1Qualcomm adreno/snapdragon hdmi output
2
3Required properties:
4- compatible: one of the following
5 * "qcom,hdmi-tx-8084"
6 * "qcom,hdmi-tx-8074"
7 * "qcom,hdmi-tx-8660"
8 * "qcom,hdmi-tx-8960"
9- reg: Physical base address and length of the controller's registers
10- reg-names: "core_physical"
11- interrupts: The interrupt signal from the hdmi block.
12- clocks: device clocks
13 See ../clocks/clock-bindings.txt for details.
14- qcom,hdmi-tx-ddc-clk-gpio: ddc clk pin
15- qcom,hdmi-tx-ddc-data-gpio: ddc data pin
16- qcom,hdmi-tx-hpd-gpio: hpd pin
17- core-vdda-supply: phandle to supply regulator
