+panel interface for eDP/lvds panels
+
+Required properties:
+ - compatible: "panel-lvds"
+
+Optional properties:
+ -lcd-enable-gpios:
+ panel LCD poweron GPIO.
+ Indicates which GPIO needs to be powered up as output
+ to powerup/enable the switch to the LCD panel.
+ -backlight-enable-gpios:
+ panel LED enable GPIO.
+ Indicates which GPIO needs to be powered up as output
+ to enable the backlight.
+ -panel-prepare-delay:
+ delay value in ms required for panel_prepare process
+ Delay in ms needed for the panel LCD unit to
+ powerup completely.
+ ex: delay needed till eDP panel throws HPD.
+ delay needed so that we cans tart reading edid.
+ -panel-enable-delay:
+ delay value in ms required for panel_enable process
+ Delay in ms needed for the panel backlight/LED unit
+ to powerup, and delay needed between video_enable and
+ backlight_enable.
+ -panel-disable-delay:
+ delay value in ms required for panel_disable process
+ Delay in ms needed for the panel backlight/LED unit
+ powerdown, and delay needed between backlight_disable
+ and video_disable.
+ -panel-unprepare-delay:
+ delay value in ms required for panel_post_disable process
+ Delay in ms needed for the panel LCD unit to
+ to powerdown completely, and the minimum delay needed
+ before powering it on again.
+ -panel-width-mm: physical panel width [mm]
+ -panel-height-mm: physical panel height [mm]
+
+Example:
+
+ panel-lvds {
+ compatible = "panel-lvds";
+ backlight-enable-gpios = <&gpx3 0 0>;
+ panel-prepare-delay = <40>;
+ panel-enable-delay = <20>;
+ panel-disable-delay = <20>;
+ panel-unprepare-delay = <30>;
+ panel-width-mm = <256>;
+ panel-height-mm = <144>;
+ };
