Pervasive Displays RePaper branded e-ink displays



Required properties:

- compatible:		"pervasive,e1144cs021" for 1.44" display

			"pervasive,e1190cs021" for 1.9" display

			"pervasive,e2200cs021" for 2.0" display

			"pervasive,e2271cs021" for 2.7" display



- panel-on-gpios:	Timing controller power control

- discharge-gpios:	Discharge control

- reset-gpios:		RESET pin

- busy-gpios:		BUSY pin



Required property for e2271cs021:

- border-gpios:		Border control



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 property:

- pervasive,thermal-zone:	name of thermometer's thermal zone



Example:



	display_temp: lm75@48 {

		compatible = "lm75b";

		reg = <0x48>;

		#thermal-sensor-cells = <0>;

	};



	thermal-zones {

		display {

			polling-delay-passive = <0>;

			polling-delay = <0>;

			thermal-sensors = <&display_temp>;

		};

	};



	papirus27@0{

		compatible = "pervasive,e2271cs021";

		reg = <0>;



		spi-max-frequency = <8000000>;



		panel-on-gpios = <&gpio 23 0>;

		border-gpios = <&gpio 14 0>;

		discharge-gpios = <&gpio 15 0>;

		reset-gpios = <&gpio 24 0>;

		busy-gpios = <&gpio 25 0>;



		pervasive,thermal-zone = "display";

	};
