+Qualcomm adreno/snapdragon hdmi output
+
+Required properties:
+- compatible: one of the following
+   * "qcom,hdmi-tx-8996"
+   * "qcom,hdmi-tx-8994"
+   * "qcom,hdmi-tx-8084"
+   * "qcom,hdmi-tx-8974"
+   * "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
+- power-domains: reference to the power domain(s), if available.
+- pinctrl-names: the pin control state names; should contain "default"
+- pinctrl-0: the default pinctrl state (active)
+- pinctrl-1: the "sleep" pinctrl state
