[Arm-netbook] Allwinners A10 Board: Feature suggestion - HDMI CEC

[Ken Phillis Jr]

I figure since HDMI is already listed as one of the features supported
by the device, it would work better to go ahead and work on improving
the device by making sure that HDMI Consumer Electronics Control  (
CEC ) is added. This should work out fine since it's only connecting
one pin on the HDMI port. As for the use of HDMI CEC it's a in-wire
control system used to control devices like dvd/bluray players,
televisions, cable set top boxes, sorround sound systems, and numerous
other devices. There is already open source work on this using the
Arduinoboard ( atmega series chip ) and the TI msp430 chip.

As for the hardware changes, this involves Pin 13 and 17 of the hdmi cable.

As for the library status, Currently a GPL v3 library exists for the
TI MSP430 chip, and it can probably be modified to work on the
allwinner chip.
