Hi!

Actually... This is quite impressive ammount of code to
zero-initialize few registers. Could the regmap be told to set the
range to zero, or use loops to reduce ammount of code?
I am not aware of any regmap calls that will set a range of registers to a
certain value.

Well it depends on where we want to create the default cache values.

Either we run through a for..loop during driver probe and delay device start
up or we keep the simple arrays and increase the driver total size.
for loop will be better.

Plus, REGCACHE_RBTREE is very likely overkill.

Well if I eliminate the reg_cache then I can eliminate the defaults too.
