This patch series adds CEC support to the drm adv7511/adv7533 drivers.

I have tested this with the Qualcomm Dragonboard C410 (adv7533 based)
and the Renesas R-Car Koelsch board (adv7511 based).

I only have the Koelsch board to test with, but it looks like other
R-Car boards use the same adv7511. It would be nice if someone can
add CEC support to the other R-Car boards as well. The main thing
to check is if they all use the same 12 MHz fixed CEC clock source.

Anyone who wants to test this will need the CEC utilities that
are part of the v4l-utils git repository:

git clone git://linuxtv.org/v4l-utils.git
cd v4l-utils
./bootstrap.sh
./configure
make
sudo make install

Now configure the CEC adapter as a Playback device:

cec-ctl --playback

Discover other CEC devices:

cec-ctl -S

Regards,

	Hans

Changes since v2:
- A small rewording of the 'clocks' property description in the bindings
  as per Sergei's comment.

Changes since v1:
- Incorporate Archit's comments:
	use defines for irq masks
	combine the adv7511/33 regmap_configs
	adv7511_cec_init now handles dt parsing & CEC registration
- Use the new (4.14) CEC_CAP_DEFAULTS define
