The original bitmask of 0x10 was incorrect and would result in a write

There are some unused registers in twl4030 at I2C address 0x49 and function
twl4030_49_nop_reg() is used to check accessibility of that registers. These
registers are written in decimal format but the values are correct in
hexadecimal format. (It can be checked few lines above the patched code -
these registers are marked as unused there.)
As a consequence three registers of audio submodule are treated as
inaccessible (preamplifier carkit right and both handsfree registers).

The pm8xxx-irq.c code is practically mandatory given that the
pm8921-core driver will WARN about it missing and the Kconfig
marks it as default y when a PM8xxx chips is enabled. The only
reason the file was split out was because we planned to support
other pm8xxx chips with different pm8xxx-core.c files. Now that
we have DT on ARM this isn't necessary because we should be able
to support all the ssbi based PM8xxx chips in one driver and one
file with no data bloat. Let's move this code into the only
driver that uses it right now (pm8921) so that it's always compiled when
needed. In the future we can rename pm8921-core.c to something
more generic.

new code is the 'production' variant code ID for DA9063.
This patch will remove the older variant code ID which matches the

it splits the revision code and correctly names it according to
