[Sebastian Hesselbarth]

Hi Arnd, Kevin, Olof,

this is Marvell Berlin SoC changes for v4.2 selecting MFD_SYSCON by
default for Berlin SoCs as now vital System/Chip controller drivers
depend on it.

[GIT PULL] ARM: berlin: DT changes for v4.2 (round 1)

[Sebastian Hesselbarth]

Hi Arnd, Kevin, Olof,

this is Marvell Berlin SoC DT for v4.2 including:
- GPLv2/X11 dual-licensing of DT files,
- a note about currently unstable DT bindings as we struggle to get
  DT bindings right in the first place with limited documentation available,
- Rework of System/Chip Controller binding documentation and nodes to
  simple-mfd.

Please pull.

I'm a bit confused by this. Are you sure that it's ok to apply this branch
by itself without introducing regressions or bisection problems?

It's fine to have unstable bindings for a while as you are ramping up,
but that requires a lot more care on your side regarding the order in
which you send the patches. I have received three pull requests from
you that are all based on -rc1, and from a brief look it seems like
they are interdependent, which would not be ok.

Ach, dammit. You are right, the patches reworking chip/sys ctrl nodes
are currently un-bisectable. I do have Acked-by's from subsystem
maintainers, so I guess I'll have to squash the DT changes with the
driver changes.

Yes, the rework of the drivers and the corresponding DT changes
depend on each other. Sorry for the confusion.
