This supply need not go to the touchscreen itself as long as it allows the main board to make signals compatible with what the touchscreen is expecting for its IO rails. goodix,no-reset-during-suspend: description: Set this to true to enforce the driver to not assert the reset GPIO during suspend. Due to potential touchscreen hardware flaw, back-powering could happen in suspend if the power supply is on and with active-low reset GPIO asserted. This property is used to avoid the back-powering issue. type: boolean required: - compatible - reg - interrupts - reset-gpios - vdd-supply additionalProperties: false examples: - | #include <dt-bindings/clock/qcom,rpmh.h> #include <dt-bindings/gpio/gpio.h> #include <dt-bindings/interrupt-controller/irq.h> i2c { #address-cells = <1>; #size-cells = <0>; ap_ts: touchscreen@5d { compatible = "goodix,gt7375p"; reg = <0x5d>; interrupt-parent = <&tlmm>; interrupts = <9 IRQ_TYPE_LEVEL_LOW>; reset-gpios = <&tlmm 8 GPIO_ACTIVE_LOW>; vdd-supply = <&pp3300_ts>; }; };
