69d88a00a2 ARM: OMAP2: Add common register access for 24xx and 34xx
This patch adds common register access for 24xx and 34xx power
and clock management in order to share code between 24xx and 34xx.

Only change USB platform init code to use new register access, other
access will be changed in later patches.

5a3a388fbe ARM: OMAP: Timer32K: Re-organize duplicated 32k-timer code
On OMAP2/3, the gp-timer code can be used for a 32kHz timer simply by
setting the source to be the 32k clock instead of sys_clk.

This patch uses the mach-omap2/timer-gp.c code for 32kHz timer on
OMAP2, moving the logic into mach-omap2/timer-gp.c, and not using
plat-omap/timer32k.c which, for OMAP2, is redundant with the timer-gp
code.

Also, if CONFIG_OMAP_32K_TIMER is enabled, the gptimer-based
clocksource is not used.  Instead the default 32k sync counter is used
as the clocksource (see the clocksource in plat-omap/common.c.)  This
is important for sleep/suspend so there is a valid counter during
sleep.  Note that the suspend/sleep code needs fixing to check for
overflows of this counter.

In addition, the OMAP2/3 details are removed from timer32k.c leaving
that with only OMAP1 specifics.  A follow-up patch will move it from
plat-omap common code to mach-omap1.

22a16f39e3 ARM: OMAP: Add initial 24xx suspend support
This patch adds support for omap24xx power domains and
allows suspend to work.

Please note that for some reason core power domain still
does not seem to idle.

Implement basic support for General-Purpose Memory Controller
as found on OMAP2420.

Dynamic CS address space allocation still needs to be done.

1dbae815a7 [ARM] 3145/1: OMAP 3a/5: Add support for omap24xx
Patch from Tony Lindgren

This patch adds support for omap24xx series of processors.
The files live in arch/arm/mach-omap2, and share common
files with omap15xx and omap16xx processors in
arch/arm/plat-omap.

Omap24xx support was originally added for 2.6.9 by TI.
This code was then improved and integrated to share common
code with omap15xx and omap16xx processors by various
omap developers, such as Paul Mundt, Juha Yrjola, Imre Deak,
Tony Lindgren, Richard Woodruff, Nishant Menon, Komal Shah
et al.
