|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible:
|
||
|
|
"rockchip,rk3066-hdmi";
|
||
|
|
- reg:
|
||
|
|
Physical base address and length of the controller's registers.
|
||
|
|
- clocks, clock-names:
|
||
|
|
Phandle to HDMI controller clock, name should be "hclk".
|
||
|
|
- interrupts:
|
||
|
|
HDMI interrupt number.
|
||
|
|
- power-domains:
|
||
|
|
Phandle to the RK3066_PD_VIO power domain.
|
||
|
|
- rockchip,grf:
|
||
|
|
This soc uses GRF regs to switch the HDMI TX input between vop0 and vop1.
|
||
|
|
- ports:
|
||
|
|
Contains one port node with two endpoints, numbered 0 and 1,
|
||
|
|
connected respectively to vop0 and vop1.
|
||
|
|
Contains one port node with one endpoint
|
||
|
|
connected to a hdmi-connector node.
|
||
|
|
- pinctrl-0, pinctrl-name:
|
||
|
|
Switch the iomux for the HPD/I2C pins to HDMI function.
|
||
|
|
|
||
|
