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 && SPL && SPL_DM
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.
config TPL_CLK
bool "Enable clock support in TPL"
depends on CLK && TPL_DM
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 TPL, and allows the same drivers to be
used as U-Boot proper.
config CLK_BCM6345
bool "Clock controller driver for BCM6345"
depends on CLK && ARCH_BMIPS
default y
help
This clock driver adds support for enabling and disabling peripheral
clocks on BCM6345 SoCs. HW has no rate changing capabilities.
config CLK_BOSTON
def_bool y if TARGET_BOSTON
depends on CLK
select REGMAP
select SYSCON
help
Enable this to support the clocks
config CLK_STM32F
bool "Enable clock driver support for STM32F family"
depends on CLK && (STM32F7 || STM32F4)
default y
help
This clock driver adds support for RCC clock management
for STM32F4 and STM32F7 SoCs.
config CLK_HSDK
bool "Enable cgu clock driver for HSDK"
depends on CLK
help
Enable this to support the cgu clocks on Synopsys ARC HSDK
config CLK_ZYNQ
bool "Enable clock driver support for Zynq"
depends on CLK && ARCH_ZYNQ
default y
help
This clock driver adds support for clock realted settings for
Zynq platform.
config CLK_ZYNQMP
bool "Enable clock driver support for ZynqMP"
depends on ARCH_ZYNQMP
help
This clock driver adds support for clock realted settings for
ZynqMP platform.
config CLK_STM32MP1
bool "Enable RCC clock driver for STM32MP1"
depends on ARCH_STM32MP && CLK
default y
help
Enable the STM32 clock (RCC) driver. Enable support for
manipulating STM32MP1's on-SoC clocks.

Support for the ICS8N3QV01 Quad-Frequency VCXO (Voltage-Controlled
Crystal Oscillator). The output frequency can be programmed via an
I2C interface.
