Paul Walmsley dc0b3a7014 OMAP2+: clockdomains: move clockdomain static data to .c files
Static data should be declared in .c files, not .h files.  It should be
possible to #include .h files at any point without creating multiple
copies of the same data.

We converted the clock data to .c files some time ago.  This patch does
the same for the clockdomain data.

Rajendra Nayak 74bea6b988 OMAP: powerdomain: Move static allocations from powerdomains.h to a .c file
powerdomains.h header today has only static definitions.  Adding any
function declarations into it and including it in multiple source file
is expected to cause issues.  Hence move all the static definitions
from powerdomains.h file into powerdomains_data.c file.

Also, create a new powerdomain section of the mach-omap2/Makefile, and
rearrange the prcm-common part of the Makefile, now that the
powerdomain code is in its own Makefile section.

Paul Walmsley ff2516fbef OMAP2+: wd_timer: disable on boot via hwmod postsetup mechanism
The OMAP watchdog timer IP blocks require a specific set of register
writes to occur before they will be disabled[1], even if the device
clocks appear to be disabled in the CM_*CLKEN registers.  In the MPU
watchdog case, failure to execute this reset sequence will eventually
cause the watchdog to reset the OMAP unexpectedly.

Previously, the code to disable this watchdog was manually called from
mach-omap2/devices.c during device initialization.  This causes the
watchdog to be unconditionally disabled for a portion of kernel
initialization.  This should be controllable by the board-*.c files,
since some system integrators will want full watchdog coverage of
kernel initialization.  Also, the watchdog disable code was not
connected to the hwmod shutdown code.  This means that calling
omap_hwmod_shutdown() will not, in fact, disable the watchdog, and the
goal of omap_hwmod_shutdown() is to be able to shutdown any on-chip
OMAP device.

To resolve the latter problem, populate the pre_shutdown pointer in
the watchdog timer hwmod classes with a function that executes the
watchdog shutdown sequence.  This allows the hwmod code to fully
disable the watchdog.

Then, to allow some board files to support watchdog coverage
throughout kernel initialization, add common code to mach-omap2/io.c
to cause the MPU watchdog to be disabled on boot unless a board file
specifically requests it to remain enabled.  Board files can do this
by changing the watchdog timer hwmod's postsetup state between the
omap2_init_common_infrastructure() and omap2_init_common_devices()
function calls.

Paul Walmsley 2092e5ccf8 OMAP2+: hwmod: add postsetup state
Allow board files and OMAP core code to control the state that some or
all of the hwmods end up in at the end of _setup() (called by
omap_hwmod_late_init() ).  Reimplement the old skip_setup_idle code in
terms of this new postsetup state code.

There are two use-cases for this patch: the !CONFIG_PM_RUNTIME case,
in which all IP blocks should stay enabled after _setup() finishes;
and the MPU watchdog case, in which the watchdog IP block should enter
idle if watchdog coverage of kernel initialization is desired, and
should be disabled otherwise.

Paul Walmsley 4805734bcc OMAP2+: io: split omap2_init_common_hw()
Split omap2_init_common_hw() into two functions.  The first,
omap2_init_common_infrastructure(), initializes the hwmod code and
data, the OMAP PM code, and the clock code and data.  The second,
omap2_init_common_devices(), handles any other early device
initialization that, for whatever reason, has not been or cannot be
moved to initcalls or early platform devices.

This patch is required for the hwmod postsetup patch, which allows
board files to change the state that hwmods should be placed into at
the conclusion of the hwmod _setup() function.  For example, for a
board whose creators wish to ensure watchdog coverage across the
entire kernel boot process, code to change the watchdog's postsetup
state will be added in the board-*.c file between the
omap2_init_common_infrastructure() and omap2_init_common_devices() function
calls.

Paul Walmsley 97d60162f6 OMAP: hwmod: allow omap_hwmod_late_init() caller to skip module idle in _setup()
On kernels that don't use the omap_device_enable() calls to enable
devices, leave all on-chip devices enabled in hwmod _setup().
Otherwise, accesses to those devices are likely to fail, crashing the
system.  It's expected that kernels built without CONFIG_PM_RUNTIME
will be the primary use-case for this.  This functionality is
controlled by adding an extra parameter to omap_hwmod_late_init().

This patch is based on the patch "OMAP: hwmod: don't auto-disable
hwmod when !CONFIG_PM_RUNTIME" by Kevin Hilman

Note that with the pending serial.c patches you need to

Kevin Hilman aa4b1f6e83 OMAP4: fix temporary hacks that break multi-omap PM
When building for multi-omap, and OMAP4 is enabled, CONFIG_ARCH_OMAP4
will be true and prevent included code from building/running for
OMAP2/3 as well.

This problem exists in io.c where some hwmod/PM/SDRC init code is
prevented from running even on OMAP2/3 when OMAP4 is included in a
multi-OMAP build.

A quick glance suggests that this #ifndef is no longer needed in most
of the cases.  In the remaining cases, the function is wrapped with
"if (cpu_is_omap24xx() || cpu_is_omap34xx())" which will be optimized
out for OMAP4-only builds.

Note that this is only a short-term fix.  Longer-term, OMAP4
needs to create init functions for SDRC and hwmod late-init.

Paul Walmsley 81b34fbecb OMAP2 clock: split OMAP2420, OMAP2430 clock data into their own files
In preparation for multi-OMAP2 kernels, split
mach-omap2/clock2xxx_data.c into mach-omap2/clock2420_data.c and
mach-omap2/clock2430_data.c.  2430 uses a different device space
physical memory layout than past or future OMAPs, and we use a
different virtual memory layout as well, which causes trouble for
architecture-level code/data that tries to support both.  We tried
using offsets from the virtual base last year, but those patches never
made it upstream; so after some discussion with Tony about the best
all-around approach, we'll just grit our teeth and duplicate the
structures.  The maintenance advantages of a single kernel config that
can compile and boot on OMAP2, 3, and 4 platforms are simply too
compelling.

This approach does have some nice benefits beyond multi-OMAP 2 kernel
support.  The runtime size of OMAP2420-specific and OMAP2430-specific
kernels is smaller, since unused clocks for the other OMAP2 chip will
no longer be compiled in.  (At some point we will mark the clock data
__initdata and allocate it during registration, which will eliminate
the runtime memory advantage.)  It also makes the clock trees slightly
easier to read, since 2420-specific and 2430-specific clocks are no
longer mixed together.

This patch also splits 2430-specific clock code into its own file,
mach-omap2/clock2430.c, which is only compiled in for 2430 builds -
mostly for organizational clarity.

While here, fix a bug in the OMAP2430 clock tree: "emul_ck" was
incorrectly marked as being 2420-only, when actually it is present on
both OMAP2420 and OMAP2430.

Thanks to Tony for some good discussions about how to approach this
problem.

Paul Walmsley 657ebfadc1 OMAP3/4 clock: split into per-chip family files
clock34xx_data.c now contains data for the OMAP34xx family, the
OMAP36xx family, and the OMAP3517 family, so rename it to
clock3xxx_data.c.  Rename clock34xx.c to clock3xxx.c, and move the
chip family-specific clock functions to clock34xx.c, clock36xx.c, or
clock3517.c, as appropriate.  So now "clock3xxx.*" refers to the OMAP3
superset.

The main goal here is to prepare to compile chip family-specific clock
functions only for kernel builds that target that chip family.  To get to
that point, we also need to add CONFIG_SOC_* options for those other
chip families; that will be done in future patches, planned for 2.6.35.

OMAP4 is also affected by this.  It duplicated the OMAP3 non-CORE DPLL
clkops structure.  The OMAP4 variant of this clkops structure has been
removed, and since there was nothing else currently in clock44xx.c, it
too has been removed -- it can always be added back later when there
is some content for it.  (The OMAP4 clock autogeneration scripts have been
updated accordingly.)

Paul Walmsley 7adb998717 OMAP2xxx IO mapping: mark DSP mappings as being 2420-only
Out of the three major OMAP2 chip types, OMAP2420, OMAP2430, and OMAP3430,
we only map the IVA on OMAP2420.  The memory mapping is not shared between
OMAP2420 and OMAP2430, so it is inappropriate to label those macros as
'24XX'; this patch changes them to '2420'.

Tomi Valkeinen afedec183e OMAP: Add VRAM manager
Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used
to allocate large continuous blocks of SDRAM or SRAM. The features VRAM
manager has that are missing from dma_alloc_* functions are:

- Support for OMAP2's SRAM
- Allocate without ioremapping
- Allocate at defined physical addresses
- Allows larger VRAM area and larger allocations

The upcoming DSS2 uses VRAM manager.

VRAM area size can be defined in kernel config, board file or with
kernel boot parameters. Board file definition overrides kernel config,
and boot parameter overrides kernel config and board file.

Split arch/arm/plat-omap/include/mach/omapfb.h into two files:

include/linux/omapfb.h - ioctls etc for userspace and some kernel
                         stuff for board files
drivers/video/omap/omapfb.h - for omapfb internal use

This cleans up omapfb.h and also makes it easier for the upcoming new
DSS driver to co-exist with the old driver.

This patch enables omap_serial_early_init() function for OMAP4430
SDP. Without this the bootup would throw oops in omap_serial_init().

Note that the ifndef CONFIG_ARCH_OMAP4 is split into two sections
to enable omap_serial_early_init(). This ifndef cannot be removed
until omap4 clock framework is implemented.

Paul Walmsley 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.

Jean Pihet 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).
