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 SPL_CLK_CCF
	bool "SPL Common Clock Framework [CCF] support "
	depends on SPL
	help
	  Enable this option if you want to (re-)use the Linux kernel's Common
	  Clock Framework [CCF] code in U-Boot's SPL.

config SPL_CLK_COMPOSITE_CCF
	bool "SPL Common Clock Framework [CCF] composite clk support "
	depends on SPL_CLK_CCF
	help
	  Enable this option if you want to (re-)use the Linux kernel's Common
	  Clock Framework [CCF] composite code in U-Boot's SPL.

config CLK_CCF
	bool "Common Clock Framework [CCF] support "
	help
	  Enable this option if you want to (re-)use the Linux kernel's Common
	  Clock Framework [CCF] code in U-Boot's clock driver.

config CLK_COMPOSITE_CCF
	bool "Common Clock Framework [CCF] composite clk support "
	depends on CLK_CCF
	help
	  Enable this option if you want to (re-)use the Linux kernel's Common
	  Clock Framework [CCF] composite code in U-Boot's clock driver.

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_TI_SCI
	bool "TI System Control Interface (TI SCI) clock driver"
	depends on CLK && TI_SCI_PROTOCOL && OF_CONTROL
	help
	  This enables the clock driver support over TI System Control Interface
	  available on some new TI's SoCs. If you wish to use clock resources
	  managed by the TI System Controller, say Y here. Otherwise, say N.

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_VEXPRESS_OSC
	bool "Enable driver for Arm Versatile Express OSC clock generators"
	depends on CLK && VEXPRESS_CONFIG
	help
	  This clock driver adds support for clock generators present on
	  Arm Versatile Express platforms.

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

	depends on ARCH_STM32MP && CLK
	default y
	help
	  Enable the STM32 clock (RCC) driver. Enable support for
	  manipulating STM32MP1's on-SoC clocks.
