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.
Example:
mdss_edp: qcom,mdss_edp@fd923400 {
compatible = "qcom,mdss-edp";
reg-names =
"edp",
"pll_base";
reg = <0xfd923400 0x700>,
<0xfd923a00 0xd4>;
interrupt-parent = <&mdss_mdp>;
interrupts = <12 0>;
power-domains = <&mmcc MDSS_GDSC>;
clock-names =
"core",
"pixel",
"iface",
"link",
"mdp_core";
clocks =
<&mmcc MDSS_EDPAUX_CLK>,
<&mmcc MDSS_EDPPIXEL_CLK>,
<&mmcc MDSS_AHB_CLK>,
<&mmcc MDSS_EDPLINK_CLK>,
<&mmcc MDSS_MDP_CLK>;
#clock-cells = <1>;
vdda-supply = <&pma8084_l12>;
lvl-vdd-supply = <&lvl_vreg>;
panel-en-gpios = <&tlmm 137 0>;
panel-hpd-gpios = <&tlmm 103 0>;
