It also needs a vendor prefix. The vendor prefix will be added in next time contribution, and this device seems has been used in former projects. Would you please to tell that whether I should inform the driver's author or add the binding document on my own ? > > > + reg = <0x20>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > These 2 are for child nodes, but you don't have any.
