Merge tag 'regulator-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This was a quite quiet release for regulators on the drivers front,
  but we do have two small but useful core improvements:

   - Improve handling of cases where DT platforms specify both DT and
     init_data based configuration for a single regulator.

   - A helper of_regulator_get_optional() to simplify writing generic
     bindings for regulator consumers in subsystems.

  There's also some YAML conversions for the DT bindings which are a big
  part of the diffstat"
