From: Hans Verkuil <hans.verkuil@xxxxxxxxx> I should have posted this a month ago, but I completely forgot about it. Apologies for that. 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 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 Hans Verkuil (2): dt-bindings: adi,adv7511.txt: document cec clock drm: adv7511/33: add HDMI CEC support .../bindings/display/bridge/adi,adv7511.txt | 4 + drivers/gpu/drm/bridge/adv7511/Kconfig | 8 + drivers/gpu/drm/bridge/adv7511/Makefile | 1 + drivers/gpu/drm/bridge/adv7511/adv7511.h | 43 ++- drivers/gpu/drm/bridge/adv7511/adv7511_cec.c | 337 +++++++++++++++++++++ drivers/gpu/drm/bridge/adv7511/adv7511_drv.c | 116 ++++++- drivers/gpu/drm/bridge/adv7511/adv7533.c | 38 +-- 7 files changed, 489 insertions(+), 58 deletions(-) create mode 100644 drivers/gpu/drm/bridge/adv7511/adv7511_cec.c -- 2.14.1 -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
