Cover letter [U-Boot] [PATCH v4 0/4] USB multi controller
Dear Lucas Stach,
Patchset doesn't apply ... rebase and repost please.
Quoted 111 lines
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:
