| Rockchip specific extensions for rk3066 HDMI |
| ============================================ |
| |
| 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. |
| |
