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.
