media: platform: Altek AL6100 driver release 



This change adds the Altek mini isp driver for sdm845 robotics.
Altek mini isp driver is to process the depth data from dual
IR camera sensor. This will be used on sdm845 robotics.

Altek al6100 depth chip driver(spi/I2c)



Description:



The al6100 is a mini isp chip which is to process

the dual IR raw images from IR camera sensor to be

depth data. It has own firmware. It can connect to

two IR camera sensors via internal mipi port(Rx0/Rx1).

The input of this chip is the IR raw image from

the two IR camera sensors. The Tx0/Tx1 on chip can

connect to AP side and output depth data and IR images

to AP.



Required properties:

 - compatible: Should be "altek,isp"(with spi)/

   "altek,i2c_slave"(with i2c)/"altek,i2c_top"(with i2c)

   for al6100 depth chip driver

 - irq-gpios: a gpio for spi/I2c interrupt



Optional properties:

 - vcc1-gpios: If present, specifies a gpio for power on

   al6100 depth chip

 - wp-gpios: If present, specifies a gpio for control

   eeprom write protected pin

 - reset-gpios: If present, specifies a gpio for reset

   al6100 depth chip



Example:

	(spi)

	&spi_8 {

		mini_isp@0 {

			compatible = "altek,isp";

			reg = <0>;

			spi-max-frequency = <50000000>;

			spi-cpol;

			spi-cpha;

			vcc-supply = <&pm8953_s3>;

			reset-gpios = <&tlmm 33 0x00>;

			irq-gpios = <&tlmm 35 0x00>;

			vcc1-gpios = <&tlmm 38 0x00>;

			wp-gpios = <&tlmm 52 0x00>;

			vcc2-gpios = <&tlmm 63 0x00>;

			status = "ok";

		};

	};



	(I2c)

	i2c_slave@11 {

		compatible = "altek,i2c_slave";

		reg = <0x4b>;	/* for Pure Bypass */

		reg = <0x11>;

		status = "disabled";	/* use SPI instead */

	};



	i2c_top@77 {

		compatible = "altek,i2c_top";

		reg = <0x77>;

		vcc-supply = <&pm8953_s3>;

		reset-gpios = <&tlmm 33 0x00>;

		irq-gpios = <&tlmm 35 0x00>;

		vcc1-gpios = <&tlmm 38 0x00>;

		wp-gpios = <&tlmm 52 0x00>;

		vcc2-gpios = <&tlmm 63 0x00>;

		status = "disabled";	/* use SPI instead */

	};
