This patch set aims to fix issues in wm8962 codec driver related to regmap, currently any attempt to read from ALC Coefficient register will fail when wm8962 is in suspend mode. As ALC2 register is volatile register, it can't be read when cache_only flag is set.
Another issue is, if wm8962's regulator is set to 'regulator-always-on' mode, then after wm8962 is resumed from suspend, wm8962 codec is reset, but cache_dirty flag isn't set, this cause difference between actual wm8962 HW and regmap cache.
Changeset: -------------- v1 -> v2 * removed comment before regcache_mark_dirty
Jiada Wang (2): ASoC: WM8962: mark cache_dirty flag after software reset in pm_resume ASoC: Codec: wm8962: declare ALC Coefficients as 4 separate registers
