AVS is a power management technique which controls the operating
voltage of a device in order to optimize (i.e. reduce) its power
consumption. The voltage is adapted depending on static factors
(chip manufacturing process) and dynamic factors (temperature
depending performance).
AVS is also called SmartReflex on OMAP devices.
To that end, create the AVS framework in drivers/power/avs and
move the OMAP SmartReflex code to the new directory.
In preparation to the move of the OMAP code the following changes have been
made:
- split the include files into generic and platform specific code,
- fill in platform data from the device initialization code and pass
it to the driver,
- create CONFIG_AVS* config options accordingly.
The platform integration data for SmartReflex is passed from hwmod
and the voltage layer to the driver using pdata.
Tested on OMAP3 Beagleboard using omap2plus_defconfig with the
CONFIG_POWER_AVS* options set.
Based on master branch of the l-o git tree (3.3.0-rc6) [1], commit
85244e0edd240da2004bb2ab7cbcbc67a336f20d.

Jean Pihet (10):
ARM: OMAP3+: voltage: export functions to plat/voltage.h
ARM: OMAP2+: SmartReflex: move the platform specific macros in
plat-omap
ARM: OMAP3+: SmartReflex: class drivers should use struct omap_sr *
ARM: OMAP2+: smartreflex: Use the names from hwmod data instead of
voltage domains.
ARM: OMAP3: hwmod: rename the smartreflex entries
ARM: OMAP2+: SmartReflex: use the platform header file for voltage
functions
ARM: OMAP2+: SmartReflex: introduce a busy loop condition test macro
ARM: OMAP2+: SmartReflex: Use per-OPP data structure
ARM: OMAP2+: SmartReflex: add POWER_AVS Kconfig options
ARM: OMAP: SmartReflex: Move smartreflex driver to drivers/
