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.

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.

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

76config CLK_INTEL
77	bool "Enable clock driver for Intel x86"
78	depends on CLK && X86
79	help
80	  This provides very basic support for clocks on Intel SoCs. The driver
81	  is barely used at present but could be expanded as needs arise.
82	  Much clock configuration in U-Boot is either set up by the FSP, or
83	  set up by U-Boot itself but only statically. Thus the driver does not
84	  support changing clock rates, only querying them.
85
86config CLK_OCTEON
87	bool "Clock controller driver for Marvell MIPS Octeon"
88	depends on CLK && ARCH_OCTEON
89	default y
