- #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>;
