[PATCH v2 00/10] Marvell Berlin full clock support

this is v2 of the Berlin SoC clock driver [1] but with a reworked DT
binding as requested [2]. We decided to not even try to split up the chip
control registers that deal with pinmux, padmux, clock, reset, and evil
stuff we haven't even looked at. Instead we keep a single node that clock
driver will remap early, while proper platform_drivers use a regmap
instead. Although clock and other drivers share the same register range,
they use individual registers exclusively.

There are some functional fixes in the single clock drivers, I noticed
while retesting each individial driver. There will be more to fixup but
without any drivers actually using the clocks, it is hard to tell what
isn't working now.

Anyway, the current binding should match what you requested and having
a clock driver for v3.16 will really be a huge benefit for us to work
on more driver support.

If you are fine with it, please take patches 2-7 and I'll pick up
1,8-10 in berlin branch.
