1menu "Clock" 2 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. 32 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. 40 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_TI_SCI 58 bool "TI System Control Interface (TI SCI) clock driver" 59 depends on CLK && TI_SCI_PROTOCOL && OF_CONTROL 60 help 61 This enables the clock driver support over TI System Control Interface 62 available on some new TI's SoCs. If you wish to use clock resources 63 managed by the TI System Controller, say Y here. Otherwise, say N. 64 65config CLK_HSDK 66 bool "Enable cgu clock driver for HSDK" 67 depends on CLK 68 help 69 Enable this to support the cgu clocks on Synopsys ARC HSDK 70 71config CLK_VEXPRESS_OSC 72 bool "Enable driver for Arm Versatile Express OSC clock generators" 73 depends on CLK && VEXPRESS_CONFIG 74 help 75 This clock driver adds support for clock generators present on 76 Arm Versatile Express platforms. 77 78config CLK_ZYNQ 79 bool "Enable clock driver support for Zynq" 80 depends on CLK && ARCH_ZYNQ 81 default y 82 help 83 This clock driver adds support for clock realted settings for 84 Zynq platform. 85 86config CLK_ZYNQMP 87 bool "Enable clock driver support for ZynqMP" 88 depends on ARCH_ZYNQMP 89 help 90 This clock driver adds support for clock realted settings for 91 ZynqMP platform. 92 93config CLK_STM32MP1 94 bool "Enable RCC clock driver for STM32MP1" 95 depends on ARCH_STM32MP && CLK 96 default y 97 help 98 Enable the STM32 clock (RCC) driver.
