Raspberry Pi power domain driver



Required properties:



- compatible:		Should be "raspberrypi,bcm2835-power".

- firmware:		Reference to the RPi firmware device node.

- #power-domain-cells:	Should be <1>, we providing multiple power domains.



The valid defines for power domain are:



 RPI_POWER_DOMAIN_I2C0

 RPI_POWER_DOMAIN_I2C1

 RPI_POWER_DOMAIN_I2C2

 RPI_POWER_DOMAIN_VIDEO_SCALER

 RPI_POWER_DOMAIN_VPU1

 RPI_POWER_DOMAIN_HDMI

 RPI_POWER_DOMAIN_USB

 RPI_POWER_DOMAIN_VEC

 RPI_POWER_DOMAIN_JPEG

 RPI_POWER_DOMAIN_H264

 RPI_POWER_DOMAIN_V3D

 RPI_POWER_DOMAIN_ISP

 RPI_POWER_DOMAIN_UNICAM0

 RPI_POWER_DOMAIN_UNICAM1

 RPI_POWER_DOMAIN_CCP2RX

 RPI_POWER_DOMAIN_CSI2

 RPI_POWER_DOMAIN_CPI

 RPI_POWER_DOMAIN_DSI0

 RPI_POWER_DOMAIN_DSI1

 RPI_POWER_DOMAIN_TRANSPOSER

 RPI_POWER_DOMAIN_CCP2TX

 RPI_POWER_DOMAIN_CDP

 RPI_POWER_DOMAIN_ARM



Example:



power: power {

	compatible = "raspberrypi,bcm2835-power";

	firmware = <&firmware>;

	#power-domain-cells = <1>;

};



Example for using power domain:



&usb {

       power-domains = <&power RPI_POWER_DOMAIN_USB>;

};
