You have dependency otherwise. Also this points to issue of mixing nodes with and without unit address. I think i2c children should be under some sort of "i2c" bus node. Please propose entire realtek,rtl9302c-switch binding with the I2C. It's very confusing to see it partial. Best regards, Krzysztof
