Tony Lindgren 8280960181 ARM: OMAP: Remove cpu_is_omap usage from plat-omap/dma.c
This code will be eventually in drivers, and for the
code in the drivers we don't want to have any cpu_is_omap
usage. Those macros should be private to arch/arm/mach-omap1
and arch/arm/mach-omap2.

To fix this, let's move the define for dma_omap2plus()
to dma-omap.h, and use the existing dma_attr passed in
the platform_data as the revision registers are what they
are.

Note that we can now also remove the relative includes
introduced by the recent clean-up patches.

Tony Lindgren 32dee01e67 ARM: OMAP: Fix relative includes for debug-devices.h
As discussed on linux-arm-kernel, we want to avoid
relative includes for the arch/arm/*omap* shared code:

http://www.spinics.net/lists/linux-omap/msg80520.html

Let's add plat/debug-devices.h for debug_card_init()
to fix the relative includes.

Note that drivers must not use this header as it will
break build for omap2+ CONFIG_MULTIPLATFORM builds.

Tony Lindgren 5c2e88525b ARM: OMAP: Remove plat-omap/common.h
Most of the prototypes in plat-omap/common.h are not
common to omap1 and omap2+, they are local to omap2+
and should not be in plat-omap/common.h.

The only shared function prototype in this file is
omap_init_clocksource_32k(), let's put that into
counter-32k.h.

Note that the new plat/counter-32k.h must not be
included from drivers, that will break omap2+ build
for CONFIG_MULTIPLATFORM.

Tony Lindgren 6e740f9a85 ARM: OMAP: Move omap-pm-noop.c local to mach-omap2
This code should be private to mach-omap2.

The only use for it in for omap1 has been in dmtimer.c
to check for context loss. However, omap1 does not
lose context during idle, so the code is not needed.
Further, omap1 timer has OMAP_TIMER_ALWON set, so omap1
was not hitting omap_pm_get_dev_context_loss_count()
test.

Tony Lindgren c34f7c6962 ARM: OMAP: Make plat-omap/i2c.c port checks local
The common code should not have any omap1 or omap2+
specific code, and should not need to call the cpu_is_omap
macros.

The only remaining user for cpu_is_omap macros is
omap_i2c_nr_ports(). Let's make those checks in
the omap specific implementation of omap_i2c_add_bus()
instead in order to remove cpu_is_omap usage from
the common code.

Tony Lindgren bf027ca137 ARM: OMAP: Split sram.h to local headers and minimal shared header
Most of the defines are specific to omap1 and omap2+,
and should be in the local headers. Only minimal function
prototypes need to be shared.

As discussed on linux-arm-kernel, we want to avoid
relative includes for the arch/arm/*omap* shared code:

http://www.spinics.net/lists/linux-omap/msg80520.html

So this patch re-adds a minimal plat/sram.h.

The new plat/sram.h must not be included from drivers,
that will break build for omap2+ CONFIG_MULTIPLATFORM.

Note that this patch temporarily adds two more
relative includes; Those will be removed in the
following patch.

Paul Walmsley 5fb3d522ef ARM: OMAP2+: hwmod: add flag to prevent hwmod code from touching IP block during init
Add HWMOD_EXT_OPT_MAIN_CLK flag to indicate that this IP block is
dependent on an off-chip functional clock that is not guaranteed to be
present during initialization.  IP blocks marked with this flag are
left in the INITIALIZED state during kernel init.

This is a workaround for a hardware problem.  It should be possible to
guarantee that at least one clock source will be present and active
for any IP block's main functional clock.  This ensures that the hwmod
code can enable and reset the IP block.  Resetting the IP block during
kernel init prevents any bogus bootloader, ROM code, or previous OS
configuration from affecting the kernel.  Hopefully a clock
multiplexer can be added on future SoCs.

N.B., at some point in the future, it should be possible to query the
clock framework for this type of information.  Then this flag should
no longer be needed.

There's no need to keep the device related things in the

Note that as omap1 only has one i2c controller, we can
now remove the old device related macros.

There's no need to have this file in plat/fpga.h. We can

This patch converts vrfb library into a platform device, in an effort to
remove omap dependencies.

The platform device is registered in arch/arm/plat-omap/fb.c and
assigned resources depending on whether running on omap2 or omap3.

configuration registers and the vrfb virtual rotation areas.

Russell King b1b3f49ce4 ARM: config: sort select statements alphanumerically
As suggested by Andrew Morton:

  This is a pet peeve of mine.  Any time there's a long list of items
  (header file inclusions, kconfig entries, array initalisers, etc) and
  someone wants to add a new item, they *always* go and stick it at the
  end of the list.

  Guys, don't do this.  Either put the new item into a randomly-chosen
  position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically.  This commit was
created by the following perl:

while (<>) {
	while (/\\\s*$/) {
		$_ .= <>;
	}
	undef %selects if /^\s*config\s+/;
	if (/^\s+select\s+(\w+).*/) {
		if (defined($selects{$1})) {
			if ($selects{$1} eq $_) {
				print STDERR "Warning: removing duplicated $1 entry\n";
			} else {
				print STDERR "Error: $1 differently selected\n".
					"\tOld: $selects{$1}\n".
					"\tNew: $_\n";
				exit 1;
			}
		}
		$selects{$1} = $_;
		next;
	}
	if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
			  /^endif/ or /^endchoice/)) {
		foreach $k (sort (keys %selects)) {
			print "$selects{$k}";
		}
		undef %selects;
	}
	print;
}
if (%selects) {
	foreach $k (sort (keys %selects)) {
		print "$selects{$k}";
	}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)

Linus Torvalds 12250d843e Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Pull i2c-embedded changes from Wolfram Sang:
 "The changes for i2c-embedded include:

   - massive rework of the omap driver
   - massive rework of the at91 driver.  In fact, the old driver gets
     removed; I am okay with this approach since the old driver was
     depending on BROKEN and its limitations made it practically
     unusable, so people used bitbanging instead.  But even if there are
     users, there is no platform_data or module parameter which would
     need to be converted.  It is just another driver doing I2C
     transfers, just way better.  Modifications of arch/arm/at91 related
     files have proper acks from the maintainer.
   - new driver for R-Car I2C
   - devicetree and generic_clock conversions and fixes
   - usual driver fixes and changes.

  The rework patches have come a long way and lots of people have been
  involved in creating/testing them.  Most patches have been in
  linux-next at least since 3.6-rc5.  A few have been added in the last
  week, I have to admit.

  An unexpected (but welcome :)) peak in private life is the cause for
  that.  The "late" patches shouldn't cause any merge conflicts and I
  will have a special eye on them during the stabilization phase.  This
  is an exception and I want to have the patches in place properly in
  time again for the next kernels."

Linus Torvalds 5e090ed7af ARM: soc: late platform updates
This branch contains updates to OMAP and Marvell platforms (kirkwood,
 dove, mvebu) that came in after we had done the big multiplatform merges,
 so they were kept separate from the rest, and not separated into the
 traditional topics of cleanup/driver/platform features.
 
 For OMAP, the updates are:
 - Runtime PM conversions for the GPMC and RNG IP blocks
 - Preparation patches for the OMAP common clock framework conversion
 - clkdev alias additions required by other drivers
 - Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4
 - OMAP hwmod code and data improvements
 - Preparation patches for the IOMMU runtime PM conversion
 - Preparation patches for OMAP4 full-chip retention support
 
 For Kirkwood/Dove/mvebu:
 
 - New driver for "address decoder controller" for mvebu, which
   is a piece of hardware that configures addressable devices and
   peripherals. First user is the boot rom aperture on armada XP since
   it is needed for SMP support.
 - New device tree bindings for peripherals such as gpio-fan, iconnect
   nand, mv_cesa and the above address decoder controller.
 - Some defconfig updates, mostly to enable new DT boards and a few drivers.
 - New drivers using the pincontrol subsystem for dove, kirkwood and mvebu
 - New clean gpio driver for mvebu

Merge tag 'soc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull late ARM soc platform updates from Olof Johansson:
 "This branch contains updates to OMAP and Marvell platforms (kirkwood,
  dove, mvebu) that came in after we had done the big multiplatform
  merges, so they were kept separate from the rest, and not separated
  into the traditional topics of cleanup/driver/platform features.

  For OMAP, the updates are:
   - Runtime PM conversions for the GPMC and RNG IP blocks
   - Preparation patches for the OMAP common clock framework conversion
   - clkdev alias additions required by other drivers
   - Performance Monitoring Unit (PMU) support for OMAP2, 3, and
     non-4430 OMAP4
   - OMAP hwmod code and data improvements
   - Preparation patches for the IOMMU runtime PM conversion
   - Preparation patches for OMAP4 full-chip retention support

  For Kirkwood/Dove/mvebu:
   - New driver for "address decoder controller" for mvebu, which is a
     piece of hardware that configures addressable devices and
     peripherals.  First user is the boot rom aperture on armada XP
     since it is needed for SMP support.
   - New device tree bindings for peripherals such as gpio-fan, iconnect
     nand, mv_cesa and the above address decoder controller.
   - Some defconfig updates, mostly to enable new DT boards and a few
     drivers.
   - New drivers using the pincontrol subsystem for dove, kirkwood and
     mvebu
   - New clean gpio driver for mvebu"

Jean Pihet 3db11feffc ARM: OMAP: convert I2C driver to PM QoS for MPU latency constraints
Convert the driver from the outdated omap_pm_set_max_mpu_wakeup_lat
API to the new PM QoS API.
Since the constraint is on the MPU subsystem, use the PM_QOS_CPU_DMA_LATENCY
class of PM QoS. The resulting MPU constraints are used by cpuidle to
decide the next power state of the MPU subsystem.

The I2C device latency timing is derived from the FIFO size and the
clock speed and so is applicable to all OMAP SoCs.

Linus Torvalds 578f1ef91a MFD bits for the 3.7 merge window.
As usual we have a few new drivers:
 
 - TI LP8788
 - TI OMAP USB TLL
 - Maxim MAX8907
 - SMSC ECE1099
 - Dialog Semiconductor DA9055
 - A simpler syscon driver that allow us to get rid of the anatop one.
 
 Drivers are also gradually getting Device Tree and IRQ domain support.
 
 The following drivers got DT support:
 - palmas, 88pm860x, tc3589x and twl4030-audio
 
 And those ones now use the IRQ domain APIs:
 - 88pm860x, tc3589x, db8500_prcmu
 
 Also some other interesting changes:
 - Intel's ICH LPC now supports Lynx Point
 - TI's twl4030-audio added a GPO child
 - tps6527 enabled its backlight subdevice
 - The twl6030 pwm driver moved to the new PWM subsystem
 
 And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,
 ab8500, wm8994, wm5110, max8907 and the tps65xxx family.

Linus Torvalds 033d9959ed Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue changes from Tejun Heo:
 "This is workqueue updates for v3.7-rc1.  A lot of activities this
  round including considerable API and behavior cleanups.

   * delayed_work combines a timer and a work item.  The handling of the
     timer part has always been a bit clunky leading to confusing
     cancelation API with weird corner-case behaviors.  delayed_work is
     updated to use new IRQ safe timer and cancelation now works as
     expected.

   * Another deficiency of delayed_work was lack of the counterpart of
     mod_timer() which led to cancel+queue combinations or open-coded
     timer+work usages.  mod_delayed_work[_on]() are added.

     These two delayed_work changes make delayed_work provide interface
     and behave like timer which is executed with process context.

   * A work item could be executed concurrently on multiple CPUs, which
     is rather unintuitive and made flush_work() behavior confusing and
     half-broken under certain circumstances.  This problem doesn't
     exist for non-reentrant workqueues.  While non-reentrancy check
     isn't free, the overhead is incurred only when a work item bounces
     across different CPUs and even in simulated pathological scenario
     the overhead isn't too high.

     All workqueues are made non-reentrant.  This removes the
     distinction between flush_[delayed_]work() and
     flush_[delayed_]_work_sync().  The former is now as strong as the
     latter and the specified work item is guaranteed to have finished
     execution of any previous queueing on return.

   * In addition to the various bug fixes, Lai redid and simplified CPU
     hotplug handling significantly.

   * Joonsoo introduced system_highpri_wq and used it during CPU
     hotplug.

  There are two merge commits - one to pull in IRQ safe timer from
  tip/timers/core and the other to pull in CPU hotplug fixes from
  wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."

Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.

Tejun pointed out a few of them, I fixed a couple more.

Linus Torvalds 11801e9de2 ARM: soc: soc-specific updates
Most notable here is probably the addition of basic support for the
 BCM2835, an SoC used in some of the Roku 2 players as well as the
 much-hyped Raspberry Pi, cleaned up and contributed by Stephen
 Warren. It's still early days on mainline support, with just the
 basics working. But it has to start somewhere!
 
 Beyond that there's some conversions of clock infrastructure on tegra
 to common clock, misc updates for several other platforms, and OMAP
 now has its own bus (under drivers/bus) to manage its devices through.
 
 This branch adds two new directories outside of arch/arm:
 drivers/irqchip for new irq controllers, and drivers/bus for the above
 OMAP bus. It's expected that some of the other platforms will migrate

Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM soc-specific updates from Olof Johansson:
 "Most notable here is probably the addition of basic support for the
  BCM2835, an SoC used in some of the Roku 2 players as well as the
  much-hyped Raspberry Pi, cleaned up and contributed by Stephen Warren.
  It's still early days on mainline support, with just the basics
  working.  But it has to start somewhere!

  Beyond that there's some conversions of clock infrastructure on tegra
  to common clock, misc updates for several other platforms, and OMAP
  now has its own bus (under drivers/bus) to manage its devices through.

  This branch adds two new directories outside of arch/arm:
  drivers/irqchip for new irq controllers, and drivers/bus for the above
  OMAP bus.  It's expected that some of the other platforms will migrate
  parts of their platforms to those directories over time as well."

Fix up trivial conflicts with the clk infrastructure changes.

Jon Hunter 5c3e4ec485 ARM: OMAP: Add a timer attribute for timers that can interrupt the DSP
Some instances of the DMTIMER peripheral on OMAP devices have the ability
to interrupt the on-chip DSP in addition to the ARM CPU. Add a DMTIMER
attribute to indicate which timers can interrupt the DSP. By using the
omap_dm_timer_request_by_cap() API, driver will now be able to allocate
a DMTIMER that can interrupt the DSP based upon this attribute and not require
the driver to know which instance has this capability.

DMTIMERs that have the ability to interrupt the DSP on OMAP devices are as
follows ...

- OMAP1 (OMAP5912/16xx/17xx) devices	- All 8 DMTIMERs
- OMAP2/3/4 devices			- DMTIMERs 5-8

Please note that for OMAP3+, timer8 has the ability to interrupt the DSP and
generate a PWM output.

Tero Kristo 46b3af2789 ARM: OMAP4: hwmod: flag hwmods/modules not supporting module level context status
On OMAP4 most modules/hwmods support module level context status. On
OMAP3 and earlier, we relied on the power domain level context status.
Identify all modules that don't support 'context_offs' by adding a

Tero Kristo ce80979aed ARM: OMAP4: hwmod data: add support for lostcontext_mask
Currently hwmod only provides the offset for the context lose
register, and if we attempt to share the same register between two or
more hwmods, the resulting context loss counts get wrong. Thus, we
need a way to specify which bits are used for the context loss
information for each.  This is accomplished by adding a new field to
the omap4 prcm struct, 'lostcontext_mask', which specifies a bit-mask
to use for filtering the register.

Mark the affected hwmods appropriately.  'l4_abe' hwmod uses the
LOSTMEM_AESSMEM bit of RM_ABE_AESS_CONTEXT register, as l4_abe doesn't
have its own dedicated register for this purpose. This register is
shared with 'aess' hwmod, thus both hwmods must also specify which
bits of the register are used for them.

This patch only adds the hwmod data, but a future patch should add
code support such that only the specified bits are read and cleared by
the context lose counter update code. If a hwmod doesn't specify
'lostcontext_mask' (default behavior), the whole contents of the
context register should be used without any filtering.

Merge tag 'omap-devel-am33xx-for-v3.7' into test_v3.6-rc6_cff3.7_odaf3.7

From Paul Walmsley <paul@pwsan.com>:

AM33xx hwmod data and miscellaneous clock and hwmod fixes.  AM33xx
should now boot on mainline after this is applied, according to
Vaibhav.
2012-09-22 10:00:35 -06:00
Paul Walmsley 5dbd6535d5 These fixes are needed to fix non-omap build breakage for
twl-core driver and to fix omap1_defconfig compile when
 led driver changes and omap sparse IRQ changes are merged
 together. Also fix warnings for omaps not using pinctrl
 framework yet.

Tony Lindgren 68cb700c59 ARM: OMAP1: Move SoC specific headers from plat to mach for omap1
There's no need to have these in plat-omap any longer. Note that these
could eventually be made local to mach-omap1 instead of being in mach.

But to do that, at least various driver access using omap7xxx.h registers
needs to be fixed first.

Tony Lindgren dbc0416104 ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+
As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.

Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.

The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.

Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.

Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.

Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.

While at it, also sort some of the includes in the standard way.

Tony Lindgren 7d7e1eba7e ARM: OMAP2+: Prepare for irqs.h removal
As the interrupts should only be defined in the platform_data, and
eventually coming from device tree, there's no need to define them
in header files.

Let's remove the hardcoded references to irqs.h and fix up the includes
so we don't rely on headers included in irqs.h. Note that we're
defining OMAP_INTC_START as 0 to the interrupts. This will be needed
when we enable SPARSE_IRQ. For some drivers we need to add
#include <plat/cpu.h> for now until these drivers are fixed to
remove cpu_is_omapxxxx() usage.

While at it, sort som of the includes the standard way, and add
the trailing commas where they are missing in the related data
structures.

Note that for drivers/staging/tidspbridge we just define things
locally.

 Remove the ancient omap specific atags that are no longer needed.
 
 At some point we were planning to pass the bootloader information

 There's no need for these any longer as the kernel has been booting
 fine without them for quite some time. And Now we have device tree

Merge tags 'omap-devel-gpmc-fixed-for-v3.7' and 'cleanup-omap-tags-for-v3.7' into cleanup-sparseirq

Changes for GPMC (General Purpose Memory Controller) that take it
closer for being just a regular device driver.

Remove the ancient omap specific atags that are no longer needed.

At some point we were planning to pass the bootloader information
with custom atags that did not work out too well.

There's no need for these any longer as the kernel has been booting
fine without them for quite some time. And Now we have device tree
support that can be used instead.

Kevin Hilman 9634c8dd6a ARM: OMAP: omap_device: idle devices with no driver bound
Under some circumstances, drivers may leave an omap_device enabled due
to driver programming errors, or due to a failure in the drivers
probe method.

Using the recently added omap_device driver_status field, we can
detect conditions where an omap_device is enabled but has no driver
bound and then ensure that the device is properly idled until it can
be probed again.

The goal of this feature is not only to detect and warn on these error
conditions, but also to ensure that devices are properly put in
low-power states so they do not prevent SoC-wide low-power states.

Kevin Hilman 72bb6f9b51 ARM: OMAP: omap_device: don't attempt late suspend if no driver bound
Currently, the omap_device PM domain layer uses the late suspend and
early resume callbacks to ensure devices are in their low power
states.

However, this is attempted even in cases where a driver probe has
failed.  If a driver's ->probe() method fails, the driver is likely in
a state where it is not expecting its runtime PM callbacks to be
called, yet currently the omap_device PM domain code attempts to call
the drivers callbacks.

To fix, use the omap_device driver_status field to check whether a
driver is bound to the omap_device before attempting to trigger driver
callbacks.

Vaibhav Hiremath a2cfc509bc ARM: OMAP3+: hwmod: Add AM33XX HWMOD data
This patch adds HWMOD data for all the peripherals of
AM335X device and also hooks up to the existing OMAP framework.

hwmod data has been already been cleaned up for the recent
changes in clocktree, where all leaf nodes have been removed,
since with modulemode based control, both clock and hwmod
interface does same thing. This reduces the code size to large
extent and also avoids duplication of same control.
So instead of specifying module's leaf node as a main_clk,
now we are relying on parent clock of module's functional clock.

Vaibhav Hiremath b82b04e8eb ARM: OMAP: omap_device: Do not overwrite resources allocated by OF layer
With the new devices (like, AM33XX and OMAP5) we now only support
DT boot mode of operation and now it is the time to start killing
slowly the dependency on hwmod, so with this patch, we are starting
with device resources.
The idea here is implemented considering to both boot modes -
  - DT boot mode
    OF framework will construct the resource structure (currently
    does for MEM & IRQ resource) and we should respect/use these
    resources, killing hwmod dependency.
    If pdev->num_resources > 0, we assume that MEM & IRQ resources
    have been allocated by OF layer already (through DTB).

    Once DMA resource is available from OF layer, we should
    kill filling any resources from hwmod.

  - Non-DT boot mode
    Here, pdev->num_resources = 0, and we should get all the
    resources from hwmod (following existing steps)

Peter Ujfalusi 3956a1a0d1 ARM: OMAP: omap_device: Fix up resource names when booted with devicetree
When booted with some resource will have their name set to NULL. This can
cause later kernel crash since this is not expected by the platform code.

When we boot without DT the devices are created with platform_device_add()
which itself fixes up the missing resource names:
if (r->name == NULL)
	r->name = dev_name(&pdev->dev);

The of core also fixes up the resource names when taking the information
from DT data - in __of_address_to_resource():
r->name = name ? name : dev->full_name;

When we boot OMAP with devicetree: of will create the devices based on the
DT data so the resource names are guarantied to be not NULL. Since we have
the 'ti,hwmod' tag, we remove the of created resources from the device and
re-create them based on hwmod data. If the hwmod data does not specify a
name for a resource it will be NULL.
This can cause kernel crash if the driver uses
platform_get_resource_byname() to get any resource.

In some OMAP3 HS devices (at least Nokia N9 and N950), the public SRAM
seems to conflict with secure portition of SRAM. When booting the 3.6-rc3
kernel (and also earlier) on these devices, the kernel gets tainted with

Fix this by skipping the first 16K of the public SRAM. (Note that the
mapping could not be changed, as it resulted in secure monitor call
failure in save_secure_sram().)

This will leave 12K SRAM available that should be still sufficient. The
patch has been boot tested with vanilla 3.6-rc3 on N900, N950 and N9.

From Bryan Wu <bryan.wu@canonical.com>:

Based on Linus Walleij's ARM LED consolidation work, this patchset introduce a
new generic led trigger for CPU not only for ARM but also for others.

For enabling CPU idle event, CPU arch code should call ledtrig_cpu() stub to
trigger idle start or idle end event.

These patches convert old style LED driver in arch/arm to gpio_led or new led
driver interface. Against 3.5 release and build successfully for all the machines.

Test ledtrig-cpu driver on OMAP4 Panda board.

v9 --> v10
 * fix compiling issue on versatile_defconfig reported by Russell King
 * rebase to 3.5 kernel and move patches to new git tree

v8 --> v9:

 * add a new struct led_trigger_cpu
 * add lock_is_inited to record mutex lock initialization

v6 --> v7:

 * fix some typo pointed
 * use BUG_ON to detect CPU numbers during building stage

v5 --> v6:
 * replace  __get_cpu_var() to per_cpu()
 * remove smp_processor_id() which is wrong with for_each_possible_cpu()
 * test on real OMAP4 Panda board
 * add comments about CPU hotplug in the CPU LED trigger driver

v4 --> v5:
 * rebase all the patches on top of latest linux-next
 * replace on_each_cpu() with for_each_possible_cpu()
 * add some description of ledtrig_cpu() API
 * remove old leds code from driver nwflash.c, which should use a new led trigger then
 * this trigger driver can be built as module now

v3 --> v4:
 * fix a typo pointed by Jochen Friedrich
 * fix some building errors

Timo Kokkonen c5491d1ae1 ARM: OMAP: dmtimers: Fix locking issue in omap_dm_timer_request*()
Calling omap_dm_timer_prepare while the spinlock is held is not
allowed as sleeping functions are called later on during the
preparation (namely within clk_get()).

dm_timer_lock is only required for protecting the
omap_timer_list. After the timer is marked as reserved, the lock is no
longer needed and should be freed.

AM33XX device falls under omap2 class, so make cpu_class_is_omap2()
macro true by adding soc_is_am33xx() to existing list of cpu/soc
check.

This is required to unblock the basic boot support on AM335x platform.

Jan Luebbe 6c691b5df1 omap: Fix multi.h when only ARCH_OMAP3 and SOC_AM33XX are selected
When only ARCH_OMAP3 (or -2,-4,...) and SOC_AM33XX are selected, multi.h
doesn't set MULTI_OMAP2. In this case, cpu.h will simply define
cpu_is_omap24xx() as 1.

This causes problems for example for omap_hwmod.c:omap_hwmod_init which
checks for cpu_is_omap24xx() first, using the wrong soc_ops for AM33xx.

Fix this by defining MULTI_OMAP2 when using SOC_AM33XX together with
something else.

Jon Hunter 54f32a35f4 ARM: OMAP2+: Fix dmtimer set source clock failure
Calling the dmtimer function omap_dm_timer_set_source() fails if following a
call to pm_runtime_put() to disable the timer. For example the following
sequence would fail to set the parent clock ...

	omap_dm_timer_stop(gptimer);
	omap_dm_timer_set_source(gptimer, OMAP_TIMER_SRC_32_KHZ);

The following error message would be seen ...

omap_dm_timer_set_source: failed to set timer_32k_ck as parent

The problem is that, by design, pm_runtime_put() simply decrements the usage
count and returns before the timer has actually been disabled. Therefore,
setting the parent clock failed because the timer was still active when the
trying to set the parent clock. Setting a parent clock will fail if the clock
you are setting the parent of has a non-zero usage count. To ensure that this
does not fail use pm_runtime_put_sync() when disabling the timer.

Note that this will not be seen on OMAP1 devices, because these devices do
not use the clock framework for dmtimers.

Linus Torvalds a6dc77254b Merge branch 'dmaengine' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM DMA engine updates from Russell King:
 "This looks scary at first glance, but what it is is:
   - a rework of the sa11x0 DMA engine driver merged during the previous
     cycle, to extract a common set of helper functions for DMA engine
     implementations.
   - conversion of amba-pl08x.c to use these helper functions.
   - addition of OMAP DMA engine driver (using these helper functions),
     and conversion of some of the OMAP DMA users to use DMA engine.

  Nothing in the helper functions is ARM specific, so I hope that other
  implementations can consolidate some of their code by making use of
  these helpers.

  This has been sitting in linux-next most of the merge cycle, and has
  been tested by several OMAP folk.  I've tested it on sa11x0 platforms,
  and given it my best shot on my broken platforms which have the
  amba-pl08x controller.

  The last point is the addition to feature-removal-schedule.txt, which
  will have a merge conflict.  Between myself and TI, we're planning to
  remove the old TI DMA implementation next year."

Vaibhav Hiremath 971b8a9c3e ARM: OMAP2+: am33xx: Change cpu_is_am33xx to soc_is_am33xx
As per recent discussion on the linux-omap list, we are
moving in the direction where, we will have only architecture,
ARCH_OMAP2PLUS and all devices/platforms will be treated
as a SoC underneath.

So the first step in this direction is to adopt this change
for all new devices getting in, converting
cpu_is_am33xx/335x() ==> soc_is_am33xx/335x()

Vaibhav Hiremath 1c213ba16e ARM: OMAP2+: am33xx: Make am33xx as a separate class
Initially, we decided to make am33xx family of device to fall
under omap3 class (cpu_is_omap34xx() = true), since it carries
Cortex-A8 core. But while adding complete baseport support
(like, clock, power and hwmod) support, it is observed that,
we are creating more and more problems by treating am33xx device
as omap3 family, as nothing matches between them
(except cortex-A8 mpu).

So,  after long discussion we have came to the conclusion that,
we should not consider am33xx device as omap3 family, instead
create separate class (SOC_AM33XX) under OMAP2PLUS.
This means, for am33xx device, cpu_is_omap34xx() will return false,
and only cpu_is_am33xx() will be true.

Kishon Vijay Abraham I 6668546f3b ARM: OMAP2+: hwmod code: add support to set dmadisable in hwmod framework
The DMADISABLE bit is a semi-automatic bit present in sysconfig register
of some modules. When the DMA must perform read/write accesses, the
DMADISABLE bit is cleared by the hardware. But when the DMA must stop for power
management, software must set the DMADISABLE bit back to 1.

In cases where the ROMCODE/BOOTLOADER uses dma, the hardware clears the
DMADISABLE bit (but the romcode/bootloader might not set it back to 1).
In order for the kernel to start in a clean state, it is
necessary for the kernel to set DMADISABLE bit back to 1 (irrespective
of whether it's been set to 1 in romcode or bootloader).

During _reset of the (hwmod)device, the DMADISABLE bit is set so that it
does not prevent idling of the system. (NOTE: having DMADISABLE to 0,
prevents the system to idle)

DMADISABLE bit is present in usbotgss module of omap5.

Tarun Kanti DebBarma bed9d1bb4e ARM: OMAP2+: hwmod: add omap_hwmod_get_main_clk() API
Add an API to get main clock name associated with a given @oh.
This will avoid the need to construct fclk names during early
initialization in order to get fclk handle using clk_get().

Vaibhav Hiremath 768c69f5e9 ARM: OMAP3/4: omap_hwmod: Add rstst_offs field to struct omap_hwmod_omap4_prcm
In case of AM33XX device, XXX_RSTST register offset is not
consistent across PRM modules/instances,

PRM_XXX            RSTST
=========================
PRM_PER_MOD:       0x04
PRM_WKUP_MOD:      0x0C
PRM_MPU_MOD:       NA
PRM_DEVICE_MOD:    0x08

This means, we need to pass on XXX_RSTST register offset
information through omap_hwmod data, similar to XXX_RSTCTRL.

Currently, this field is only applicable and used for AM33XX
devices.
