02bfc030e4 OMAP: omap_hwmod: call omap_hwmod init at boot; create interconnects
Connect the omap_hwmod code to the kernel boot.  Create some basic
interconnect and device structures for OMAP2/3 chips.

b3c6df3ab2 OMAP2/3 board-*.c files: read bootloader configuration earlier
Most board-*.c files read configuration data from the bootloader in
their .init_machine() function.  This needs to happen earlier, at some
point before omap2_init_common_hw() is called.  This is because a
future patch will use the bootloader serial console port information
to enable the UART clocks earlier, immediately after omap2_clk_init().
This is in turn necessary since otherwise clock tree usecounts on
clocks like dpll4_m2x2_ck will be bogus, which can cause the
currently-active console UART clock to be disabled during boot.

c0407a96d0 OMAP2/3 PM: create the OMAP PM interface and add a default OMAP PM no-op layer
The interface provides device drivers, CPUFreq, and DSPBridge with a
means of controlling OMAP power management parameters that are not yet
supported by the Linux PM PMQoS interface.  Copious documentation is
in the patch in Documentation/arm/OMAP/omap_pm and the interface
header file, arch/arm/plat-omap/include/mach/omap-pm.h.

Thanks to Rajendra Nayak <rnayak@ti.com> for adding CORE (VDD2) OPP
support and moving the OPP table initialization earlier in the event
that the clock code needs them.  Thanks to Tero Kristo
<tero.kristo@nokia.com> for fixing the parameter check in
omap_pm_set_min_bus_tput().  Jouni signed off on Tero's patch.

58cda884ec OMAP3 SDRC: add support for 2 SDRAM chip selects
Some OMAP3 boards (Beagle Cx, Overo, RX51, Pandora) have 2
SDRAM parts connected to the SDRC.

This patch adds the following:
- add a new argument of type omap_sdrc_params struct*
to omap2_init_common_hw and omap2_sdrc_init for the 2nd CS params
- adapted the OMAP boards files to the new prototype of
omap2_init_common_hw
- add the SDRC 2nd CS registers offsets defines
- adapt the sram sleep code to configure the SDRC for the 2nd CS

Note: If the 2nd param to omap2_init_common_hw is NULL, then the
parameters are not programmed into the SDRC CS1 registers

Tested on 3430 SDP and Beagleboard rev C2 and B5, with
suspend/resume and frequency changes (cpufreq).

2f135eaf18 OMAP3 clock: initialize SDRC timings at kernel start
On the OMAP3, initialize SDRC timings when the kernel boots.  This ensures
that the kernel is running with known, optimized SDRC timings, rather than
whatever was configured by the bootloader.

44169075e6 ARM: OMAP4: Add minimal support for omap4
This patch adds the support for OMAP4. The platform and machine specific
headers and sources updated for OMAP4430 SDP platform.

OMAP4430 is Texas Instrument's SOC based on ARM Cortex-A9 SMP architecture.
It's a dual core SOC with GIC used for interrupt handling and SCU for cache
coherency.

87246b7567 [ARM] OMAP2 SDRC: add SDRAM timing parameter infrastructure
For a given SDRAM clock rate, SDRAM chips require memory controllers
to use a specific set of timing minimums and maximums to transfer data
reliably.  These parameters can be different for different memory chips
and can also potentially vary by board.

This patch adds the infrastructure for board-*.c files to pass this
timing data to the SDRAM controller init function.  The timing data is
specified in an 'omap_sdrc_params' structure, in terms of SDRC
controller register values.  An array of these structs, one per SDRC
target clock rate, is passed by the board-*.c file to
omap2_init_common_hw().

This patch does not define the values for different memory chips, nor
does it use the values for anything; those will come in subsequent patches.

f2ab99778a [ARM] OMAP2 SDRC: separate common OMAP2/3 code from OMAP2xxx code
Separate SDRC code common to OMAP2/3 from mach-omap2/sdrc2xxx.c to
mach-omap2/sdrc.c.  Rename the OMAP2xxx-specific functions to use an
'omap2xxx' prefix rather than an 'omap2' prefix, and use "sdrc" in the
function names rather than "memory."  Mark several functions
as static that should not be used outside the sdrc2xxx.c file.

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.

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.
