Qualcomm adreno/snapdragon hdmi output
Required properties:
- compatible: one of the following
* "qcom,hdmi-tx-8660"
* "qcom,hdmi-tx-8960"
- reg: Physical base address and length of the controller's registers
- reg-names: "core_physical"
- interrupts: The interrupt signal from the hdmi block.
- clocks: device clocks
See ../clocks/clock-bindings.txt for details.
- qcom,hdmi-tx-ddc-clk-gpio: ddc clk pin
- qcom,hdmi-tx-ddc-data-gpio: ddc data pin
- qcom,hdmi-tx-hpd-gpio: hpd pin
- core-vdda-supply: phandle to supply regulator
- hdmi-mux-supply: phandle to mux regulator
Optional properties:
- qcom,hdmi-tx-mux-en-gpio: hdmi mux enable pin
- qcom,hdmi-tx-mux-sel-gpio: hdmi mux select pin
