| Analogix Display Port bridge bindings |
| |
| Required properties for dp-controller: |
| -compatible: |
| platform specific such as: |
| * "samsung,exynos5-dp" |
| * "rockchip,rk3288-dp" |
| * "rockchip,rk3399-edp" |
| -reg: |
| physical base address of the controller and length |
| of memory mapped region. |
| -interrupts: |
| interrupt combiner values. |
| -clocks: |
| from common clock binding: handle to dp clock. |
| -clock-names: |
| from common clock binding: Shall be "dp". |
| -interrupt-parent: |
| phandle to Interrupt combiner node. |
| -phys: |
| from general PHY binding: the phandle for the PHY device. |
| -phy-names: |
| from general PHY binding: Should be "dp". |
| |
| Optional properties for dp-controller: |
| -force-hpd: |
| Indicate driver need force hpd when hpd detect failed, this |
| is used for some eDP screen which don't have hpd signal. |
| -hpd-gpios: |
| Hotplug detect GPIO. |
| Indicates which GPIO should be used for hotplug detection |
| -port@[X]: SoC specific port nodes with endpoint definitions as defined |
| in Documentation/devicetree/bindings/media/video-interfaces.txt, |
| please refer to the SoC specific binding document: |
| * Documentation/devicetree/bindings/display/exynos/exynos_dp.txt |
| * Documentation/devicetree/bindings/display/rockchip/analogix_dp-rockchip.txt |
