an analysis.

The problem is that with the built-in musb configuration we're trying to
set USB-B cable to host mode with ID pin not grounded. That's not going
to work on most hardware unless the PHY can configure the ID pin.

Here's how to fix the .config for built-in musb:

1. Change to have CONFIG_USB_GADGET=y

2. Then change CONFIG_USB_MUSB_DUAL_ROLE=y instead of CONFIG_USB_MUSB_HOST

We should probably get rid of CONFIG_USB_MUSB_HOST to avoid this.

Tony

The reason I went for host mode is that I had to disable CONFIG_USB_GADGET as 
compiling it as a module prevents selecting CONFIG_NOP_USB_XCEIV=y, which is a 
dependency for CONFIG_USB_EHCI_HCD_OMAP=m.

config NOP_USB_XCEIV
        tristate "NOP USB Transceiver Driver"
        depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, NOP can't be 
built-in
        select USB_PHY

OK well like I said the CONFIG_USB_MUSB_HOST selection for a USB-B cable
won't work from the hardware point of view. The only case where it works
is if the PHY ID pin is grounded. Anything else will be flakey and won't
prevent musb from attempting to change it's state on it's own.

No idea why it's done that way..
