Will add this change in next version (v6) of the patch-set. Snippet will look as mentioned below. + - if: + properties: + compatible: + contains: + enum: + - samsung,exynosautov920-usbdrd-phy + then: + required: + - dvdd075-usb20-supply + - vdd18-usb20-supply + - vdd33-usb20-supply + + else: + properties: + dvdd075-usb20-supply: false + vdd18-usb20-supply: false Thank you.
