Tony Lindgren 65fa3e719f ARM: OMAP2+: Remove legacy i2c.c platform init code
We can now initialize I2C for mach-omap2 using device tree. And we
can move the remaining code in plat-omap/i2c.c into mach-omap1/i2c.c.

Note that we cannot remove some of the I2C bus reset functions
as they are being used by hwmod code.

Masahiro Yamada ac84eb47cc kbuild: remove unnecessary variable initializaions
Clearing obj-y, obj-m, obj-n, obj- in each Makefile is
a useless habit.

They are non-exported variables; therefore they are always empty
whenever descending into each subdirectory.
(Moreorver, obj-y and obj-m are also set to empty at the beginning
of scripts/Makefile.build)

Suman Anna c869c75c16 mailbox/omap: move the OMAP mailbox framework to drivers
The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.

The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).

As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
  and private header files. The public header has only the API related
  functions and types.
- The module name mailbox.ko from plat-omap is changed to
  omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
    mailbox_omap1.ko for OMAP1
    mailbox_omap2.ko for OMAP2+

Tony Lindgren a069486162 ARM: OMAP2+: Enable ARCH_MULTIPLATFORM support
Flip on multiplatform support for omap2+.

No changes to omap2plus_defconfig needed, but please note
that you may need to update your custom config files to
make sure you have:

CONFIG_ARCH_MULTIPLATFORM=y
CONFIG_ARCH_MULTI_V7=y
CONFIG_ARCH_OMAP2PLUS=y

And may need CONFIG_ARCH_MULTI_V6=y if booting omap2 boards.

Linus Torvalds 8d91a42e54 ARM: arm-soc: late cleanups for omap
From Tony Lindgren:
 Here are few more patches to finish the omap changes for
 multiplatform conversion that are not strictly fixes, but
 were too complex to do with the dependencies during the
 merge window. Those are to move of serial-omap.h to
 platform_data, and the removal of remaining cpu_is_omap
 macro usage outside mach-omap2.
 
 Then there are several trivial fixes for typos and few
 minimal omap2plus_defconfig updates.

Looks like we missed plat-omap/fb.c for cpu_is_omap usage
mach-omap2. This is the last user of cpu_is_omap, so let's
quickly fix it up so we can finally remove plat/cpu.h for
omap2lus.

We want to limit cpu_is_omap macro usage to mach-omap2 only so
we can make plat/cpu.h private. After this we can finally drop
plat/cpu.h for omap2+.

Split plat-omap/common.c into three pieces:

1. the 32KiHz sync timer and clocksource code, which now lives in

2. the OMAP2+ common code, which has been moved to mach-omap2/common.c;

3. and the remainder of the OMAP-wide common code, which includes the
   deprecated ATAGs code and a deprecated video RAM reservation function.

The primary motivation for doing this is to move the OMAP2+-specific parts
into an OMAP2+-specific file, so that build breakage related to the
System Control Module code can be resolved.

Paul Walmsley b04b65ab5b OMAP2/3/4 core: create omap_device layer
The omap_device code provides a mapping of omap_hwmod structures into
the platform_device system, and includes some details on external
(board-level) integration.  This allows drivers to enable, idle, and
shutdown on-chip device resources, including clocks, regulators, etc.
The resources enabled and idled are dependent on the device's maximum
wakeup latency constraint (if present).

At the moment, omap_device functions are intended to be called from
platform_data function pointers.  Ideally in the future these
functions will be called from either subarchitecture-specific
platform_data activate, deactivate functions, or via an custom
bus/device type for OMAP.

Kevin Hilman a57fb870c8 ARM: OMAP: Timer32K: Move timer32k to mach-omap1
Move now OMAP1-specific timer32k code to mach-omap1 since OMAP2/3 32k
timers are done in gptimer code.

Kevin Hilman 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.

Jarkko Nikula 85d05fb3fd ARM: OMAP: Add helper module for board specific I2C bus registration
This helper module simplifies I2C bus registration for different OMAP
platforms by doing registration in one place only and to allow board
specific bus configuration like clock rate and number of busses configured.

Helper should cover OMAP processors from first to third generation.

This patch just adds the feature and current implementation cleanup and
board file modifications will be done in following patches.

David Brownell f604931238 ARM: OMAP: abstract debug card setup (smc, leds)
Additional cleanup for debug boards on H2/P2/H3/H4:  move the init
code that's not board-specific into a new file where it can be easily
shared between all the different boards (avoiding code duplication,
and making it easier to support more devices).  Make H4 use that.

This should be easy to drop in to the OMAP1 boards using these debug
cards; the only difference seems to be that the p2 does an extra reset
of the smc using the fpga (probably all boards could do that, if it's
necessary) and doesn't use the gpio mux or request APIs.

David Brownell 994c84ea52 ARM: OMAP: h4 must have blinky leds!!
This adds generic support for the "debug board" LEDs used by most of
TI's OMAP reference boards, and board-specific support for the H4.

It's derived from the not-as-generic stuff used by OMAP1 H2/H3/P2.
Those should be able to switch easily to this version, and clean up
some of the omap1-specific code.

In addition to H4 support, one key improvement is supporting not just
the "old" ARM debug LED API (with timer and idle LEDs, plus four that
can be handy for kernel debugging), but it also supports the "new"
generic LED API (most useful for usermode stuff IMO).  Either or both
APIs can be enabled.
