3f96a2d90e Here is some more omap clean-up. The biggest changes are
hwmod, clock, and System Control Module cleanup, and the removal
 of the last instance of omap_read/write usage for omap2+ with
 the removal of unused USB OHCI Full Speed driver support. The
 removed OHCI is only currently used for omap1 as the actively
 used omap2+ boards have either MUSB or another instance of
 OHCI+EHCI that's more usable.

90f1380ef6 ARM: OMAP2+: control: new APIs to configure boot address and mode
SCM contains boot addr and boot mode registers to control
other processors on different OMAP versions. It controls the
boot address and mode for DSP based subsystems like: IVA 2.1
(OMAP2430), IVA 2.2 (OMAP3) and DSP (OMAP4).

If contained within SCM registers, when a processor is
booting it uses BOOTADDR to start running the code at that
location. BOOTMOD register specifies a different set of
modes for the processor to execute when booting (from direct,
idle, self-loop, user and default).

Since there was no offset associated with OMAP4, this patch
defines it.

This patch updates existing macros, functions used for TI816X, to enable
addition of other SoCs belonging to TI81XX family (e.g., TI814X).

The approach taken is to use TI81XX/ti81xx for code/data going to be common
across all TI81XX devices.

cpu_is_ti81xx() is introduced to handle code common across TI81XX devices.

In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved
in mach-omap2/common.c as same will be used for TI814X and is not board
specific.

14c79bbed7 ARM: pm: omap34xx: remove get_*_restore_pointer functions, directly use entry points
Upon return from off-mode, the ROM code jumps to a restore function
saved in the scratchpad.  Based on SoC revision or errata, this
restore entry point is different.  Current code uses some helper
functions in sleep34xx.S (get_*_restore_pointer) to get the restore
function entry point.

When returning from off-mode, this code is executed from SDRAM, so
there's no reason to use these helper functions when using the SDRAM
entry points directly would work just fine.

This patch uses ENTRY/ENDPROC to create "real" entry points for these
functions, and uses those values directly when writing the scratchpad.

Tested all three entry points
- restore_es3: 3430/n900
- restore_3630: 3630/Zoom3
- restore: 3530/Overo

2f34ce81b8 OMAP3: PM: Adding voltage driver support.
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.

596efe4792 OMAP3: control/PM: move padconf save code to mach-omap2/control.c
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].

458e999eb1 OMAP3630: PM: Erratum i608: disable RTA
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.

4814ced511 OMAP: control: move plat-omap/control.h to mach-omap2/control.h
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.
