Not everything works yet, but a lot does work:

* serial
* display
* keyboard
* touchscreen
* slider/power button

What doesn't work yet:

* display backlight
* keyboard backlight

The stock kernel ramoops range might be different here because of less
memory. If the stock kernel has it, it should be in the platform data
somewhere in the stock kernel sources. Probably best to just leave it
out for now.

Just leave this out too, I don't think we have the ramoops configured in
the mainline kernel.

Otherwise looks good to me.

Understood -- I didn't see it in the stock kernel, so perhaps ramoops is
not available on this device.

Oops, yeah.

This is same as Droid 4, good.

This one is new. We should make sure it is same label as on PCs, and
then document it in Documentation/leds/well-known-leds.txt .

Best regards,
