Merge tag 'regulator-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is a relatively busy release for the regulator API, as well as a
  good collection of new drivers we've got a little bit of core work and
  a bunch of cleanup throughout the subsystem:

   - Support for propagating undervoltage events to child regulators

   - Undo enables done on supplies when setting enabling regulators via
     constraints fails

   - Pull in some gpiolib changes adding support for shared GPIOs to the
     gpiolib core, using them to replace the open coded variant of this
     that we've had in the regulator API for a long time

   - Support for Fitipower FP9931 and JD9330, Mediatek MT6316, MT6363
     and MT6373, NXP PF1550 and Qualcomm PMH01XX and PMCX0102

  The PF1550 support was originally going to go via the MFD tree but
  Krzysztof's cleanup work overlapped with it so I pulled in Lee's
  signed tag with support for the device"
