Dependencies description:
All patches should go through the Samsung SoC tree.
The acpm-clk driver (#4) depends on the ACPM DVFS ops (#2).
If the clock subsystem needs to merge the new clock driver, it will
need an immutable tag with the 2 patches.
No dependecies for #1, #3, #5.

The Alive CLock and Power Manager (ACPM) firmware exposes clocks that
are variable and index based. These clocks don't provide an entire range
of values between the limits but only discrete points within the range.
The firmware also manages the voltage scaling appropriately with the
clock scaling. Make the ACPM node a clock provider.

Add support for the ACPM DVFS protocol. It translates clock frequency
requests to messages that can be interpreted by the ACPM firmware.
Add an ACPM clock driver to model the clocks exposed by the ACPM firmware.

Thanks,
