Clock drivers don't belong here, move them to the right place and declutter mach-snapdragon a bit. To de-couple these drivers from specific "target" platforms, add additional config options to enable each clock driver gated behind a common CLK_QCOM option and enable them by default for the respective targets. This will make future work easier as we move towards a generic Qualcomm target. Reviewed-by: Sumit Garg <sumit.garg@linaro.org> Signed-off-by: Caleb Connolly <caleb.connolly@linaro.org>

help
|
|
This allows drivers to be provided for clock generators, including
|
|
oscillators and PLLs. Devices can use a common clock API to request
|
|
a particular clock rate and check on available clocks. Clocks can
|
|
feed into other clocks in a tree structure, with multiplexers to
|
|
choose the source for each clock.

help

This provides very basic support for clocks on Intel SoCs. The driver
|
|
is barely used at present but could be expanded as needs arise.
|
|
Much clock configuration in U-Boot is either set up by the FSP, or
|
|
set up by U-Boot itself but only statically. Thus the driver does not
|
|
support changing clock rates, only querying them.
