Merge tag 'pinctrl-v5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "It is pretty calm and chill in pin control for the moment. Just
  incremental development.

  There is an odd patch to the Super-H architecture, it's coming from
  the maintainers so should be fine.

  Summary:

  New drivers:
   - Bitmain BM1880 pin controller
   - Mediatek MT8516
   - Cirrus Logich Lochnagar PMIC pins

  Updates:
   - Incremental development on Renesas SH-PFC
   - Incremental development on Intel pin controller and some particular
     updates for Cedarfork.
   - Pin configuration support in Allwinner SunXi drivers
   - Suspend/resume support in the NXP/Freescale i.MX8MQ driver
   - Support for more packaging of the ST Micro STM32"
