3config CLK
4	bool "Enable clock driver support"
5	depends on DM
6	help
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.
12
13config SPL_CLK
14	bool "Enable clock support in SPL"
15	depends on CLK && SPL && SPL_DM
16	help
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.
22
23config TPL_CLK
24	bool "Enable clock support in TPL"
25	depends on CLK && TPL_DM
26	help
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.

33config CLK_BCM6345
34	bool "Clock controller driver for BCM6345"
35	depends on CLK && ARCH_BMIPS
36	default y
37	help
38	  This clock driver adds support for enabling and disabling peripheral
39	  clocks on BCM6345 SoCs. HW has no rate changing capabilities.

41config CLK_BOSTON
42	def_bool y if TARGET_BOSTON
43	depends on CLK
44	select REGMAP
45	select SYSCON
46	help
47	  Enable this to support the clocks
48
49config CLK_STM32F
50	bool "Enable clock driver support for STM32F family"
51	depends on CLK && (STM32F7 || STM32F4)
52	default y
53	help
54	  This clock driver adds support for RCC clock management
55	  for STM32F4 and STM32F7 SoCs.
56
57config CLK_HSDK
58	bool "Enable cgu clock driver for HSDK"
59	depends on CLK
60	help
61	  Enable this to support the cgu clocks on Synopsys ARC HSDK
62
63config CLK_ZYNQ
64	bool "Enable clock driver support for Zynq"
65	depends on CLK && ARCH_ZYNQ
66	default y
67	help
68	  This clock driver adds support for clock realted settings for
69	  Zynq platform.
70
71config CLK_ZYNQMP
72	bool "Enable clock driver support for ZynqMP"
73	depends on ARCH_ZYNQMP
74	help
75	  This clock driver adds support for clock realted settings for
76	  ZynqMP platform.
77
78config CLK_STM32MP1
79	bool "Enable RCC clock driver for STM32MP1"
80	depends on ARCH_STM32MP && CLK
81	default y
82	help
83	  Enable the STM32 clock (RCC) driver. Enable support for
84	  manipulating STM32MP1's on-SoC clocks.

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