But what if the chip is connected to a display controller, for instance to the HDMI output of an SoC ? Is that a use case for the hardware ?

The ANX7814 is an ultra-low power Full-HD (1080p60) SlimPort transmitter designed for portable devices. You can add support to your board with current binding. Example: anx7814: anx7814@38 { compatible = "analogix,anx7814"; reg = <0x38>; pd-gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>; reset-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>; }; Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> --- .../devicetree/bindings/video/bridge/anx7814.txt | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 Documentation/devicetree/bindings/video/bridge/anx7814.txt
