Merge tag 'regulator-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator 

Pull regulator updates from Mark Brown:
 "The main updates for this release are around monitoring of regulators,
  largely for error handling purposes. We allow the stream of regulator
  events to be seen by userspace as netlink events and allow system
  integrators to describe individual regulators as system critical with
  information on how long the system is expected to last on error. The
  system level error handling is very much about best effort problem
  mitigation rather than providing something fully robust, the initial
  drive was to provide a mechanism for trying to avoid initiating any
  new writes to flash once we notice the power going out.

  Otherwise it's very quiet, mainly several new Qualcomm devices.

   - Support for marking regulators as system critical and providing
     information on how long the system might last with those regulators
     in a failure state, hooked into the existing critical shutdown
     error handling.

   - Optional support for generating netlink events for events, there
     are use cases for system monitoring UIs and error handling.

   - A command line option to leave unused controllable regulators
     enabled, useful for debugging. We already only disable regulators
     we were explicitly given permission to control.

   - Support for Quacomm MP5496, PM8010 and PM8937"
