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>;
};
