[PATCH 0/1] Possibly fix USB OTG on GTA04 and N900

[Roger Quadros]

Hi,

USB OTG on these boards might be broken on Greg's usb-next branch [1]
after the Generic PHY framework and associated patches were merged.

This is a probable fix but I'm not able to test these boards. Please
give it a try and your Ack if it works. Thanks.

Would it be much pain (and do we want this at all) to add a fallback
into the kernel or at least a printk pointing out to update the .dts
for two releases or so? So the user does not need to spent hours to
figure out why it suddenly stopped working.

I agree with you. 

Also, figuring out which kernel configs to enable for
USB OTG to work on OMAP is a pain in itself to the user.

I have tested the Nokia N900 part of the patch. Without this patch
the USB port does not work:

[    1.015014] musb-omap2430 480ab000.usb_otg_hs: unable to find phy

With the patch everything seems to work.
