Subject: [PATCH v2 0/5] BCM2835 PM driver (MFD version)

Guenter Roeck and Stefan Wahren both wanted a MFD-style driver to
cover the PM node that lets WDT and soc/bcm2835-power both attach to
it.  I think this is an ugly solution because it bloats this feature
addition by 25% more lines for all the boilerplate, but here it is.
Tested with V3D powering on, haven't double-checked the reset
controller.

Eric Anholt (5):
  dt-bindings: soc: Add a new binding for the BCM2835 PM node.
  bcm2835-pm: Move bcm2835-watchdog's DT probe to an MFD.
  soc: bcm: bcm2835-pm: Add support for power domains under a new
    binding.
  ARM: bcm283x: Extend the WDT DT node out to cover the whole PM block.
  ARM: bcm283x: Switch V3D over to using the PM driver instead of
    firmware.
