The 16bit COEF read/write is pretty standard for many codecs, and they can be cached in most cases -- more importantly, they need to be restored at resume. For making this easier, add the cache support to regmap. If the codec driver wants to cache the COEF access, set codec->cache_coef flag and issue AC_VERB_GET_PROC_COEF with the coef index in LSB 8 bits. Signed-off-by: Takashi Iwai <tiwai@suse.de> |
