Merge tag 'regulator-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "The big change in this release is the addition of Rust bindings from
  Daniel Almeida, allowing fairly basic consumer use with support for
  enable and voltage setting operations. This should be good for the
  vast majority of consumers.

  Otherwise it's been quite quiet, a few new devices supported, plus
  some cleanups and fixes.

  Summary:

   - Basic Rust bindings

   - A fix for making large voltage changes on regulators where we limit
     the size of voltage change we will do in one step, previously we
     just got as close as we could in one step

   - Cleanups of our usage of the PM autosuspend functions, this pulls
     in some PM core changes on a shared tag

   - Mode setting support for PCA9450

   - Support for Mediatek MT6893 and MT8196 DVFSRC, Qualcomm PM7550 and
     PMR735B, Raspberry Pi displays and TI TPS652G1

  The TI driver pulls in the MFD portion of the support for the device
  and the pinctrl driver which was in the same tag"
