ARM: OMAP2+: raw read and write endian fix
All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

ARM: OMAP: Move DT wake-up event handling over to use pinctrl-single-omap
Now pinctrl-single-omap can handle the wake-up events for us now
as long as the events are configured in the .dts files.

ARM: OMAP2+: PRM: initialize some PRM functions early
Some PRM functions will need to be called by the hwmod code early in
kernel init. To handle this, split the PRM initialization code into
early and late phases. The early init is handled via mach-omap2/io.c,
while the late init is handled by subsys_initcall().

ARM: OMAP2/3: PRM: add SoC reset functions (using the CORE DPLL method)
Add SoC reset functions into the PRM code. These functions are based
on code from mach-omap2/prcm.c. They reset the SoC using the CORE DPLL
reset method (as opposed to one of the other two or three chip reset
methods).
Adding them here will facilitate their removal from
arch/arm/mach-omap2/prcm.c. (prcm.c is deprecated.)

ARM: OMAP2+: PRM: create PRM reset source API for the watchdog timer driver
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.

ARM: OMAP2+: PRM: split PRM functions into OMAP2, OMAP3-specific files
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/.
