c8c9fda506 OMAP: PM: disable idle on suspend for GPIO and UART
Until these drivers are runtime PM converted, their device power
states are managed by calling custom driver hooks late in the
idle/suspend path.  Therefore, do not let the suspend/resume core code
automatically idle these devices since they will be managed manually
by the OMAP PM core very late in the idle/suspend path.

7b342a8d4c OMAP4: cm: Remove RESTORE macros to avoid access from SW
The restore part of the CM is an alias of some regular registers
used only during the SAR restore to facilate the dma to write
a contiguous set of registers.
The registers should never be used by the SW, only the original
register have to be used.

Remove them from cmX_44xx.h files to avoid anybody to use them by
mistake.

bc6149587b omap_hwmod: use a terminator record with omap_hwmod_dma_info arrays
Previously, struct omap_hwmod_dma_info arrays were unterminated; and
users of these arrays used the ARRAY_SIZE() macro to determine the
length of the array.  However, ARRAY_SIZE() only works when the array
is in the same scope as the macro user.

So far this hasn't been a problem.  However, to reduce duplicated
data, a subsequent patch will move common data to a separate, shared
file.  When this is done, ARRAY_SIZE() will no longer be usable.

This patch removes ARRAY_SIZE() usage for struct omap_hwmod_dma_info
arrays and uses a sentinel value (irq == -1) as the array terminator

6481c73c22 OMAP2+: hwmod: Enable module in shutdown to access sysconfig
When calling the shutdown, the module may be already in idle.
Accessing the sysconfig register will then lead to a crash.
In that case, re-enable the module in order to allow the access
to the sysconfig register.

c614ebf6f7 OMAP4: hwmod data: Add MSTANDBY_SMART_WKUP flag
Add the flag to every IPs that support it to allow the
framework to enable it instead of the SMART_STANDBY default
mode.
Without that, an IP with busmaster capability will not
be able to wakeup the interconnect at all.

724019b013 OMAP2+: hwmod: Fix smart-standby + wakeup support
The commit 86009eb326 was adding
the wakeup support for new OMAP4 IPs. This support is incomplete for
busmaster IPs that need as well to use smart-standby with wakeup.

This new standbymode is suported on HSI and USB_HOST_FS for the moment.

Add the new MSTANDBY_SMART_WKUP flag to mark the IPs that support this
capability.

Enable this new mode when applicable in _enable_wakeup, _disable_wakeup,
_enable_sysc and _idle_sysc.

The omap_hwmod_44xx_data.c will have to be updated to add this new flag.

7fa22bd546 ARM: 6993/1: platsmp: Allow secondary cpu hotplug with maxcpus=1
If an ARM system has multiple cpus in the same socket and the
kernel is booted with maxcpus=1, secondary cpus are possible but
not present due to how platform_smp_prepare_cpus() is called.
Since most typical ARM processors don't actually support physical
hotplug, initialize the present map to be equal to the possible
map in generic ARM SMP code. Also, always call
platform_smp_prepare_cpus() as long as max_cpus is non-zero (0
means no SMP) to allow platform code to do any SMP setup.

After applying this patch it's possible to boot an ARM system
with maxcpus=1 on the command line and then hotplug in secondary
cpus via sysfs. This is more in line with how x86 does things.

07ad6ab3d7 omap: drop __initdata tags from static struct platform_device declarations
Pointers to statically declared platform device structures which are
registered with platform_device_register() are then used during run time
to access these structure members, for example from platform_uevent()
and much more. Therefore, these structures should never be placed inside
sections which are dropped after boot. Fix platform devices incorrectly
tagged with __initdata which happen to exist inside OMAP sub-trees.

This bug has exhibited itself on my ARM/OMAP1 based Amstrad Delta
videophone after commit 6d3163ce86, "mm:
check if any page in a pageblock is reserved before marking it
MIGRATE_RESERVE", resulting in reading from several
/sys/device/platform/*/uevent files always ending up with segmentation
faults.

29cb3cd208 ARM: pm: allow suspend finisher to return error codes
There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.

Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack.  Also omit the tlb flush as no
changes to the page tables will have happened.
