Merge tag 'regulator-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This release is almost all drivers, there's some small improvements in
  the core but otherwise everything is updates to drivers, mostly the
  addition of new ones.

  There's also a bunch of changes pulled in from the MFD subsystem as
  dependencies, Rockchip and TI core MFD code that the regulator drivers
  depend on.

  I've also yet again managed to put a SPI commit in the regulator tree,
  I don't know what it is about those two trees (this for
  spi-geni-qcom).

  Summary:

   - Support for Renesas RAA215300, Rockchip RK808, Texas Instruments
     TPS6594 and TPS6287x, and X-Powers AXP15060 and AXP313a"
