Qualcomm Technologies Inc. adreno/snapdragon eDP output
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/clock/clock-bindings.txt for details. - clock-names: the following clocks are required:
- “core”
- “iface”
- “mdp_core”
- “pixel”
- “link”
- #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
