|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible:
|
||
|
|
* "qcom,mdss-edp"
|
||
|
|
- reg: Physical base address and length of the registers of controller and PLL
|
||
|
|
- reg-names: The names of register regions. The following regions are required:
|
||
|
|
* "edp"
|
||
|
|
* "pll_base"
|
||
|
|
- interrupts: The interrupt signal from the eDP block.
|
||
|
|
- power-domains: Should be <&mmcc MDSS_GDSC>.
|
||
|
|
- clocks: device clocks
|
||
|
|
See Documentation/devicetree/bindings/clocks/clock-bindings.txt for details.
|
||
|
|
- clock-names: the following clocks are required:
|
||
|
|
* "core_clk"
|
||
|
|
* "iface_clk"
|
||
|
|
* "mdp_core_clk"
|
||
|
|
* "pixel_clk"
|
||
|
|
* "link_clk"
|
||
|
|
- #clock-cells: The value should be 1.
|
||
|
|
- vdda-supply: phandle to vdda regulator device node
|
||
|
|
- lvl-vdd-supply: phandle to regulator device node which is used to supply power
|
||
|
|
to HPD receiving chip
|
||
|
|
- panel-en-gpios: GPIO pin to supply power to panel.
|
||
|
|
- panel-hpd-gpios: GPIO pin used for eDP hpd.
|
||
|
|
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- interrupt-parent: phandle to the MDP block if the interrupt signal is routed
|
||
|
|
through MDP block
|
||
|
|
|
||
|
|
