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.
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 managed to apply using plain "patch" rather then "git am", but then I get a bunch of compile errors:-(
