Subject: clk: qcom: Move cxo/pxo/xo into dt files
|
|
|
|
Put these clocks into the dt files instead of registering them
|
|
from C code. This provides a few benefits. It allows us to
|
|
specify the frequency of these clocks at the board level instead
|
|
of hard-coding them in the driver. It allows us to insert an RPM
|
|
clock in between the consumers of the crystals and the actual
|
|
clock. And finally, it helps us transition the GCC driver to use
|
|
RPM clocks when that configuration is enabled.
