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/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
|
||||
|
||||
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_clk",
|
||||
"pixel_clk",
|
||||
"iface_clk",
|
||||
"link_clk",
|
||||
"mdp_core_clk";
|
||||
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>;
|
||||
};
