051c8d0b66 clk: qcom: Fix modular build
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.

0eeff27b49 clk: qcom: Add support for MSM8660's global clock controller (GCC)
Add a driver for the global clock controller found on MSM8660
based platforms. This should allow most non-multimedia device
drivers to probe and control their clocks.

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.

bcd61c0f53 clk: qcom: Add support for root clock generators (RCGs)
Add support for the root clock generators on Qualcomm devices.
RCGs are highly customizable mux/divider/counter clocks that can
be used to generate almost any rate desired given some input
source that is faster than the desired rate.

9e2631313c clk: qcom: Add support for phase locked loops (PLLs)
Add support for Qualcomm's PLLs (phase locked loops). This is
sufficient enough to be able to determine the rate the PLL is
running at. We can add rate setting support later when it's
needed.

085d7a4554 clk: qcom: Add a regmap type clock struct
Add a clock type that associates a regmap pointer and some
enable/disable bits with a clk_hw struct. This will be the struct
that a hw specific implementation wraps if it wants to use the
regmap helper functions.
