OMAP4 has three scalable voltage domains vdd_mpu, vdd_iva
and vdd_core. This patch adds the voltage tables and other
configurable voltage processor and voltage controller
settings to control these three scalable domains in OMAP4.

This patch adds voltage driver support for OMAP3. The driver
allows configuring the voltage controller and voltage
processors during init and exports APIs to enable/disable
voltage processors, scale voltage and reset voltage.
The driver maintains the global voltage table on a per
VDD basis which contains the various voltages supported by the
VDD along with per voltage dependent data like smartreflex
efuse offset, errminlimit and voltage processor errorgain.
The driver also allows the voltage parameters dependent on the
PMIC to be passed from the PMIC file through an API.
The driver allows scaling of VDD voltages either through
"vc bypass method" or through "vp forceupdate method" the
choice being configurable through the board file.
This patch contains code originally in linux omap pm branch
smartreflex driver. Major contributors to this driver are
Lesly A M, Rajendra Nayak, Kalle Jokiniemi, Paul Walmsley,
Nishant Menon, Kevin Hilman. The separation of PMIC parameters
into a separate structure which can be populated from
the PMIC file is based on the work of Lun Chang from Motorola
in an internal tree.

Move the padconf save code from pm34xx.c to the System Control Module
code in mach-omap2/control.c. This is part of the general push to
move direct register access from middle-layer core code to low-level
core code, so the middle-layer code can be abstracted to work on
multiple platforms and cleaned up.
In the medium-to-long term, this code should be called by the mux
layer code, not the PM idle code. This is because, according to the
TRM, saving the padconf only needs to be done when the padconf
changes[1].

Get rid of the open-coded scratchpad write in mach-omap2/prcm.c and
replace it with an actual API, omap3_ctrl_write_boot_mode(). While
there, get rid of the gratuitous omap_writel().
There's not much documentation available for what should wind up in
the scratchpad here, so more documentation would be appreciated.
Also, at some point, we should formalize our treatment of the scratchpad;
right now, accesses to the scratchpad are not well-documented.

Erratum id: i608
RTA (Retention Till Access) feature is not supported and leads to device
stability issues when enabled. This impacts modules with embedded memories
on OMAP3630
Workaround is to disable RTA on boot and coming out of core off.
For disabling RTA coming out of off mode, we do this by overriding the
restore pointer for 3630 as the first point of entry before caches are
touched and is common for GP and HS devices. To disable earlier than
this could be possible by modifying the PPA for HS devices, but not for
GP devices.

Only OMAP2+ platforms have the System Control Module (SCM) IP block.
In the past, we've kept the SCM header file in plat-omap. This has
led to abuse - device drivers including it; includes being added that
create implicit dependencies on OMAP2+ builds; etc.
In response, move the SCM headers into mach-omap2/.
As part of this, remove the direct SCM access from the OMAP UDC
driver. It was clearly broken. The UDC code needs an indepth review for
use on OMAP2+ chips.
