- 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

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

- 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

- depends on CLK && ARCH_ZYNQ
- default y
- help
- This clock driver adds support for clock realted settings for
- Zynq platform.
