This patchset adds support for the gated clock controller found on most
MIPS based Broadcom BCM63XX SoCs.

The MIPS based BCM63XX SoCs have very little in common with the ARM
based ones, so a separate driver is necessary.

It's a simple register based controller, with one bit per clock, active
high.

Since BCM63XX/MIPS runs in big endian mode, the driver depends on the
series "clk: make register endianness a run-time property", or more
specifically on patch 3, "clk: gate: add explicit big endian support".

Based on the clk-next branch.

Jonas Gorski (3):
  devicetree: document the BCM63XX gated clock bindings
  clk: add BCM63XX gated clock controller driver

Now that we have a driver for the clock controller, add nodes to allow
devices to make use of it.

We could always add 6348/6338 to that list later one.

That's the plan*. But currently neither one is supported by
BMIPS_GENERIC, which was my starting point. And making BCM63XX use the
driver is ... complicated, due to (important) consumers not being
platform drivers (the MPI/PCIe controller codes). And they can't be
just converted to platform drivers, as they should then be non-legacy
PCI controller drivers, so a full rewrite is needed.

So let's stick with BMIPS_GENERIC first, else we never get anything
done ;-). In the end BCM63XX should go away anyway, once BMIPS_GENERIC
has reached feature parity.


Regards
Jonas

* if it even makes sense, as these are quite old, and systems will
quite struggle running a modern kernel/OS.

I'd have ordered this patch after the #2 of this series, or eventually
squashed both together. It is weird to document an unexistant feature
then implement it, while the opposite looks more natural.
(If you agree, maybe Paul can invert those when applying this series).

Anyway:

You are documenting hardware, not a driver/feature. :-)

The binding is supposed to be a separate patch [1]. The natural order
is to first describe the hardware (with the binding documentation),
then add the actual driver making use of the binding. Checkpatch.pl
will also warn if you use a compatible that isn't documented, which
happens (shortly) if you first add the driver.

Jonas
