V5: No Change
V4: No Change
V3: Removed mintems at the request of Krzysztof and add his
reviewed-by
V2: I (Adam) tried to help move this along, so I took Lucas' patch
and attempted to apply fixes based on feedback. I don't have
all the history, so apologies for that.
Added phy-cells to the required list and fixed an error due
to the word 'binding' being in the title.
