+Ilitek ILI9486 display panels
+
+This binding is for display panels using an Ilitek ILI9486 controller in SPI
+mode.
+
+Required properties:
+- compatible:   "ozzmaker,piscreen", "waveshare,rpi-lcd-35", "ilitek,ili9486"
+- dc-gpios:     D/C pin
+- reset-gpios:  Reset pin
+
+The node for this driver must be a child node of a SPI controller, hence
+all mandatory properties described in ../spi/spi-bus.txt must be specified.
+
+Optional properties:
+- rotation:     panel rotation in degrees counter clockwise (0,90,180,270)
+- backlight:    phandle of the backlight device attached to the panel
+
+Example:
+        display at 0{
+                compatible = "ozzmaker,piscreen", "waveshare,rpi-lcd-35", "ilitek,ili9486";
+                reg = <0>;
+                spi-max-frequency = <32000000>;
+                dc-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
+                reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
+                rotation = <180>;
+                backlight = <&backlight>;
+        };
