Merge tag 'regmap-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "This is quite a busy release for regmap with two substantial features
  being added:

    - Support for register maps Soundwire 1.2 multi-byte operations,
      allowing atomic support for registers larger than a single byte.

    - Support for relaxed I/O without barriers in MMIO regmaps, allowing
      them to be used efficiently on systems where default MMIO
      operations include barriers.

  There was also an addition and revert of use of the new Soundwire
  support for RT715 due to build issues with the driver built in, my
  tests only covered building it as a module, the patch wasn't just
  dropped as it had already been merged elsewhere"

* tag 'regmap-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
  ASoC: rt715: Fix build
  regmap: sdw: add required header files
  regmap: Remove duplicate `type` field from regmap `regcache_sync` trace event
  regmap: Fix order of regmap write log
  regmap: mmio: add config option to allow relaxed MMIO accesses
