The Samsung S6SY761 touchscreen bindings expect AVDD regulator which is missing in the Sony Xperia PDX225 DTS. There is however pinctrl setting for in the touchscreen device node with similar name: "avdd", so assume author wanted to control a fixed regulator with a GPIO. This fixes dtbs_check warning: sm6375-sony-xperia-murray-pdx225.dtb: touchscreen@48: 'avdd-supply' is a required property Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- Not tested on HW.
