The previous binding marked the below properties as required which was a driver requirement and not the device requirement so just drop them from the required list during the conversion. - clock-frequency - enable-gpios - reset-gpios Also drop the "clock-names" property as we have a single clock source for the sensor and the driver has been updated to drop the clk referencing by name.
