The first two patches fix a clock framework bug and break a reset-controller
include ordering requirement.
The next 3 patches are generic clock framework patches. They add support for
regmap and for setting the rate and the parent at the same time based on
patches from James Hogan's remuxing set_rate series.
After that we add MSM clock hardware support and SoC specific drivers. The DT
node additions will be sent through the MSM maintainers once these patches are
accepted.
Some questions:
1) The clock controller is also a power domain controller.
Should we put that code in the drivers under drivers/clk/msm?
2) Should the directory be renamed to qcom to match the binding?
(I will probably do this for the next spin)
3) What is the right place for clock dt binding #defines? clk/ or clock/?
Changes since v2:
* Completed 8960 and 8974 GCC data & dt-bindings
* Added support for reset controllers
* Squashed some bugs in 8974 gcc clocks
* New patch to fix clk NULL pointer deref
* New patch to fix #include requirement for reset-controller.h
Changes since v1:
* Rewrote binding to use #clock-cells=1
* Reworked library components (pll, rcg, branch) to use regmap
* Dropped common clock framework patches that did DT parsing
* New patches for regmap support in common clock framework
