Stephen Boyd b3ee3eff57 clk: qcom: Add simple regmap based muxes
Add support for muxes that use regmap instead of readl/writel
directly. We don't support as many features as clk-mux.c, but
this is good enough to support getting and setting parents.
Adding a table based lookup can be added in the future if needed.

Kumar Gala 24d8fba44a clk: qcom: Add support for IPQ8064's global clock controller (GCC)
Add a driver for the global clock controller found on IPQ8064 based
platforms. This should allow most non-multimedia device drivers to probe
and control their clocks.

This is currently missing clocks for USB HSIC and networking devices.

Stephen Boyd 49fc825f0c clk: qcom: Consolidate common probe code
Most of the probe code is the same between all the different
clock controllers. Consolidate the code into a common.c file.
This makes changes to the common probe parts easier and reduces
chances for bugs.

According to Documentation/kbuild/makefiles.txt these symbols
should be clk-qcom-y. Otherwise the build will fail if
CONFIG_COMMON_CLK_QCOM=m. Fix it.

Stephen Boyd b36ba30c8a clk: qcom: Add reset controller support
Reset controllers and clock controllers are combined into one IP
block on Qualcomm chipsets. Usually a reset signal is associated
with each clock branch but sometimes a reset signal is associated
with a handful of clocks. Either way the register interface is
the same; set a bit to assert a reset and clear a bit to deassert
a reset. Add support for these types of resets signals.

RCGs are highly customizable mux/divider/counter clocks that can

source that is faster than the desired rate.
