Hi all,
this is a follow up on the patch "USB: EHCI: Initialize multiple
USB controllers at once" from Jim Lin. It takes some of the
code but has undergone some heavy reworking.
When we remove the ifdef horror from the above mentioned patch it's
mostly a big interface change to the usb subsystem. As this creates
a lot of churn I've split this up into a series. Every patch is self
contained so it doesn't break compiles and *should* not regress
any functionality on it's own. At least the series is bisectable in
case anything goes wrong. I've compile tested all the ARM configs.
Both the lowlevel usb and ehci interface change are backward
compatible, so implementations that only use one controller can
choose to ignore the new interface. All implementations are
updated to work with the new function prototypes.
For Tegra I've included a patch to actually use the new ehci
interface. Patches are based on a Tegra tree with some relevant
changes from u-boot-usb picked over, so they should apply to
u-boot-usb/master.
Patch 4 also includes some cosmetic changes, to make the output
of the usb commands more readable.
On my Colibri T20, with a total of 3 usb controllers of which 2
are enabled in the device tree, output now looks like this:
Tegra20 (Colibri) # usb start
(Re)start USB...
USB0: USB EHCI 1.00
scanning bus 0 for devices... 2 USB Device(s) found
USB1: USB EHCI 1.00
scanning bus 1 for devices... 2 USB Device(s) found
USB2: lowlevel init failed
scanning usb for storage devices... 1 Storage Device(s) found
scanning usb for ethernet devices... 1 Ethernet Device(s) found

To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean.

There is no logic change in OMAP up to now. I just had to add some forward decls to make it work, which would not be needed if OMAP worked like all the other platforms. Actually fixing this would be far more invasive and I don't really want to do this work, as I don't have a single OMAP board to test with. > Also, I'd fix all these &(*something)->somethingelse if possible. > I just did it this way to minimize the churn this change is causing. Removing this, arguably a bit ugly, pointer construct could possibly introduce logic errors, that are not catchable by just compile testing this.

Can you explain what this series is based on in a little more detail? I tried applying it to Tegra's for-next today, and it wouldn't apply.

I'm fighting through pile of hacking now, so didn't get to rebasing (!) u-boot-usb on top of master yet. But it should be safe to rebase this on top of master. Are we clear on the rest of comments?

I'd say reorder 3/4 and 4/4 (swap them) and then repost the rebased result. I'll pick it all.

Just because I like doing one thing at a time. Getting all the USB related changes integrated so far seemed to be enough work for me to keep up with. Moving the Tegra USB implementation is still somewhere on my list of things to do. Maybe it would be better to also take the whole Tegra ULPI patchset through the USB tree. This would minimize the dependencies of both trees and would allow to easily move the implementation in a follow-on patchset. But for this to work out we would have to agree to base all further Tegra USB patches for this cycle (if there are any) on the u-boot-usb tree.

To: u-boot
V5: rebased on a non-stale version of u-boot-usb/master
V4: Fixed build failures in fsl and mxs ehci code. Also rebased on
the latest usb/master and did MAKEALL -a powerpc in addition to
MAKEALL -a arm.
V3: Stephen ran into some problems applying this, as it seems my tree
wasn't as clean as it should have been. Sorry for the inconvenience.
This should now be fixed.
Hi all,
this is a follow up on the patch "USB: EHCI: Initialize multiple
USB controllers at once" from Jim Lin. It takes some of the
code but has undergone some heavy reworking.
When we remove the ifdef horror from the above mentioned patch it's
mostly a big interface change to the usb subsystem. As this creates
a lot of churn I've split this up into a series. Every patch is self
contained so it doesn't break compiles and *should* not regress
any functionality on it's own. At least the series is bisectable in
case anything goes wrong. I've compile tested all the ARM configs.
Both the lowlevel usb and ehci interface change are backward
compatible, so implementations that only use one controller can
choose to ignore the new interface. All implementations are
updated to work with the new function prototypes.
For Tegra I've included a patch to actually use the new ehci
interface. Tom, Stephen, can I get an ACK from you for this, so
Marek can take this through his USB tree?
All patches now rebased onto u-boot-usb/master.
Patch 3 also includes some cosmetic changes, to make the output
of the usb commands more readable.
On my Colibri T20, with a total of 3 usb controllers of which 2
are enabled in the device tree, output now looks like this:
Tegra20 (Colibri) # usb start

To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean.
