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:
