* Silicon Image-8334 MHL Tx

Required properties:
- compatible: must be "qcom,mhl-sii8334"
- reg: i2c slave address
- mhl-intr-gpio: MHL interrupt gpio coming out of sii8334
- mhl-pwr-gpio: MHL power gpio required for power rails
- mhl-rst-gpio: MHL reset gpio going into sii8334 for toggling reset pin
- <supply-name>-supply: phandle to the regulator device tree node.
- qcom,hdmi-tx-map: phandle to the hdmi tx device tree node.

Example:
	i2c@f9967000 {
		sii8334@72 {
			compatible = "qcom,mhl-sii8334";
			reg = <0x72>;
			interrupt-parent = <&msmgpio>;
			interrupts = <82 0x8>;
			mhl-intr-gpio = <&msmgpio 82 0>;
			mhl-pwr-gpio = <&msmgpio 12 0>;
			mhl-rst-gpio = <&pm8941_mpps 8 0>;
			avcc_18-supply = <&pm8941_l24>;
			avcc_12-supply = <&pm8941_l2>;
			smps3a-supply = <&pm8941_s3>;
			vdda-supply = <&pm8941_l12>;
			qcom,hdmi-tx-map = <&mdss_hdmi_tx>;
		};
