At least the EHCI/OHCI found on the Allwinnner H3 SoC needs multiple
reset lines, the controller will not initialize while the reset for
its companion is still asserted, which means we need to de-assert
2 resets for the controller to work.

This patch doesn't apply to my usb-testing branch at all, what went
wrong?

You merged this patch:

https://git.kernel.org/cgit/linux/kernel/git/gregkh/usb.git/commit/?id=d0e08b0077f49e209bc90305ddf1ca434ac6cc0e

Which does almost the same, except that it only supports dedicated reset
controllers and not shared reset controllers.

I'll send a new patch which changes things to add support for shared
reset controllers.

This will also bring the ehci-platform reset handling code inline
with ohci-platform again.

Regards,

Hans
