fdd9ef3dceSoundWire MBQ register maps typically contain a variety of register sizes, which doesn't map ideally to the regmap abstraction which expects register maps to have a consistent size. Currently the MBQ register map only allows 16-bit registers to be defined, however this leads to complex CODEC driver implementations with an 8-bit register map and a 16-bit MBQ, every control will then have a custom get and put handler that allows them to access different register maps. Further more 32-bit MBQ quantities are not currently supported. Add support for additional MBQ sizes and to avoid the complexity of multiple register maps treat the val_size as a maximum size for the register map. Within the regmap use an ancillary callback to determine how many bytes to actually read/write to the hardware for a specific register. In the case that no callback is defined the behaviour defaults back to the existing behaviour of a fixed size register map.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
