The A10-EVB from Allwinner comes with an unidentified panel, with the only mark on the PCB being A10-SUB-EVB-5LCD.

Add timings to simple panel to handle it.

I assume the numbers came from the fex file? Allwinner LCD timing numbers aren't very precise. This seems to yield a refresh rate of 58.x Hz. The dot clock can go below MHz resolution, so it should be possible to set it to a more proper clock rate here.

The GR8 is an SoC made by Nextthing loosely based on the sun5i family.

Since it's not clear yet what we can factor out and merge with the A10s and A13 support, let's keep it out of the sun5i.dtsi include tree. We will figure out what can be shared when things settle down.

IIRC, Hans made OTG work with boards that don't have VBUS control. All you need is a powered hub. And since there's no chance of VBUS going back through the connection to hurt the host on the other end when in peripheral mode, I think it's ok to put it in OTG mode here.

The rest looks fine.
