* Silicon Image-8620 MHL Tx

Required properties:
- compatible: must be "sil,sii-8620"
- reg: i2c slave address
- sil,pwr-gpio: MHL power gpio required to power sii8620
- sil,fw-wake: MHL fw wake gpio going into sii8620
- sil,reset-gpio: MHL reset gpio going into sii8620 for toggling reset pin
- sil,irq-gpio: MHL interrupt gpio coming out of sii8620
- sil,i2c_port#: Port number of i2c device
- pinctrl-0: Pin control group to be used for this controller.
- pinctrl-names: Should contain only one value - "mhl_active".

Example:
	i2c@f9923000 {
		sil,sii-8620@72 {
			compatible = "sil,sii-8620";
			reg = <0x72>;
			sil,pwr-gpio = <&pm8994_gpios 2 0>;
			sil,fw-wake = <&msm_gpio 38 0>;
			sil,reset-gpio = <&msm_gpio 58 0>;
			sil,irq-gpio = <&msm_gpio 57 0>;
			sil,i2c_port# = <1>;
			pinctrl-names = "mhl_active";
			pinctrl-0 = <&mhl_intr_active &mhl_reset_active>;
		};
