Merge tag 'v4.16-next-soc' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux into next/drivers

Pull "ARM: mediatek: updates for soc drivers for v4.16-next" from Matthias Brugger:

scpsy:
- mt2712: update power domains to reflect design changes in the SoC
- fix initialisation of power subdomains
- add support for mt7623a SoC
- use defines for mt2701 bus protection mask

* tag 'v4.16-next-soc' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux:
  soc: mediatek: update power domain data of MT2712
  dt-bindings: soc: update MT2712 power dt-bindings
  soc: mediatek: fix the mistaken pointer accessed when subdomains are added
  soc: mediatek: add SCPSYS power domain driver for MediaTek MT7623A SoC
  soc: mediatek: avoid hardcoded value with bus_prot_mask
  dt-bindings: soc: add header files required for MT7623A SCPSYS dt-binding
  dt-bindings: soc: add SCPSYS binding for MT7623 and MT7623A SoC
