The interface provides device drivers, CPUFreq, and DSPBridge with a means of controlling OMAP power management parameters that are not yet supported by the Linux PM PMQoS interface. Copious documentation is in the patch in Documentation/arm/OMAP/omap_pm and the interface header file, arch/arm/plat-omap/include/mach/omap-pm.h. Thanks to Rajendra Nayak <rnayak@ti.com> for adding CORE (VDD2) OPP support and moving the OPP table initialization earlier in the event that the clock code needs them. Thanks to Tero Kristo <tero.kristo@nokia.com> for fixing the parameter check in omap_pm_set_min_bus_tput(). Jouni signed off on Tero's patch.

Say Y if you want to reset unused clocks during boot.

This option saves power, but assumes all drivers are
|
|
using the clock framework. Broken drivers that do not
|
|
yet use clock framework may not work with this option.
|
|
If you are booting from another operating system, you
|
|
probably do not want this option enabled until your
|
|
device drivers work properly.
