| -- qcom,supply-post-off-sleep: time to sleep (ms) after turning off |
| - qcom,panel-supply-entries: A node that lists the elements of the supply used to |
| power the DSI panel. There can be more than one instance |
| of this binding, in which case the entry would be appended |
| with the supply entry index. For a detailed description of |
| fields in the supply entry, refer to the qcom,ctrl-supply-entries |
| binding above. |
| - qcom,core-supply-entries: A node that lists the elements of the supply used to |
| power the DSI core. There can be more than one instance |
| of this binding, in which case the entry would be appended |
| with the supply entry index. For a detailed description of |
| fields in the supply entry, refer to the qcom,ctrl-supply-entries |
| binding above. |
| - qcom,platform-enable-gpio: Specifies the panel lcd/display enable gpio. |
| - qcom,platform-reset-gpio: Specifies the panel reset gpio. |
| - qcom,platform-te-gpio: Specifies the gpio used for TE. |
| - qcom,platform-bklight-en-gpio: Specifies the gpio used to enable display back-light |
| - qcom,platform-mode-gpio: Select video/command mode of panel through gpio when it supports |
| both modes. |
| - pinctrl-names: List of names to assign mdss pin states defined in pinctrl device node |
| Refer to pinctrl-bindings.txt |
| - pinctrl-<0..n>: Lists phandles each pointing to the pin configuration node within a pin |
| controller. These pin configurations are installed in the pinctrl |
| device node. Refer to pinctrl-bindings.txt |
| - qcom,regulator-ldo-mode: Boolean to enable ldo mode for the dsi phy regulator |
| - qcom,dsi-panel-bias-vreg: Boolean to enable control of panel bias regulator |
| - qcom,mmss-ulp-clamp-ctrl-offset: Specifies the offset for dsi ulps clamp control register. |
| - qcom,mmss-phyreset-ctrl-offset: Specifies the offset for dsi phy reset control register. |
