The ROCK 4D uses an ADC input to distinguish between a headphone (i.e.,
no mic) and a headset (i.e., with mic). After some searching, it appears
that the closest we can get to modelling this is by sending a particular
switch input event.

So this series modifies the adc-keys bindings, extends the adc-keys
driver to allow sending other input types as well, and then adds the
analog and HDMI audio nodes to ROCK 4D's device tree.

Applied, thanks!
