Hi Mark

These patches add new regmap_filelds API on kernel.
and use it on Renesas sound driver instead of original method.
It can care about multi port register offset via regmap.

0xAAAA + 0x40    -- port 0 --
0xAAAA + 0x80    -- port 1 --

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.

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
