Thanks for the patch,
but I see some things that could be improved.

IIRC if you force that dual role port to work as a host it will work fine.

A PWM-controller vbibration motor too.

I wasn't able to find the part number of the panel, nor the manufacturer.
It might be a custom made part.
On the flex PCB there are markings:
"YLM-355604-B-A1", underneath it in smaller font is "2201",
and on the other side, much less visible, "WL-355604-A1".
I tried disassembling the panle itself, and there were
still no markings. :/
The touchscreen is a Hynitron CST340.
This device also has a SGM4865 audio amplifier,

Maybe we could still include dose in dts file, as it's supposed to
describe the hardware?

Maybe it could be named in a way that would
be more in-line with what the button actually is, instead
of a random number?
