[PATCH v5 00/14] usb: phy: msm: Fixes, cleanups and DT support

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

Hi,

This is a fifth version of patches posted earlier here [1].

They have been tested on AP8074 DragonBoard. Only gadget
mode utilized for now.

CV Test Suite engine "Chapter 9 tests" are passing except
"Halt Endpoint Test".

usbtest driver report following failure:
test 13 --> 32 (Broken pipe)    ep 81 couldn't set halt, -32

Changes since v4:
 - Drop patch [1/15] usb: phy: msm: Move mach dependent code to platform data
   it is already merged.
 - Address comments regarding devicetree bindings.

[1] https://lkml.org/lkml/2013/11/12/298

[PATCH v5 03/14] usb: phy: msm: Remove unnecessarily check for valid regulators.

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

Whether regulators are available or not is checked at driver
probe. If they are not available driver will refuse to load,
so no need to check them again.

[PATCH v5 05/14] usb: phy: msm: Replace custom enum usb_mode_type with enum usb_dr_mode

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

Use enum usb_dr_mode and drop default usb_dr_mode from platform data.

USB DT bindings states: dr_mode: "...In case this attribute isn't
passed via DT, USB DRD controllers should default to OTG...",
so remove redundand field.

[PATCH v5 06/14] usb: phy: msm: Remove unused pclk_src_name

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

There are no references to 'pclk_src_name' in plaform code,
so it is unused.

[PATCH v5 07/14] usb: phy: msm: Remove HSUSB prefix from regulator names

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

Prefix did not bring any useful information. Currently none
of the MSM platforms define these regulators, so it is safe
to rename them.

[PATCH v5 11/14] usb: phy: msm: Add support for secondary PHY control

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

Allow support to use 2nd HSPHY with USB2 Core.
Some platforms may have configuration to allow USB controller
work with any of the two HSPHYs present. By default driver
configures USB core to use primary HSPHY. Add support to allow
user select 2nd HSPHY using DT parameter.

[PATCH v5 12/14] usb: phy: msm: Correct USB PHY Reset sequence for newer platform

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

On few legacy platforms, USB PHY is having dedicated reset clk.
It is used to reset USB PHY after putting USB PHY into low power
mode and for calibration of USB PHY. Putting USB PHY into low
power mode is causing ulpi read/write timeout as expected. USB PHY
reset clk is not available on newer platform.

For 28nm PHY, reset USB PHY after resestting USB LINK.
Also reset USB PHY using USB_PHY_PON bit with USB_OTG_HS_PHY_CTRL
register after programming USB PHY Override registers as suggested
with hardware programming guidelines.

[PATCH v5 14/14] usb: phy: msm: Vote for corner of VDD CX instead of voltage of VDD CX

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

New platform uses RBCPR hardware feature, with that voting for
absolute voltage of VDD CX is not required. Hence vote for corner of
VDD CX which uses nominal corner voltage on VDD CX.

Re: [PATCH v5 00/14] usb: phy: msm: Fixes, cleanups and DT support

[Tim Bird]

Ivan,

I'm still unsuccessful at getting this patch set to work on my kernel.
 Below is a sequence of register dumps showing the boot (and reset
during boot).  It shows a status transition in my kernel when I pull
the controller out of reset, and re-write PORTSC:PTS to ULPI
(simultaneously writing other bits in PORTSC to 0) This is at 3.109535
in the boot log below.  The status I'm seeing back from the other
registers doesn't make sense, and is different from what I see in 3.4
(where USB runs successfully on the board).  Is there some connection
between the PMIC and the USB that I'm missing?  The transition from
vbus B session valid to vbus B session end seems wrong (as does the
ULPII transitioning to 1).

In measuring voltages on the board, it appears that that vbus from the
connector (at 5V) gets routed through the PMIC, but comes out at 3.3V
on its way to the PHY VBUS input (measured at R179).  This seems
really weird - maybe you can shed some light on what is going on here.

Could you possibly send me your zImage and dtb file, so I can test
them on my board to make sure that the hardware is working?

Thanks,
 -- Tim

Not looking good, too late for v3.15.

It will be nice if you could pick up first several patches, which are
just cleanups.

the only answer was "Thanks I'll fix it". To which there was never a

unfortunately I have already sent my pull request to Greg :-(

I could try to get some of those in during the -rc cycle, but it's
unlikely Greg will let me :-)

Thanks very much for trying things out, sharing your command line,
patches and setup, etc.

Here is a random stream of thoughts....

On my board, the 3.4 kernel works, and fastboot works, so clearly the
hardware is capable of
operating correctly.  I've tried booting the 3.14 kernel from cold
boot (so avoiding USB setup
by fastboot), as well as from warm reset.  In all cases, the register
dumps from the controller
and the phy show that the state of the controller and phy are the same
between 3.4 and 3.14
when the kernel starts (well, after the register area is mapped, but
before the USB driver initializes).

However, the state of the registers quickly diverges.  In the 3.14
case (at least on my 3.14 kernel,
where I have instrumentation *1), I see exactly the same transition
every time.  The phy hardware gets
stuck in a mode where it is NOT seeing vbus valid (while the 3.4
kernel does), and worse, the ULPI_FUNC_CTRL
register shows an OpMode of "disable bit-stuff and NRZI encoding"
(which is 10b), where the 3.4 kernel
shows an OpMode of "normal" (00b).

I don't think any communication can happen on the USB bus with the PHY
OpMode in this state.

Also, on 3.4 the PSPD (port speed) field of the PORTSC register
transitions to "High Speed",
while in 3.14 the PSPD field stays forever in an unknown (11b) state.
Again, I don't think there
can be any valid communication on the USB bus when the PHY doesn't
even have it's basic
speed state correct.

I tried a couple of experiments with the 3.4 kernel.  USB on 3.4
doesn't work if I switch the otg-control to
"phy control" rather than "pmic" control.  So I've started looking at
the differences in the code
paths on 3.4 that are affected by this setting (unfortunately, it's a
lot of code).

With regard to board version, here is my information:

On the daughter-board, there is a white paper sticker which says:
Snapdragon 800 Series
APQ8074 SOM
SN: 199-0200-090813-00331
MAC: 0x00D0CAF1BD81

In white letters on the SOM itself, it has written:
APQ8074 SOM
DRAGONBOARD
199-0200

*1 - One of my next steps is to instrument the 3.14 code I got from
you, to see if I'm getting the
same register status as I do with my 3.14 code.

All along I have been thinking that my code was not doing something it
needed to, in order to
reset the PHY (like starting a regulator, setting up a clock, or
putting something correct into a
register).  But I have, by now, a pretty much identical sequence of
regulator, clock, reset,
interrupt, controller, and phy operations between 3.4 and 3.14.  The
next thing to look at is if
there is any extra relationship between the PMIC and the controller
and PHY, that 3.4 handles correctly (or that your
code handles correctly on your board), that I'm missing on my board.

It's quite frustrating, but thanks very much for your help.

Re: [PATCH v5 00/14] usb: phy: msm: Fixes, cleanups and DT support

[Tim Bird]

Here's some more progress.

I can successfully get the dragonboard to establish a USB connection
to the host (have the host enumerate it) with this code, but only if I
first boot the machine to fastboot, then boot the kernel from ramboot.
 When I boot the kernel from RAM, the device comes right up, after the
g_zero module is loaded.

Ivan,

Can you tell me if you are booting from RAM or from flash?  If you are
booting from RAM (doing something like 'fastboot boot boot.img' to
start the kernel), then could you try instead writing the kernel to
flash and booting directly to it, without first going into fastboot,
and let me know what happens.  In my situation, clearly there's some
element of hardware setup that fastboot does that my kernel can rely
upon for working, that my kernel alone does not perform.

Thanks for any info you can provide.

I will look what aboot is doing and add same sequence to driver.

It was small, but important difference. There is MUX, which selects 
which port to be used by USB2.0 controller. On DragonBord8074 it
should be second one. This is what "qcom,phy-num" DT property supposed
to select. Unfortunately this is not enough. Register 0xfd4ab000 should
contain value different than zero. Example of this can be seen in
qcom,dwc3 driver [1].
