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/display/bridge/analogix_dp.txt
|
||||
- phys (required)
|
||||
- phy-names (required)
|
||||
- hpd-gpios (optional)
|
||||
- force-hpd (optional)
