The patch is the output from a python script which converts

The OMAP watchdog timer driver needs to determine what caused the SoC
to reset for its GETBOOTSTATUS ioctl.  So, define a set of standard
reset sources across OMAP SoCs.  For OMAP2xxx, 3xxx, and 4xxx SoCs,
define mappings from the SoC-specific reset source register bits to
the standardized reset source IDs.  Create SoC-specific PRM functions
that read the appropriate per-SoC register and use the mapping to
return the standardized reset bits.  Register the SoC-specific PRM
functions with the common PRM code via prm_register().  Create a
function in the common PRM code, prm_read_reset_sources(), that
calls the SoC-specific function, registered during boot.

This patch does not yet handle some SoCs, such as AM33xx.  Those SoCs
were not handled by the code this will replace.

Move OMAP3xxx-specific PRM functions & macros into prm3xxx.[ch] and
OMAP2xxx-specific macros into prm2xxx.h.  (prm2xxx.c will be created
by a subsequent patch when it's needed.)  Move basic PRM register
access functions into static inline functions in prm2xxx_3xxx.h, leaving
only OMAP2/3 hardreset functions in prm2xxx_3xxx.c.

Also clarify the initcall function naming to reinforce that this code
is specifically for the PRM IP block.

This is in preparation for the upcoming powerdomain series and the
upcoming move of this code to drivers/.

In preparation for adding OMAP4-specific PRCM accessor/mutator
functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific
files.  Most of what was in mach-omap2/{cm,prm}.{c,h} has now been
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.

Fix all of the remaining OMAP3 PRCM register shift/bitmask macros that
did not use the _SHIFT/_MASK suffixes to use them.  This makes the use
of these macros consistent.  It is intended to reduce error, as code
can be inspected visually by reviewers to ensure that bitshifts and
bitmasks are used in the appropriate places.

OMAP 3430 ES3.1 chips have a separate bit for IO daisy-chain
wake up enabling. It needs to be enabled when entering
retention or off state, otherwise waking up might not work
in all situations.

The OMAP3430ES2_SAVEANDRESTORE_SHIFT macro is used
by powerdomain code in
"1 << OMAP3430ES2_SAVEANDRESTORE_SHIFT" manner, but
the definition was also (1 << 4), meaning we actually
modified bit 16. So the definition needs to be 4.

This fixes also a cold reset HW bug in OMAP3430 ES3.x
where some of the efuse bits are not isolated during
wake-up from off mode. This can cause randomish
cold resets with off mode. Enabling the USBTLL hardware
SAVEANDRESTORE causes the core power up assert to be
delayed in a way that we will not get faulty values
when boot ROM is reading the unisolated registers.
