    Subject[PATCH 00/10] PM: Create the AVS class of drivers
    Date
    From: Jean Pihet <j-pihet@ti.com>

    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/
