Merge tag 'regulator-v6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is a very quiet release for regulator, almost all the changes are
  new drivers but we do also have some improvements for the Rust
  bindings.

   - Additional APIs added to the Rust bindings

   - Support for Maxim MAX77838, NXP PF0900 and PF5300, Richtek RT5133
     and SpacemiT P1"
