Lars-Peter Clausen 61cddc57dc regmap: Fix cache defaults initialization from raw cache defaults ... Currently registers with a value of 0 are ignored when initializing the register defaults from raw defaults. This worked in the past, because registers without a explicit default were assumed to have a default value of 0. This was changed in commit b03622a8 ("regmap: Ensure rbtree syncs registers set to zero properly"). As a result registers, which have a raw default value of 0 are now assumed to have no default. This again can result in unnecessary writes when syncing the cache. It will also result in unnecessary reads for e.g. the first update operation. In the case where readback is not possible this will even let the update operation fail, if the register has not been written to before. So this patch removes the check. Instead it adds a check to ignore raw defaults for registers which are volatile, since those registers are not cached.
