4 bool "Enable clock driver support"
7 This allows drivers to be provided for clock generators, including
8 oscillators and PLLs. Devices can use a common clock API to request
9 a particular clock rate and check on available clocks. Clocks can
10 feed into other clocks in a tree structure, with multiplexers to
11 choose the source for each clock.
14 bool "Enable clock support in SPL"
15 depends on CLK && SPL && SPL_DM
17 The clock subsystem adds a small amount of overhead to the image.
18 If this is acceptable and you have a need to use clock drivers in
19 SPL, enable this option. It might provide a cleaner interface to
20 setting up clocks within SPL, and allows the same drivers to be
21 used as U-Boot proper.
24 bool "Enable clock support in TPL"
25 depends on CLK && TPL_DM
27 The clock subsystem adds a small amount of overhead to the image.
28 If this is acceptable and you have a need to use clock drivers in
29 SPL, enable this option. It might provide a cleaner interface to
30 setting up clocks within TPL, and allows the same drivers to be
31 used as U-Boot proper.
34 bool "Clock controller driver for BCM6345"
35 depends on CLK && ARCH_BMIPS
38 This clock driver adds support for enabling and disabling peripheral
39 clocks on BCM6345 SoCs. HW has no rate changing capabilities.
42 def_bool y if TARGET_BOSTON
47 Enable this to support the clocks
50 bool "Enable clock driver support for STM32F family"
51 depends on CLK && (STM32F7 || STM32F4)
54 This clock driver adds support for RCC clock management
55 for STM32F4 and STM32F7 SoCs.
58 bool "Enable cgu clock driver for HSDK"
61 Enable this to support the cgu clocks on Synopsys ARC HSDK
64 bool "Enable clock driver support for Zynq"
65 depends on CLK && ARCH_ZYNQ
68 This clock driver adds support for clock realted settings for
72 bool "Enable clock driver support for ZynqMP"
73 depends on ARCH_ZYNQMP
75 This clock driver adds support for clock realted settings for
79 bool "Enable RCC clock driver for STM32MP1"
80 depends on ARCH_STM32MP && CLK
83 Enable the STM32 clock (RCC) driver. Enable support for
84 manipulating STM32MP1's on-SoC clocks.
