Add support for CDCE913/925/937/949 family of devices. These are modular PLL-based low cost, high performance, programmable clock synthesizers, multipliers and dividers. They generate up to 9 output clocks from a single input frequency. The initial version of the driver does not support programming of the PLLs, and thus they run in the bypass mode only. The code is loosely based on the linux kernel cdce9xx driver. Signed-off-by: Tero Kristo <t-kristo@ti.com>

bool "Enable clock driver support"

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.

The clock subsystem adds a small amount of overhead to the image.

If this is acceptable and you have a need to use clock drivers in
|
|
SPL, enable this option. It might provide a cleaner interface to
|
|
setting up clocks within SPL, and allows the same drivers to be
|
|
used as U-Boot proper.
