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.
queued to drm-misc-next.
Thanks, Archit
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
