+Good Display/Waveshare e-ink displays
+
+Required properties:
+- compatible: "gooddisplay,wfi0190cz22" for 2.7" b/w/red displays,
+ replace part number for other displays.
+ Use "gooddisplay,generic_epaper" to manually configure
+ the display's resolution etc.
+
+- dc-gpios: Data Command
+- reset-gpios: Reset pin
+- busy-gpios: Busy pin
+- spi-speed-hz SPI baud rate to use to when talking to the display
+
+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.
+
+Example:
+
+ epaper@0{
+ compatible = "gooddisplay,gdew042z15";
+ reg = <0>;
+ spi-speed-hz = <1000000>;
+ spi-max-frequency = <6000000>;
+ dc-gpios = <&gpio 25 GPIO_ACTIVE_HIGH>;
+ reset-gpios = <&gpio 17 GPIO_ACTIVE_HIGH>;
+ busy-gpios = <&gpio 24 GPIO_ACTIVE_LOW>;
+ };
