cc26b3b01b ARM: OMAP3: Add minimal omap3430 support
Add minimal omap3430 support based on earlier patches from
Syed Mohammed Khasim. Also merge in omap34xx SRAM support
from Karthik Dasu and use consistent naming for sram init
functions.

Also do following changes that make 34xx support usable:

- Remove unused sram.c functions for 34xx

- Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally
  in entry-macro.S

- Update mach-omap2/io.c to support 2420, 2430, and 34xx

- Also merge in 34xx GPMC changes to add fields wr_access and
  wr_data_mux_bus from Adrian Hunter

- Remove memory initialization call omap2_init_memory() until
  until more generic memory initialization patches are posted.
  It's OK to rely on bootloader initialization until then.

1835f1d720 ARM: OMAP2: Move sleep.S into sleep24xx.S
Some register offsets are different for 242x and 243x. This
will allow compiling sleep code for both chips into the same
kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the
omap24xx_cpu_suspend instead of loading the values since the only.

Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL
instead of the address as that's what omap24xx_cpu_suspend expects to
determine between DDR and SDR. This bug has not been noticed as
the boards seem to have DDR instead of SDR.

Note that some PM patches are still missing. The PM patches will
be added later on once the base files are in sync with linux-omap
tree.

d459bfe01f ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain code
This patch creates an interface to the clockdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

The patch also adds clockdomain usecount tracking.  This is intended
to be called whenever the first clock in a clockdomain is enabled, or
when the last enabled clock in a clockdomain is disabled.  If the
clockdomain is in software-supervised mode, the code will force-wakeup
or force-sleep the clockdomain.  If the clockdomain is in
hardware-supervised mode, the first clock enable will add sleep and
wakeup dependencies on a user-selectable set of parent domains (usually
MPU & IVA2), and the disable will remove them.

Each clockdomain will be defined in later patches as static
structures.  The clockdomain structures are linked into a list at boot
by clkdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().

ad67ef6848 ARM: OMAP2: Powerdomain: Add base OMAP2/3 powerdomain code
This patch creates an interface to the powerdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

Each powerdomain will be defined in later patches as static
structures.  Also defined are dependencies between powerdomains,
used for adding and removing PM_WKDEP and CM_SLEEPDEP bits.  The
powerdomain structures are linked into a list at boot by
pwrdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_POWERDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().

6b8858a972 ARM: OMAP2: Change 24xx to use shared clock code and new reg access
This patch changes 24xx to use shared clock code and new register
access.

Note that patch adds some temporary OLD_CK defines to keep patch
more readable. These temporary defines will be removed in the next
patch. Also not all clocks are changed in this patch to limit the
size.

Also, the patch fixes few incorrect clock defines in clock24xx.h.

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.

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.
