| Rockchip RK3288 specific extensions to the Analogix Display Port |
| ================================ |
| |
| Required properties: |
| - compatible: "rockchip,rk3288-dp", |
| "rockchip,rk3399-edp"; |
| |
| - reg: physical base address of the controller and length |
| |
| - clocks: from common clock binding: handle to dp clock. |
| of memory mapped region. |
| |
| - clock-names: from common clock binding: |
| Required elements: "dp" "pclk" |
| |
| - resets: Must contain an entry for each entry in reset-names. |
| See ../reset/reset.txt for details. |
| |
| - pinctrl-names: Names corresponding to the chip hotplug pinctrl states. |
| - pinctrl-0: pin-control mode. should be <&edp_hpd> |
| |
| - reset-names: Must include the name "dp" |
| |
| - rockchip,grf: this soc should set GRF regs, so need get grf here. |
| |
| - ports: there are 2 port nodes with endpoint definitions as defined in |
| Documentation/devicetree/bindings/media/video-interfaces.txt. |
| Port 0: contained 2 endpoints, connecting to the output of vop. |
| Port 1: contained 1 endpoint, connecting to the input of panel. |
| |
| Optional property for different chips: |
| - clocks: from common clock binding: handle to grf_vio clock. |
| |
| - clock-names: from common clock binding: |
| Required elements: "grf" |
| |
| For the below properties, please refer to Analogix DP binding document: |
| * Documentation/devicetree/bindings/drm/bridge/analogix_dp.txt |
| - phys (required) |
| - phy-names (required) |
| - hpd-gpios (optional) |
| - force-hpd (optional) |
