From: Hans Verkuil <hans.verkuil@xxxxxxxxx> 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). Note: the Dragonboard needs this patch: https://patchwork.kernel.org/patch/9824773/ Archit, can you confirm that this patch will go to kernel 4.14?
Yes, it's been queued to clk-next. Thanks, Archit
And the Koelsch board needs this 4.13 fix: https://patchwork.kernel.org/patch/9836865/ 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 Hans Verkuil (4): dt-bindings: adi,adv7511.txt: document cec clock arm: dts: qcom: add cec clock for apq8016 board arm: dts: renesas: add cec clock for Koelsch board drm: adv7511/33: add HDMI CEC support .../bindings/display/bridge/adi,adv7511.txt | 4 + arch/arm/boot/dts/r8a7791-koelsch.dts | 8 + arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi | 2 + drivers/gpu/drm/bridge/adv7511/Kconfig | 8 + drivers/gpu/drm/bridge/adv7511/Makefile | 1 + drivers/gpu/drm/bridge/adv7511/adv7511.h | 45 ++- drivers/gpu/drm/bridge/adv7511/adv7511_cec.c | 314 +++++++++++++++++++++ drivers/gpu/drm/bridge/adv7511/adv7511_drv.c | 152 +++++++++- drivers/gpu/drm/bridge/adv7511/adv7533.c | 30 +- 9 files changed, 514 insertions(+), 50 deletions(-) create mode 100644 drivers/gpu/drm/bridge/adv7511/adv7511_cec.c
