8c3d4534a8 ARM: OMAP2+: declare file-local functions as static
Several function declarations used only in the files in which they're
declared should include the static keyword, but don't:

    arch/arm/mach-omap2/serial.c:248:6: warning: symbol 'cmdline_find_option' was not declared. Should it be static?
    arch/arm/mach-omap2/omap-wakeupgen.c:259:6: warning: symbol 'irq_sar_clear' was not declared. Should it be static?
    arch/arm/mach-omap2/board-rx51-peripherals.c:878:27: warning: symbol 'rx51_vibra_data' was not declared. Should it be static?
    arch/arm/mach-omap2/board-rx51-peripherals.c:882:27: warning: symbol 'rx51_audio_data' was not declared. Should it be static?
    arch/arm/mach-omap2/board-omap4panda.c:201:29: warning: symbol 'omap_panda_wlan_data' was not declared. Should it be static?
    arch/arm/mach-omap2/board-omap4panda.c:393:24: warning: symbol 'omap4_panda_dvi_device' was not declared. Should it be static?
    arch/arm/mach-omap2/board-omap4panda.c:403:12: warning: symbol 'omap4_panda_dvi_init' was not declared. Should it be static?
    arch/arm/mach-omap2/board-omap4panda.c:464:6: warning: symbol 'omap4_panda_display_init' was not declared. Should it be static?
    arch/arm/mach-omap2/hsmmc.c:434:6: warning: symbol 'omap_init_hsmmc' was not declared. Should it be static?
    arch/arm/mach-omap2/hwspinlock.c:31:12: warning: symbol 'hwspinlocks_init' was not declared. Should it be static?
    arch/arm/mach-omap1/timer.c:58:12: warning: symbol 'omap1_dm_timer_init' was not declared. Should it be static?
    arch/arm/mach-omap1/fpga.c:90:6: warning: symbol 'innovator_fpga_IRQ_demux' was not declared. Should it be static?

Mark all of these as static.

Thanks to Arnd Bergmann <arnd@arndb.de> for pointing out a typo in the
original patch description.

3f8ddb032a Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/hwspinlock
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/hwspinlock:
  hwspinlock: add MAINTAINERS entries
  hwspinlock/omap: omap_hwspinlock_remove should be __devexit
  hwspinlock/u8500: add hwspinlock driver
  hwspinlock/core: register a bank of hwspinlocks in a single API call
  hwspinlock/core: remove stubs for register/unregister
  hwspinlock/core: use a mutex to protect the radix tree
  hwspinlock/core/omap: fix id issues on multiple hwspinlock devices
  hwspinlock/omap: simplify allocation scheme
  hwspinlock/core: simplify 'owner' handling
  hwspinlock/core: simplify Kconfig

Fix up trivial conflicts (addition of omap_hwspinlock_pdata, removal of
omap_spinlock_latency) in arch/arm/mach-omap2/hwspinlock.c

Also, do an "evil merge" to fix a compile error in omap_hsmmc.c which
for some reason was reported in the same email thread as the "please
pull hwspinlock changes".

c3c1250e93 hwspinlock/core/omap: fix id issues on multiple hwspinlock devices
hwspinlock devices provide system-wide hardware locks that are used
by remote processors that have no other way to achieve synchronization.

To achieve that, each physical lock must have a system-wide id number
that is agreed upon, otherwise remote processors can't possibly assume
they're using the same hardware lock.

Usually boards have a single hwspinlock device, which provides several
hwspinlocks, and in this case, they can be trivially numbered 0 to
(num-of-locks - 1).

In case boards have several hwspinlocks devices, a different base id
should be used for each hwspinlock device (they can't all use 0 as
a starting id!).

While this is certainly not common, it's just plain wrong to just
silently use 0 as a base id whenever the hwspinlock driver is probed.

This patch provides a hwspinlock_pdata structure, that boards can use
to set a different base id for each of the hwspinlock devices they may
have, and demonstrates how to use it with the omap hwspinlock driver.

While we're at it, make sure the hwspinlock core prints an explicit
error message in case an hwspinlock is registered with an id number
that already exists; this will help users catch such base id issues.

3528c58eb9 OMAP: omap_device: when building return platform_device instead of omap_device
All of the device init and device driver interaction with omap_device
is done using platform_device pointers.  To make this more explicit,
have omap_device return a platform_device pointer instead of an
omap_device pointer.

All current users of the omap_device pointer were only using it to get
at the platform_device pointer or struct device pointer, so fixing all
of the users was trivial.

This also makes it more difficult for device init code to directly
access members of struct omap_device, and allows for easier changing
of omap_device internals.

7bb412a642 omap: add hwspinlock device
Build and register an hwspinlock platform device.

Although only OMAP4 supports the hardware spinlock module (for now),
it is still safe to run this initcall on all omaps, because hwmod lookup
will simply fail on hwspinlock-less platforms.
