Merge tag 'actions-arm-dt-for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/afaerber/linux-actions into next/dt

Pull "Actions Semi ARM based SoC DT for v4.15" from Andreas Färber:

This updates the Guitar board DT with a clock node for the debug UART
and adds a new DT for the CubieBoard6.
It also updates the S500 DT with CPU power domains.

* tag 'actions-arm-dt-for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/afaerber/linux-actions:
  ARM: dts: owl-s500: Add CubieBoard6
  dt-bindings: arm: actions: Add CubieBoard6
  ARM: dts: owl-s500-guitar-bb-rev-b: Add fake uart3 clock
  ARM: dts: owl-s500: Set power domains for CPU2 and CPU3
