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>;
