davinci: major rework of clock, PLL, PSC infrastructure
This is a significant rework of the low-level clock, PLL and Power Sleep Controller (PSC) implementation for the DaVinci family. The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

21config DAVINCI_RESET_CLOCKS
22 bool "Reset unused clocks during boot"
23 depends on ARCH_DAVINCI
24 help
25 Say Y if you want to reset unused clocks during boot.
26 This option saves power, but assumes all drivers are
27 using the clock framework. Broken drivers that do not
28 yet use clock framework may not work with this option.
29 If you are booting from another operating system, you
30 probably do not want this option enabled until your
31 device drivers work properly.
