Hi Mauro,
This patch series adds a bunch of little improvements but most importantly
it adds the low-level CEC pin support for hardware that just polls/drives the
CEC pin and needs software to handle the low-level CEC bus protocol.
This will be used by the AllWinner A10 drm driver:
https://patchwork.linuxtv.org/patch/42411/
That driver will be merged for 4.14 via the drm subsystem.
It will also be used by the upcoming cec-gpio driver:
https://patchwork.linuxtv.org/patch/42213/
But that isn't ready yet. It may or may not be finished in time for 4.14, we'll
see.
This low-level CEC pin support code will also be used in the future to
implement error injection of the CEC bus, but the API for that needs to be
reworked quite a bit.
Regards,
Hans
