Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
This series is the next step of adding SDCA support. Here we add
helper functions to allow drivers to easily use the SDCA DisCo
information to create a register map for the device.
The basic idea here is the code takes the list of SDCA controls parsed
from DisCo and uses primarily the Access Mode to determine if the
register should be marked as readable/writable etc. Further more
some additional concepts such as DisCo Constants and Defaults are
handled. There is some potential confusion, as DisCo Constants are
handled as an entry in the regmap defaults table, whereas a DisCo
Default is simply handled as a write to the register. Alas the naming
confusion is an unavoidable result of the slight impedance mismatch
between the two systems.
The 'msk' variable has no initialization:
sound/soc/mediatek/mt8188/mt8188-dai-dmic.c:311:4: error: variable 'msk' is uninitialized when used here [-Werror,-Wuninitialized]
311 | msk |= PWR2_TOP_CON1_DMIC_FIFO_SOFT_RST_EN(i);
| ^~~
Set it to zero before the loop.

The concept of an SDCA default value differs slightly from the regmap
usage of the term. An SDCA default is a value that is parsed from DisCo
and then written out to the hardware if no user value has superceded
it. Add a helper function that will iterate through all the SDCA
Controls and write out any default values. After these have been written
out once they will exist in the cache and that will take care of any
user values superceeding them. The code here also writes out any
Controls with a fixed value as there is only one available value for
these Controls there is no point in allowing the user to select them,
simply treat them similarly to a default.

Add helpers to parse the DisCo Constant values from ACPI and populate an
array of reg_defaults with these. This will allow drivers to access
these ACPI specified values through the same interface as other
registers that are physically present on the device, using the regmap
cache.

Add helper functions that SDCA drivers can use to calculate the
properties of SDCA Controls (registers) specified through DisCo.
Most of these are fairly obvious from the SDCA Access Modes.
DisCo Constants, values which are specified in the ACPI rather than on
the device, are handled as unreadable and unwritable registers. The
intention is these will be populated in the register defaults table
allowing drivers to read them normally. This means the drivers can be
agnostic as to which values are DisCo Constants.
Finally, support for SDCA Dual Ranked Controls is currently limited
here, at the moment the current value will be used directly. Writing
the current value directly is valid as per the specification
although the synchronicity of updates across multiple registers is
lost. Support for this will probably need to be added later. But its a
fairly hard problem and doesn't need to be solved immediately.

The defaults array in regcache must be sorted into ascending register
address order, because binary search is used to locate values in
the array. Add a helper to sort the register defaults array which
can be useful for systems that dynamically create a defaults array
based on external information.
