Georgi Djakov 3966fab8b6 clk: qcom: Add MSM8916 Global Clock Controller support
This patch adds support for the global clock controller found on the MSM8916
based devices. It allows the various device drivers to probe and control
their clocks and resets.

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.

Kumar Gala 2d85a713dc clk: qcom: Add basic support for APQ8064 global clock controller clocks
The APQ8064 and MSM8960 share a significant amount of clock data and
code between the two SoCs.  Rather than duplicating the data we just add
support for a unqiue APQ8064 clock table into the MSM8960 code.

For now add just enough clocks to get a basic serial port going on an
APQ8064 device.

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.
