This patch implements a driver supporting Synaptics ClearPad and other
touchscreen sensors that use the RMI4 protocol, as defined here:

OK I looked over the parts I understood, to my surprise there is a
custom GPIO, LED and ADC driver in there, and none of them use
the proper kernel subsystems.

You may want to expose the bus in <linux/input/rmi4.h> or so, and
put the drivers for these into e.g.

drivers/gpio/gpio-rmi4.c
drivers/leds/leds-rmi4.c
drivers/iio/adc/rmi4.c

Which would be nice. (Kconfig can make sure they're only available
when enabling the bus.)

As for the input stuff I mainly looked at the stuff I understand...
