There is now support for the multiport USB controller this uses so

The board only has a single port hooked up (despite it being wired up to
the multiport IP on the SoC). There's also a USB 2.0 mux hooked up,
which by default on boot is selected to mux properly. Grab the gpio
controlling that and ensure it stays in the right position so USB 2.0
continues to be routed from the external port to the SoC.

Hi Konrad,

  Sure, will add a default value for drive-strength for this pinctrl node.

Hi Andrew Halaney,

I currently don't have a Ride device with me to test this change. Can you help test this patch on SA8540-Ride including (drive-strength = <2>;) property (which I believe is the default value).

I can test the same on SA8295-ADP and can push the next version quickly.

Regards,
Krishna,
