[U-Boot] [PATCH] ARM: rpi: enable USB keyboard

[U-Boot] [PATCH] ARM: rpi: enable USB keyboard

[Stephen Warren]

Now that the DWC2 driver supports split transactions, we can reasonably
enable support for USB keyboards. This wasn't terribly useful before
since keyboards are usually LS/FS devices, and thus require split
transaction support when attached to a USB hub such as the hub built into
the RPi model Bs.

This depends on Stefan Br?ns' series "usb: dwc2: add SPLIT transaction
support".

In that case, I am putting both into u-boot-usb/dwc2 for now, until the dwc2
patchset gets more fleshed out . Thanks!

Best regards,
