Marek Vasut 36c2ee4ce5 clk: rmobile: Add RCar Gen3 clock driver
Add clock driver for the RCar Gen3 R8A7795 and R8A7796 SoCs .
This driver allows reading out the clock configuration set by
previous boot stages and enabling and disabling clock using
the MSTP registers. Setting clock is not supported thus far.

config CLK
bool "Enable clock driver support"
depends on DM
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.
config SPL_CLK
bool "Enable clock support in SPL"
depends on CLK
help
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.

help
This clock driver adds support for enabling and disabling peripheral
clocks on BCM6345 SoCs. HW has no rate changing capabilities.

help
This clock driver adds support for clock realted settings for
Zynq platform.

This clock driver adds support for clock realted settings for
ZynqMP platform.
