version 2:
- fix typo in compagnie name
- add yannick sign-off
- use cec_message instead of custom struct in cec device
- add monitor mode
I don't change the split between irq handler and irq thread because
it would had mean to handle all errors cases irq handler to keep
a correct sequence. I don't think it is critical as it is since cec is a very
slow protocol.
This serie of patches add cec driver for STM32 platforms.
This code doesn't implement cec notifier because STM32 doesn't
provide HDMI yet but it will be added later.
Those patches have been developped on top of media_tree master branch
where STM32 DCMI code has not been merged so conflict in Kconfig and Makefile
could occur depending of merge ordering.
Compliance has been tested on STM32F769.
