  regmap: reg_default_cb for flat cache defaults (2026-01-28 03:48:12 +0000)

----------------------------------------------------------------
regmap: Updates for v7.0

The main change here is the implementation of a mechanism for generating
register defaults via a callback rather than with a table in the driver.
This is useful for devices where there are large ranges of registers
with the same or generateable values, it allows us to have a small
amount of code instead of a larger amount of default data.
