Merge tag 'regmap-v5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap 

Pull regmap updates from Mark Brown:
 "Quite a busy release for regmap, mostly support for new features
  useful on fairly small subsets of devices. The user visible features
  are:

   - A new API for registering large numbers of regmap fields at once.

   - Support for Intel AVMM buses connected via SPI.

   - Support for 12/20 address/value layouts.

   - Support for yet another scheme for acknowledging interrupts used on
     some Qualcomm devices"

  regmap: debugfs: use semicolons rather than commas to separate statements
  regmap: debugfs: Fix more error path regressions
  regmap: Add support for 12/20 register formatting
  regmap: Add can_sleep configuration option
