| Required properties |
| - compatible : Must be "qcom,mdss-edp". |
| - reg : Offset and length of the register set for the |
| device. |
| - reg-names : Names to refer to register sets related to this |
| device |
| - vdda-supply : Phandle for vdd regulator device node. |
| - gpio-panel-en : GPIO for supplying power to panel and backlight |
| driver. |
| - qcom,panel-lpg-channel : LPG channel for backlight. |

| Example: |
| mdss_edp: qcom,mdss_edp@fd923400 { |
| compatible = "qcom,mdss-edp"; |
| reg = <0xfd923400 0x700>, |
| <0xfd8c2000 0x1000>; |
| reg-names = "edp_base", "mmss_cc_base"; |
| vdda-supply = <&pm8941_l12>; |
| gpio-panel-en = <&msmgpio 58 0>; |
