Even when CONFIG_PM=n, we try to scale the boot voltage to a sane,
known value using OPP table to find matching voltage based on boot
frequency. This should be done, even when CONFIG_PM=n to avoid
mis-configured bootloaders and/or boot voltage assumptions made by
boot loaders.
Also fixes various compile problems due to depenencies between voltage
domain and powerdomain code (also present when CONFIG_PM=n).

As part of the voltage layer cleanup, split out VC specific code into
a dedicated VC layer. This patch primarily just moves VC code from
voltage.c into vc.c, and adds prototypes to vc.h.
No functional changes.
For readability, each function was given a local 'vc' pointer:
struct omap_vc_instance_data *vc = voltdm->vdd->vc_data;
and a global replace of s/vdd->vc_data/vc/ was done.
Also vc_init was renamed to vc_init_channel to reflect that this is
per-VC channel initializtion.

In commit 7538e3db6e (PM: add support

Rather than using the platform_bus dev_pm_ops overrides
(platform_bus_set_pm_ops()), this patch moves the OMAP runtime PM
implementation over to using device power domains.
Since OMAP is the only user of platform_bus_set_pm_ops(), that
interface can be removed (and will be in a forthcoming patch.)

This is a first pass at reorganizing mach-omap2/voltage.c:
- Separate almost all of the data from the code of mach-omap2/voltage.c.
The code remains in mach-omap2/voltage.c. The data goes into one
of several places, depending on what type of data it is:
- Silicon process/validation data: mach-omap2/opp*_data.c
- VC (Voltage Controller) data: mach-omap2/vc*_data.c
- VP (Voltage Processor) data: mach-omap2/vp*_data.c
- Voltage domain data: mach-omap2/voltagedomains*_data.c
The ultimate goal is for all this data to be autogenerated, the same
way we autogenerate the rest of our data.
- Separate VC and VP common data from VDD-specific VC and VP data.
- Separate common voltage.c code from SoC-specific code; reuse common code.
- Reorganize structures to avoid unnecessary memory loss due to unpacked
fields.
There is much left to be done. VC code and VP code should be separated out
into vc*.c and vp*.c files. Many fields in the existing structures are
superfluous, and should be removed. Some code in voltage.c seems to be
duplicated; that code should be moved into functions of its own. Proper
voltage domain code should be created, as was done with the powerdomain
and clockdomains, and powerdomains should reference voltagedomains.

The driver maintains the global voltage table on a per

efuse offset, errminlimit and voltage processor errorgain.
The driver also allows the voltage parameters dependent on the

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.

[khilman: fixed link error for OMAP2-only defconfig]
Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
In some ways, the OMAP4 PRCM register layout is quite different than
the OMAP2/3 PRCM register layout. For example, on OMAP2/3, from a
register layout point of view, all CM instances were located in the CM
subsystem, and all PRM instances were located in the PRM subsystem.
OMAP4 changes this. Now, for example, some CM instances, such as
WKUP_CM and EMU_CM, are located in the system PRM subsystem. And a
"local PRCM" exists for the MPU - this PRCM combines registers that
would normally appear in both CM and PRM instances, but uses its own
register layout which matches neither the OMAP2/3 PRCM layout nor the
OMAP4 PRCM layout.
To try to deal with this, introduce some new functions, omap4_cminst*
and omap4_prminst*. The former is to be used when writing to a CM
instance register (no matter what subsystem or hardware module it
exists in), and the latter, similarly, with PRM instance registers.
To determine which "PRCM partition" to write to, the functions take a
PRCM instance ID argument. Subsequent patches add these partition IDs
to the OMAP4 powerdomain and clockdomain definitions.
As far as I can see, there's really no good way to handle these types
of register access inconsistencies. This patch seemed like the least
bad approach.
Moving forward, the long-term goal is to remove all direct PRCM
register access from the PM code. PRCM register access should go
through layers such as the powerdomain and clockdomain code that can
hide the details of how to interact with the specific hardware
variant.
While here, rename cm4xxx.c to cm44xx.c to match the naming convention
of the other OMAP4 PRCM files.

In preparation for adding OMAP4-specific PRCM accessor/mutator
functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific

moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was
OMAP2xxx/3xxx-specific.
This process also requires the #includes in each of these files to be
changed to reference the new file name. As part of doing so, add some
comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use
"sideways includes", to indicate that these users of the PRM/CM includes
should not be doing so.
