Subject: Re: [PATCH v2 0/4] add regmap_filelds and use it on Renesas Sound driver


Hi Mark

These patches are v2 of new regmap_filelds API on kernel.
                                         ~
It can care about multi port register offset via regmap.
 
0xAAAA + 0x40    -- port 0 --
                    regX
                    regY
                    regZ
0xAAAA + 0x80    -- port 1 --
                    regX
                    regY
                    regZ

This case, current API needs 2 (= port) x 3 (= regX/Y/Z) regmap_fileld,
but this new API can care about all port via 3 regmap_filelds with port ID.

I'm not sure that regmap_filelds is good naming or not.
Please let me know if you have good naming idea.

The difference between v1 <-> v2 is EXPORT_SYMBOL_GPL() naming
on regmap_filelds

these are based on below branchs
 regmap/for-next + asoc/for-next




Kuninori Morimoto (4):
      regmap: add regmap_field_update_bits()
      regmap: Add regmap_fields APIs
      ASoC: rsnd: gen: rsnd_gen_ops cares .probe and .remove
      ASoC: rsnd: use regmap instead of original register mapping method
