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 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 CLK_BOSTON 24 def_bool y if TARGET_BOSTON 25 depends on CLK 26 select REGMAP 27 select SYSCON 28 help 29 Enable this to support the clocks 30 31source "drivers/clk/tegra/Kconfig" 32source "drivers/clk/uniphier/Kconfig" 33source "drivers/clk/exynos/Kconfig" 34source "drivers/clk/at91/Kconfig" 35 36endmenu 37
