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 "SPL Common Clock Framework [CCF] support "
53 Enable this option if you want to (re-)use the Linux kernel's Common
54 Clock Framework [CCF] code in U-Boot's SPL.
56 config SPL_CLK_COMPOSITE_CCF
57 bool "SPL Common Clock Framework [CCF] composite clk support "
58 depends on SPL_CLK_CCF
60 Enable this option if you want to (re-)use the Linux kernel's Common
61 Clock Framework [CCF] composite code in U-Boot's SPL.
64 bool "Common Clock Framework [CCF] support "
66 Enable this option if you want to (re-)use the Linux kernel's Common
67 Clock Framework [CCF] code in U-Boot's clock driver.
69 config CLK_COMPOSITE_CCF
70 bool "Common Clock Framework [CCF] composite clk support "
73 Enable this option if you want to (re-)use the Linux kernel's Common
74 Clock Framework [CCF] composite code in U-Boot's clock driver.
77 bool "Enable clock driver support for STM32F family"
78 depends on CLK && (STM32F7 || STM32F4)
81 This clock driver adds support for RCC clock management
82 for STM32F4 and STM32F7 SoCs.
85 bool "TI System Control Interface (TI SCI) clock driver"
86 depends on CLK && TI_SCI_PROTOCOL && OF_CONTROL
88 This enables the clock driver support over TI System Control Interface
89 available on some new TI's SoCs. If you wish to use clock resources
90 managed by the TI System Controller, say Y here. Otherwise, say N.
93 bool "Enable cgu clock driver for HSDK"
96 Enable this to support the cgu clocks on Synopsys ARC HSDK
99 bool "Enable clock driver support for Versal"
100 depends on ARCH_VERSAL
101 select ZYNQMP_FIRMWARE
103 This clock driver adds support for clock realted settings for
106 config CLK_VEXPRESS_OSC
107 bool "Enable driver for Arm Versatile Express OSC clock generators"
108 depends on CLK && VEXPRESS_CONFIG
110 This clock driver adds support for clock generators present on
111 Arm Versatile Express platforms.
114 bool "Enable clock driver support for Zynq"
115 depends on CLK && ARCH_ZYNQ
118 This clock driver adds support for clock realted settings for
122 bool "Enable clock driver support for ZynqMP"
123 depends on ARCH_ZYNQMP
124 select ZYNQMP_FIRMWARE
126 This clock driver adds support for clock realted settings for
130 bool "Enable RCC clock driver for STM32MP1"
131 depends on ARCH_STM32MP && CLK
134 Enable the STM32 clock (RCC) driver. Enable support for
135 manipulating STM32MP1's on-SoC clocks.
