msm: adv7533: add DSI to HDMI bridge chip support

ADV7533 DSI to HDMI bridge

Required properties:

- compatible:				Must be "adv7533"

- reg:					Main I2C slave ID (for I2C host driver)

- adi,video-mode:			Excepted a number and possible inputs are 0 to 3, while:

					3 = 1080p

					2 = 720p

					1 = 480p

					0 = 1080p pattern

- adi,main-addr:			Main I2C slave ID

- adi,cec-dsi-addr:			CEC DSI I2C slave ID

Optional properties:

- adi,enable-audio:

- adi,disable-gpios:

- adi,irq-gpio:			Main IRQ gpio mapping

- adi,hpd-irq-gpio:			HPD IRQ gpio mapping

- adi,switch-gpio:			DSI switch gpio mapping

Example:

&soc {

	i2c@78b8000 {

		adv7533@39 {

			compatible = "adv7533";

			reg = <0x39>;

			adi,video-mode = <3>; /* 3 = 1080p */

			adi,main-addr = <0x39>;

			adi,cec-dsi-addr = <0x3C>;

			adi,enable-audio;

			pinctrl-names = "pmx_adv7533_active","pmx_adv7533_suspend";

			pinctrl-0 = <&adv7533_int_active &adv7533_hpd_int_active &adv7533_switch_active>;

			pinctrl-1 = <&adv7533_int_suspend &adv7533_hpd_int_suspend &adv7533_switch_suspend>;

			adi,irq-gpio = <&msm_gpio 31 0x2002>;

			adi,hpd-irq-gpio = <&msm_gpio 20 0x2003>;

			adi,switch-gpio = <&msm_gpio 32 0x0>;

		};

	};

	---help---

	  Support for MSM display bridge abstraction interface. MSM display

	  drivers can use the same interface to interact with different third

	  bridge chip. The MSM DBA driver maintains a list of devices supported

	  on the platform and allow clients to register and access these

	  devices.

	---help---

	  Support for ADV7533 DSI to HDMI display bridge driver. The driver

	  controls the ADV7533 HW through the I2C interface and configures

	  the DSi input and HDMI output video format.
