+Sitronix ST7735R display panels
+
+This binding is for display panels using a Sitronix ST7735R controller in SPI
+mode.
+
+Required properties:
+- compatible:  "sitronix,st7735r-jd-t18003-t01"
+- dc-gpios:    Display data/command selection (D/CX)
+- reset-gpios: Reset signal (RSTX)
+
+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:
+
+       backlight: backlight {
+               compatible = "gpio-backlight";
+               gpios = <&gpio 44 GPIO_ACTIVE_HIGH>;
+       }
+
+       ...
+
+       display@0{
+               compatible = "sitronix,st7735r-jd-t18003-t01";
+               reg = <0>;
+               spi-max-frequency = <32000000>;
+               dc-gpios = <&gpio 43 GPIO_ACTIVE_HIGH>;
+               reset-gpios = <&gpio 80 GPIO_ACTIVE_HIGH>;
+               rotation = <270>;
+               backlight = &backlight;
+       };
