[GIT PULL] rockchip clock changes for 4.7 part 1

[Heiko Stuebner]

Hi Mike, Stephen,

please find below clock changes for 4.7. As the tag explains it is mainly
the rk3399 support + necessary plumbing.

So if it looks ok, please pull.


Thanks
Heiko

The following changes since commit f55532a0c0b8bb6148f4e07853b876ef73bc69ca:

  clk: rockchip: add clock controller for the RK3399 (2016-03-28 14:57:07 +0200)

----------------------------------------------------------------
This is first big chunk of Rockchip clock-related changes for 4.7.

Main change is probably the added support for the new rk3399 soc
and necessary infrastructure changes surrounding it.

The biggest chunk is probably that clock code is now able to
handle multiple clock providers in one system, as the rk3399
has two of those. A general one and another smaller one in a
separate power domain. The rk3399 also uses another new pll type.
Thankfully it just fits nicely into our current structure.
It also needs some parts like the cpuclk mux parameters to be
a bit more flexible and an new fractional divider subtype without
gate.

Apart from this big change we have some more fixes and removal
of forgotten variables.

Pulled into clk-next.

BUT, this has some checkpatch annoyances, mostly spaces before
tabs in the DT headers. For example:

WARNING: please, no space before tabs
#162: FILE: include/dt-bindings/clock/rk3399-cru.h:139:
+#define FCLK_CM0S ^I^I^I190$

WARNING: please, no space before tabs
#233: FILE: include/dt-bindings/clock/rk3399-cru.h:210:
+#define ACLK_PERF_CORE_L ^I^I260$

Please send another patch to fix those or do it in another pull,
whatever works for you.

sorry about that. Will send a fixup hopefully today or tomorrow.
