Merge tag 'regmap-offload-update-bits' into regmap-next
regmap: Allow buses to provide a custom update_bits() operation
Some buses provide a native _update_bits() operation which for uncached
registers is faster than doing a read/modify/write cycle as it is a
single bus transaction. Add support for implementing this to regmap.
