Merge tag 'regulator-spi-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc

Pull spi and regulator updates from Mark Brown:
 "At one point in the release cycle I managed to fat finger things and
  apply some SPI fixes onto a regulator branch and merge that into the
  SPI tree, then pull in a change shared with the MTD tree moving the
  Mediatek quadspi driver over to become the Mediatek spi-nor driver in
  the SPI tree.

  This has made a mess which I only just noticed while preparing this
  and I can't see a sensible way to unpick things due to other
  subsequent merge commits especially the pull from MTD so it looks like
  the most sensible thing to do is give up and combine the two pull
  requests.

  Fortunately both subsystems were fairly quiet this cycle, the
  highlights are:

  regulator:

   - Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869
     and Qualcomm PMI8994 and SMB208.

  SPI:

   - Lots of enhancements for spi-fsl-dspi, including XSPI mode support,
     from Vladimir Oltean.

   - Support for amlogic Meson G12A, IBM FSI, Mediatek spi-nor (moved
     from MTD), NXP i.MX8Mx, Rockchip PX30, RK3308 and RK3328, and
     Qualcomm Atheros AR934x/QCA95xx"
