Subject: [PATCH 079/182] 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.
