Pull clk updates from Stephen Boyd:
"This time it looks like a quieter release cycle in the clk tree. I
guess that's because of summer time holidays/vacations. The biggest
change in the diffstat is in the Qualcomm clk driver, where they got
support for CPUs and handful of SoCs. After that, the at91 driver got
a major rewrite for newer DT bindings that should make things easier
going forward and the TI code moved to a clockdomain based design.
The long tail is mostly small driver updates for newer clks and some
simpler SoC clock drivers such as the Hisilicon and imx support.
In the core framework, we only have two small changes this time.
One is a new clk API to get all clks for a device with the bulk clk
APIs. This allows drivers that don't care about doing anything besides
turning on all the clks to just clk_get() them all and turn them on.
The other change is the beginning of a way to support save and restore
of clk settings in the clk framework. TI is the only user right now,
but we will want to expand upon this design in the future to support
more save and restore of clk registers. At least this gets us started
and works well enough for one SoC, but there's more work in the
future.
