The current code base is not linking with the OMAP_PM_NONE
option set.
Since the option OMAP_PM_NOOP provides a no-op/debug layer,
OMAP_PM_NONE can be removed.
OMAP_PM_NOOP is enabled by default by Kconfig.

It appears that arch/arm/mach-omap2/timer-gp.o is needed by OMAP2PLUS.
Since timer-gp.o has direct dependencies on omap_dm_timer_*, it seems
correct for the architecture to depend upon OMAP_DM_TIMER, otherwise
unsuspecting integrators will be faced with a whole bunch of linker
errors at the end of their kernel build:

This patch extends the smartreflex framework to support
OMAP4. The changes are minor like compiling smartreflex Kconfig
option for OMAP4 also, and a couple of OMAP4 checks in
the smartreflex framework.

The change in sr_device.c where new logic has to be introduced
for reading the efuse registers is due to the fact that in OMAP4
the efuse registers are 24 bit aligned. A __raw_readl will
fail for non-32 bit aligned address and hence the 8-bit read
and shift.

Smartreflex Class3 implementation continuously monitors
silicon performance  and instructs the Voltage Processors
to increase or decrease the voltage.
This patch adds smartreflex class 3 driver. This driver hooks
up with the generic smartreflex driver smartreflex.c to abstract
out class specific implementations out of the generic driver.

Class3 driver is chosen as the default class driver for smartreflex.
If any other class driver needs to be implemented, the init of that
driver should be called from the board file. That way the new class driver
will over-ride the Class3 driver.

SmartReflex modules do adaptive voltage control for real-time
voltage adjustments. With Smartreflex the power supply voltage
can be adapted to the silicon performance(manufacturing process,
temperature induced performance, age induced performance etc).

There are differnet classes of smartreflex implementation.
	Class-0: Manufacturing Test Calibration
	Class-1: Boot-Time Software Calibration
	Class-2: Continuous Software Calibration
	Class-3: Continuous Hardware Calibration
	Class-4: Fully Integrated Power Management

OMAP3 has two smartreflex modules one associated with VDD MPU and the
other associated with VDD CORE.
This patch adds support for  smartreflex driver. The driver is designed
for Class-1 , Class-2 and Class-3 support and is  a platform driver.
Smartreflex driver can be enabled through a Kconfig option
"SmartReflex support" under "System type"->"TI OMAP implementations" menu.

Smartreflex autocompensation feature can be enabled runtime through
a debug fs option.
To enable smartreflex autocompensation feature
	echo 1 > /debug/voltage/vdd_<X>/smartreflex/autocomp
To disable smartreflex autocompensation feature
	echo 0 > /debug/voltage/vdd_<X>/smartreflex/autocomp

where X can be mpu, core , iva etc.

This patch contains code originally in linux omap pm branch.
Major contributors to this driver are
Lesly A M, Rajendra Nayak, Kalle Jokiniemi, Paul Walmsley,
Nishant Menon, Kevin Hilman.

This patch adds a save and restore mechanism for ARM L2 auxiliary control
register. The feature is enabled by default for GP devices, but for HS/EMU
devices the user must enable the service and define the PPA service ID to
be used for setting L2 aux ctrl, as this is not currently supported by the
bootloader. If nobody alters the contents of L2 aux ctrl from its reset
value, this feature is not needed.

Kconfig option to enable HS/EMU L2 aux save and restore:
- OMAP3_L2_AUX_SECURE_SAVE_RESTORE
Kconfig option to select HS/EMU PPA service for setting L2 aux ctrl:
- OMAP3_L2_AUX_SECURE_SERVICE_SET_ID

in the source files with "#define DEBUG", conforming to the practice for

unnecessary writes to omap uarts is avoided.

This patch is to sync the core linux-omap PM code with mainline.  This
code has evolved and been used for a while the linux-omap tree, but
the attempt here is to finally get this into mainline.

Following this will be a series of patches from the 'PM branch' of the
linux-omap tree to add full PM hardware support from the linux-omap
tree.

Much of this PM core code was written by Jouni Hogander with

from Nokia, Texas Instruments and linux-omap community.
