R Sricharan e799840a09 ARM: OMAP2+: Move stubbed secure_sram_reserve function to a common.c and call it __weak
omap_secure_ram_reserve_memblock is stubbed for OMAP1,2 only builds using a
 ifdef check. But this results in adding CONFIG_ARCH_OMAPxx checks for
future socs that use the real function. So move this to common.c file and
call it __weak.

Commit ac5b0ea3d (Merge tag 'omap-devel-f-for-3.6'...) had a merge
conflict that somehow got incorrecly resolved in a lossy way for
commit bed9d1bb (ARM: OMAP2+: hwmod: add omap_hwmod_get_main_clk() API).
Fix the issue by applying the missing pieces.

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.

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.

Tony Lindgren 3f96a2d90e Here is some more omap clean-up. The biggest changes are
hwmod, clock, and System Control Module cleanup, and the removal
 of the last instance of omap_read/write usage for omap2+ with
 the removal of unused USB OHCI Full Speed driver support. The
 removed OHCI is only currently used for omap1 as the actively
 used omap2+ boards have either MUSB or another instance of
 OHCI+EHCI that's more usable.

Vaibhav Hiremath e30384abd6 ARM: OMAP3+: clock33xx: Add AM33XX clock tree data
AM33XX clock implementation is different than any existing OMAP
family of devices. Although DPLL module is similar to OMAP4
device, but the usage is very much different than OMAP4.
AM33XX has different peripheral set and each module gets
integrated to the clock framework differently than OMAP
family of devices.

This patch adds full Clock tree data for AM33XX family
of devices and also integrates it into existing OMAP framework.

Now that OMAP730 and OMAP850 support is mostly unified, there's no
need for separate cpu detection macros for these architectures. At
least, currently there isn't, because both macros are unused.
cpu_is_7xx() seems to cover all possible uses.

No file includes omap730.h or omap850.h. That's not surprising, as
commit e6684f7132 ("OMAP7XX: Create

omap850.h", while all "values defined [in omap7xx.h] are identical to
those in both the old files". So it seems it was just an oversight to
keep both the old files after commit
7a8f48f8c6 ("OMAP7XX: omap_uwire.c:

Jon Hunter 2b2d352300 ARM: OMAP2+: Move dmtimer clock set function to dmtimer driver
OMAP1 uses an architecture specific function for setting the dmtimer clock
source, where as the OMAP2+ devices use the clock framework. Eventually OMAP1
device should also use the clock framework and hence we should not any
architecture specific functions.

For now move the OMAP2+ function for configuring the clock source into the
dmtimer driver. Therefore, we do no longer need to specify an architecture
specific function for setting the clock source for OMAP2+ devices. This will
simplify device tree migration of the dmtimers for OMAP2+ devices.

From now on, only OMAP1 devices should specify an architecture specific
function for setting the clock source via the platform data set_dmtimer_src()
function pointer.

Jon Hunter 0b30ec1cb7 ARM: OMAP: Remove timer function pointer for context loss counter
For OMAP2+ devices, a function pointer that returns the number of times a timer
power domain has lost context is passed to the dmtimer driver. This function
pointer is only populated for OMAP2+ devices and it is pointing to a platform
function. Given that this is a platform function, we can simplify the code by
removing the function pointer and referencing the function directly. We can use
the OMAP_TIMER_ALWON flag to determine if we need to call this function for
OMAP1 and OMAP2+ devices.

The benefit of this change is the we can remove the function pointer from the
platform data and simplifies the dmtimer migration to device-tree.

Jon Hunter 1c2d076b58 ARM: OMAP: Remove loses_context variable from timer platform data
The platform data variable loses_context is used to determine if the timer may
lose its logic state during power transitions and so needs to be restored. This
information is also provided in the HWMOD device attributes for OMAP2+ devices
via the OMAP_TIMER_ALWON flag. When this flag is set the timer will not lose
context. So use the HWMOD device attributes to determine this.

For OMAP1 devices, loses_context is never set and so set the OMAP_TIMER_ALWON
flag for OMAP1 timers to ensure that code is equivalent.

Jon Hunter 67d2e760ae ARM: OMAP2+: Fix external clock support for dmtimers
Currently, the dmtimer determines whether an timer can support an external
clock source (sys_altclk) for driving the timer by the IP version. Only
OMAP24xx devices can support an external clock source, but the IP version
between OMAP24xx and OMAP3xxx is common and so this incorrectly indicates
that OMAP3 devices can use an external clock source.

Rather than use the IP version, just let the clock framework handle this.
If the "alt_ck" does not exist for a timer then the clock framework will fail
to find the clock and hence will return an error. By doing this we can eliminate
the "timer_ip_version" variable passed as part of the platform data and simplify
the code.

We can also remove the timer IP version from the HWMOD data because the dmtimer
driver uses the TIDR register to determine the IP version.

Jon Hunter d1c1691be5 ARM: OMAP: Add DMTIMER capability variable to represent timer features
Although the OMAP timers share a common hardware design, there are some
differences between the timer instances in a given device. For example, a timer
maybe in a power domain that can be powered-of, so can lose its logic state and
need restoring where as another may be in power domain that is always be on.
Another example, is a timer may support different clock sources to drive the
timer. This information is passed to the dmtimer via the following platform data
structure.

struct dmtimer_platform_data {
	int (*set_timer_src)(struct platform_device *pdev, int source);
	int timer_ip_version;
	u32 needs_manual_reset:1;
	bool loses_context;
	int (*get_context_loss_count)(struct device *dev);
};

The above structure uses multiple variables to represent the timer features.
HWMOD also stores the timer capabilities using a bit-mask that represents the
features supported. By using the same format for representing the timer
features in the platform data as used by HWMOD, we can ...

1. Use the flags defined in the plat/dmtimer.h to represent the features
   supported.
2. For devices using HWMOD, we can retrieve the features supported from HWMOD.
3. Eventually, simplify the platform data structure to be ...

struct dmtimer_platform_data {
	int (*set_timer_src)(struct platform_device *pdev, int source);
	u32 timer_capability;
}

Another benefit from doing this, is that it will simplify the migration of the
dmtimer driver to device-tree. For example, in the current OMAP2+ timer code the
"loses_context" variable is configured at runtime by calling an architecture
specific function. For device tree this creates a problem, because we would need
to call the architecture specific function from within the dmtimer driver.
However, such attributes do not need to be queried at runtime and we can look up
the attributes via HWMOD or device-tree.

This changes a new "capability" variable to the platform data and timer
structure so we can start removing and simplifying the platform data structure.

Jon Hunter b7b4ff764f ARM: OMAP2+: Add dmtimer platform function to reserve systimers
During early boot, one or two dmtimers are reserved by the kernel as system
timers (for clocksource and clockevents). These timers are marked as reserved
and the dmtimer driver is notified which timers have been reserved via the
platform data information.

For OMAP2+ devices the timers reserved may vary depending on device and compile
flags. Therefore, it is not easy to assume which timers we be reserved for the
system timers. In order to migrate the dmtimer driver to support device-tree we
need a way to pass the timers reserved for system timers to the dmtimer driver.
Using the platform data structure will not work in the same way as it is
currently used because the platform data structure will be stored statically in
the dmtimer itself and the platform data will be selected via the device-tree
match device function (of_match_device).

There are a couple ways to workaround this. One option is to store the system
timers reserved for the kernel in the device-tree and query them on boot.
The downside of this approach is that it adds some delay to parse the DT blob
to search for the system timers. Secondly, for OMAP3 devices we have a
dependency on compile time flags and the device-tree would not be aware of that
kernel compile flags and so we would need to address that.

The second option is to add a function to the dmtimer code to reserved the
system timers during boot and so the dmtimer knows exactly which timers are
being used for system timers. This also allows us to remove the "reserved"
member from the timer platform data. This seemed like the simpler approach and
so was implemented here.

Merge tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6

Pull GPIO driver changes from Grant Likely:
 "Lots of gpio changes, both to core code and drivers.

  Changes do touch architecture code to remove the need for separate
  arm/gpio.h includes in most architectures.

  Some new drivers are added, and a number of gpio drivers are converted
  to use irq_domains for gpio inputs used as interrupts.  Device tree
  support has been amended to allow multiple gpio_chips to use the same
  device tree node.

  Remaining changes are primarily bug fixes."

Ivan Djelic 8d602cf50d ARM: OMAP3: gpmc: add BCH ecc api and modes
This patch adds a simple BCH ecc computation api, similar to the
existing Hamming ecc api. It is intended to be used by the MTD layer.
It implements the following features:

- support 4-bit and 8-bit ecc computation
- do not protect user bytes in spare area, only data area is protected
- ecc for an erased NAND page (0xFFs) is also a sequence of 0xFFs

This last feature is obtained by adding a constant polynomial to
the hardware computed ecc. It allows to correct bitflips in blank pages
and is extremely useful to support filesystems such as UBIFS, which expect
erased pages to contain only 0xFFs.

This api has been tested on an OMAP3630 board.

Artem: The OMAP maintainer Tony Lindgren gave us his blessing for merging
this patch via the MTD tree.

Note that this depends on a fix in omap-fixes-non-critical-for-v3.5,
so it's based on that.

Tarun Kanti DebBarma e953e305d5 ARM: OMAP2+: dmtimer: remove redundant sysconfig context restore
Since hwmod framework now manages sysconfig context save/restore
there is no more need to touch this register in driver. Hence,
remove restore of sysconfig register in omap_timer_restore_context.
This was causing incorrect context restore of sysconfig register.

Kevin Hilman 68a88b9887 ARM: OMAP: AM35xx: convert 3517 detection/flags to AM35xx
Currently cpu_is_omap3517() actually detects any device in the AM35x
family (3517 and no-SGX version 3505.)  To make it more clear what is
being detected, convert the names from 3517 to AM35xx.

This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517().
In order to avoid cross-tree dependencies with clock-tree changes,
cpu_is_omap3517() is left until the clock changes are merged,
at which point cpu_is_omap3517() will be completely removed.

Vaibhav Hiremath 1fe97c8f6a ARM: OMAP: Make OMAP clocksource source selection using kernel param
Current OMAP code supports couple of clocksource options based
on compilation flag (CONFIG_OMAP_32K_TIMER). The 32KHz sync-timer
and a gptimer which can run on 32KHz or system clock (e.g 38.4 MHz).
So there can be 3 options -

1. 32KHz sync-timer
2. Sys_clock based (e.g 13/19.2/26/38.4 MHz) gptimer
3. 32KHz based gptimer.

The optional gptimer based clocksource was added so that it can
give the high precision than sync-timer, so expected usage was 2
and not 3.
Unfortunately option 2, clocksource doesn't meet the requirement of
free-running clock as per clocksource need. It stops in low power states
when sys_clock is cut. That makes gptimer based clocksource option
useless for OMAP2/3/4 devices with sys_clock as a clock input.
So, in order to use option 2, deeper idle state MUST be disabled.

Option 3 will still work but it is no better than 32K sync-timer
based clocksource.

We must support both sync timer and gptimer based clocksource as
some OMAP based derivative SoCs like AM33XX does not have the
sync timer.

Considering above, make sync-timer and gptimer clocksource runtime
selectable so that both OMAP and AMXXXX continue to use the same code.

And, in order to precisely configure/setup sched_clock for given
clocksource, decision has to be made early enough in boot sequence.

So, the solution is,

Use standard kernel parameter ("clocksource=") to override
default 32k_sync-timer, in addition to this, we also use hwmod database
lookup mechanism, through which at run-time we can identify availability
of 32k-sync timer on the device, else fall back to gptimer.

Also, moved low-level SoC specific init code to respective files,
(mach-omap1/timer32k.c and mach-omap2/timer.c)

Merge tag 'omap-cleanup-b-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into cleanup-hwmod

Clean up various aspects of the OMAP hwmod code, which is the IP block
control code for OMAP SoCs.  In particular, this series results in
a considerable diffstat savings by changing the way that IP block
interconnections are defined.

Paul Walmsley 42b9e38728 ARM: OMAP4: hwmod data: add some interconnect-related IP blocks
Add the SL2 interface IP block and interconnect data.  The SL2 is related
to the IVA-HD subsystem.

Add IP block and interconnect data for the C2C ("Chip-to-chip")
interconnect.  This can provide a direct system interconnect link to
other devices stacked on the OMAP package.

Add the ELM IP block and interconnect data.  The ELM can be used
to locate errors in NAND flash connected to the GPMC.

Paul Walmsley 2221b5cddc ARM: OMAP2+: hwmod: add support for link registration
Add support for direct IP block interconnect ("link") registration to
the hwmod code via a new function, omap_hwmod_register_links().  This
will replace direct registration of hwmods, and a subsequent patch
will remove omap_hwmod_register().

This change will allow a subsequent patch to remove the hwmod data
link arrays.  This will reduce the size of the hwmod static data and
also make it easier to generate the data files.  It will also make it
possible to share some of the struct omap_hwmod records across
multiple SoCs, since the link array pointers will be removed from the
struct omap_hwmod.

The downside is that boot time will increase.  Minimizing boot time
was the reason why the link arrays were originally introduced.
Removing them will require extra computation during boot to allocate
memory and associate IP blocks with their interconnects.  However,
since the current kernel development focus is on reducing the number
of lines in arch/arm/mach-omap2/, boot time impact is now seemingly
considered a lower priority.

This patch contains additional complexity to reduce the number of
memory allocations required for this change.  This reduces the boot
time impact: total hwmod link registration time was ~ 2655
microseconds with a simple allocation strategy, but is now ~ 549
microseconds[1] with the approach taken by this patch.

1. Measured on a BeagleBoard 35xx @ 500MHz MPU/333 MHz CORE, average
   of 7 samples.  Total uncertainty is +/- 61 microseconds.

Paul Walmsley 515237d6fe ARM: OMAP2+: hwmod: extend OCP_* register offsets from 16 to 32 bits
Extend the OCP_* register offsets in the struct
omap_hwmod_class_sysconfig to 32 bits.  This is required to add the
OMAP4+ GPU hwmod, which uses OCP_* register offsets larger than 16
bits.

Another possible solution may be to simply add a single 16 bit offset
field in this structure, and to add code to factor that offset into
all OCP_* register accesses.  This would save some memory, since
almost no modules need 32 bit offsets.

Paul Walmsley 3d10f0d6d9 ARM: OMAP4: hwmod data: add OCP_USER_DSP; mark omap44xx_dsp__iva appropriately
One of the OMAP4 links was missing OCP_USER flags, since it was only
used by the DSP initiator, and we did not have an OCP_USER_DSP flag.
Future patches will switch the hwmod code and data to register
interfaces, rather than hwmods, and it will be mandatory for all
interfaces to have at least one user bit set.  This patch resolves the
issue by adding OCP_USER_DSP and marking the DSP-IVA interface
appropriately.

The timer integration code pokes around in hwmod data structures.
Those data structures are about to change.  Define a function,
omap_hwmod_get_resource_byname(), for the timer integration code to
use instead.

The original patch has been changed to use struct resource by Tony's
request, although the caller of this function should not be a driver._
Platform drivers should get their data through the regular platform_*
functions; DT drivers through the appropriate of_* functions.  This a
function is only for use by OMAP core code in arch/arm/*omap*.

Paul Walmsley d3645d39ad ARM: OMAP1: OHCI: use platform_data fn ptr to enable OCPI bus
The OMAP1 OHCI driver needs to enable the OCPI IP block before it can
work.  Previously, the driver was simply calling a symbol defined in
the OMAP platform code, but this is incorrect: drivers should be fully
decoupled from platform and architecture code.

So instead, modify the driver to call through a platform_data function
pointer instead.  We skip any DT aspect, since OMAP1 is not scheduled
to be converted to DT in the near future.

This resolves the following sparse warning:

It also gets rid of a cpu_is_omap16xx() call in a driver.

In the long term, it probably makes sense to move the OCPI bus code to
somewhere under drivers/.  This should avoid the whole platform_data/DT
issue with this function.

Fernando Guzman Lugo d99de7f552 ARM: OMAP2+: hwmod: add softreset delay field and OMAP4 data
Due to HW limitation, some IPs should not be accessed just after a
softreset. Since the current hwmod sequence is accessing the sysconfig
register just after the reset, it might lead to OCP bus error in
that case.

Add a new field in the sysconfig structure to specify a delay in usecs
needed after doing a softreset.

In the case of the ISS and FDIF modules, the L3 OCP port will be
disconnected upon a SW reset. That issue was confirmed with HW simulation
and an errata should be available soon. The HW recommendation to avoid
that is to wait for 100 OCP clk cycles, before accessing the IP.

Considering the worse case (OPP50), the L3 bus will run at 100 MHz,
so a 1 usec delay is needed. Add an x2 margin to be safe.

Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: cleanups of io includes" from Olof Johansson:
 "Rob Herring has done a sweeping change cleaning up all of the
  mach/io.h includes, moving some of the oft-repeated macros to a common
  location and removing a bunch of boiler plate.  This is another step
  closer to a common zImage for multiple platforms."

Fix up various fairly trivial conflicts (<mach/io.h> removal vs changes
around it, tegra localtimer.o is *still* gone, yadda-yadda).

 maintainer for the driver, or the maintainer prefers to have the
 platform changes in the same branch as the driver changes, the patches
 to the drivers are included as well.
 
 A much smaller set of driver updates that depend on other branches
 getting merged first will be sent later.
 
 The new export of tegra_chip_uid conflicts with other changes in fuse.c.
 In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with

Linus Torvalds 46b407ca4a remoteproc/rpmsg: new subsystem
This new subsystem provides a common way to talk to secondary processors
 on an SoC, e.g. a DSP, GPU or service processor, using virtio as the
 transport. In the long run, it should replace a few dozen vendor
 specific ways to do the same thing, which all never made it into the
 upstream kernel. There is a broad agreement that rpmsg is the way to
 go here and several vendors have started working on replacing their
 own subsystems.
 
 Two branches each add one virtio protocol number. Fortunately the
 numbers were agreed upon in advance, so there are only context changes.

Linus Torvalds 281b05392f ARM: SoC specific updates
These changes are all specific to an soc family or the code for
 one soc. Lots of work for Tegra3 this time, but also a lot of other
 platforms. There will be another (smaller) set of soc patches later in
 the merge window for stuff that has dependencies on external trees or
 that was sent just before the merge window opened.
 
 The asoc tree added a few devices to the i.mx platform, which conflict
 with other devices added in the same place here.
 
 The tegra Makefile conflicts between a number of branches, mostly because
 of changes regarding localtimer.c, which was removed in the end.

Linus Torvalds b2094ef840 Updates of sound stuff for 3.4-rc1
Here is the first big update chunk of sound stuff for 3.4-rc1.
 
 In the common sound infrastructure, there are a few changes for
 dynamic PCM support (used in ASoC) and a few clean-ups.  Majority of
 changes are found, as usual, in HD-audio and ASoC.
 
 Some highlights of HD-audio changes:
 - All the long-standing static quirk codes for Realtek codec were
 finally removed by fixing and extending the Realtek auto-parser.
 
 - The mute-LED control is standardized over all HD-audio codec
   drivers using the extended vmaster hook.
 
 - The vmaster slave mixer elements are initialized to 0dB as default
   so that the user won't be annoyed by the silent output after
   updates, e.g. due to the additions of new elements.
 
 - Other many fix-ups for the misc HD-audio devices.
 
 In the ASoC side, this is a very active release, including a quite a
 few framework enhancements.  Some highlights:
 
 - Support for widgets not associated with a CODEC, an important part
   of the dynamic PCM framework.
 
 - A library factoring out the common code shared by dmaengine based
   DMA drivers contributed by Lars-Peter Clausen.  This will save a lot
   of code and make it much easier to deploy enhancements to
   dmaengine.
 
 - Support for binary controls, used for providing runtime
   configuration of algorithm coefficients.
 
 - A new DAPM widget type for regulator supplies allowing drivers for
   devices that can power down unused supplies while active to do
   without any per-driver code.
 
 - DAPM widgets for DAIs, initially giving a speed boost for playback
   startup and shutdown and also the basis for CODEC<->CODEC DAI link
   support.
 
 - Support for specifying the number of significant bits on audio
   interfaces, useful for allowing applications to know how much effort
   to put into generating data for a larger sample format.
 
 - Conversion of the FSI driver used on some SH processors to
   DMAEngine.
 
 - Conversion of EP93xx drivers to DMAEngine.
 
 - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
   WM2200.
 
 - Move audmux driver from arc/arm to sound/soc
 
 - McBSP move from arch/ to sound/ and updates
 
 Also, a few small updates and fixes for other drivers like au88x0,
 ymfpci, USB 6fire, USB usx2yaudio are included.

Merge tag 'sound-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull updates of sound stuff from Takashi Iwai:
 "Here is the first big update chunk of sound stuff for 3.4-rc1.

  In the common sound infrastructure, there are a few changes for
  dynamic PCM support (used in ASoC) and a few clean-ups.  Majority of
  changes are found, as usual, in HD-audio and ASoC.

  Some highlights of HD-audio changes:

   - All the long-standing static quirk codes for Realtek codec were
     finally removed by fixing and extending the Realtek auto-parser.

   - The mute-LED control is standardized over all HD-audio codec
     drivers using the extended vmaster hook.

   - The vmaster slave mixer elements are initialized to 0dB as default
     so that the user won't be annoyed by the silent output after
     updates, e.g.  due to the additions of new elements.

   - Other many fix-ups for the misc HD-audio devices.

  In the ASoC side, this is a very active release, including a quite a
  few framework enhancements.  Some highlights:

   - Support for widgets not associated with a CODEC, an important part
     of the dynamic PCM framework.

   - A library factoring out the common code shared by dmaengine based
     DMA drivers contributed by Lars-Peter Clausen.  This will save a
     lot of code and make it much easier to deploy enhancements to
     dmaengine.

   - Support for binary controls, used for providing runtime
     configuration of algorithm coefficients.

   - A new DAPM widget type for regulator supplies allowing drivers for
     devices that can power down unused supplies while active to do
     without any per-driver code.

   - DAPM widgets for DAIs, initially giving a speed boost for playback
     startup and shutdown and also the basis for CODEC<->CODEC DAI link
     support.

   - Support for specifying the number of significant bits on audio
     interfaces, useful for allowing applications to know how much
     effort to put into generating data for a larger sample format.

   - Conversion of the FSI driver used on some SH processors to
     DMAEngine.

   - Conversion of EP93xx drivers to DMAEngine.

   - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
     WM2200.

   - Move audmux driver from arc/arm to sound/soc

   - McBSP move from arch/ to sound/ and updates

  Also, a few small updates and fixes for other drivers like au88x0,
  ymfpci, USB 6fire, USB usx2yaudio are included."

The conflicts with pxa are non-obvious, we have multiple branches
adding and removing the same clock settings. According to
Haojian Zhuang, removing the sa1100 rtc dummy clock is the correct
fix here.

Rob Herring 6f6f6a7029 ARM: create a common IOMEM definition
Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

Peter Ujfalusi 45656b44f6 ASoC: omap-mcbsp: Create a single driver for McBSP
The OMAP McBSP driver stack used to contain two different
drivers. One of them was used as kind low-level access to
the IP, while the other driver was the ASoC DAI driver.
There were global, shared structures, in different places,
the McBSP instances are reffered with id numbers (sometimes
0 based, in other cases 1 based id numbers).

Create one single driver for OMAP McBSP with name: omap-mcbsp.
Convert the old omap-mcbsp driver initially to be a library
for the omap-mcbsp DAI driver. With this change we can get rid
of all global variables, structures.

Further cleanup is coming...

Kevin Hilman 3ec2decbb6 ARM: OMAP: omap_device: remove omap_device_parent
Currently all omap_devices are forced to have the dummy device
'omap_device_parent' as a parent.  This was used to distinguish
omap_devices from "normal" platform_devices in the OMAP PM core code.

Now that we implement the PM core using PM domains, this is no longer
needed, and is removed.

This also frees up omap_devices to have a more complex parent/child
relationships that model actual device relationships.

The only in-tree user of omap_device_parent was the OMAP PM layer to
handle lost-context count for omap_devices.  That is now converted to
use the presence of the omap_device_pm_domain instead.

To set sr ntarget values for all volt_domain,
volt_table is retrieved by doing a look_up of 'vdd_name'
field from omap_hwmod but voltage domain pointer does not
belong to omap_hwmod and is not used anywhere else.
As a part of voltage layer and SR Layer clean up volt
pointer is removed from omap_hwmod and added in dev
attributes of SR. The value of the field must match
the voltage domain names for the binding to be effective.

This functionality has already been implemented in the cx20442 codec
driver (commit f75a8ff67d, "ASoC: cx20442:
add bias control over a platform provided regulator"), no need to keep
it here duplicated.

Once done, remove the no longer used AMS_DELTA_LATCH2_MODEM_NRESET
symbol from the board header file and a call to the regulator_toggle()
helper function from the old API wrapper found in the board file.  While
being at it, simplify the way the modem .pm callback handles the
regulator and drop that helper function and its related consumer setup
completely.

Depends on patches 1/3 and 2/3 for clean apply and keep things working.

Cousson, Benoit 5a3ff8473c ARM: OMAP: irqs: Fix NR_IRQS value to handle PRCM interrupts
The following commit: 2f31b51659
Author: Tero Kristo <t-kristo@ti.com>
Date:   Fri Dec 16 14:37:00 2011 -0700

    ARM: OMAP4: PRM: use PRCM interrupt handler

introduced the PRCM interrupt handler and thus the need
for 64 more interrupts. Since SPARSE_IRQ is still not fully
functional on OMAP, the NR_IRQS needs to be updated to avoid
the failure that happen during irq_alloc_descs call inside
the PRCM driver:

[    0.208221] PRCM: failed to allocate irq descs: -12

Later the mux framework is then unable to request an IRQ from
the PRCM interrupt handler.

[    1.802795] mux: Failed to setup hwmod io irq -22

Fix that by adding 64 more interrupts for OMAP2PLUS config.

Tony Lindgren acea7c7b81 ARM: OMAP2+: Limit omap_read/write usage to legacy USB drivers
Drivers should no longer use omap_read/write functions
but instead use ioremap + read/write functions.

As some USB legacy code is still shared between omap1 and
omap2420, let's limit the omap_read/write to plat/usb.h.

Note that the long term fix is to update the drivers to
use ioremap and read/write functions. That can now be
done as a separate patch series that is limited to the
USB drivers.

Also make sure the legacy omap1-keypad.c driver builds
if selected for 2420 based systems.

In an effort to clean up the old omapfb driver, this patch removes
HWA742 (the display chip used in N770) platform data. This can be done
as N770 is the only user of HWA742, and the platform data contains only
one field, te_connected, which we can just presume to be true in the
HWA742 driver.

This allows us to remove omapfb_set_ctrl_platform_data(), and the
mechanism to pass the platform data, in a later patch.

Ohad Ben-Cohen 993e4fbd78 ARM: OMAP: omap_device: Expose omap_device_{alloc, delete, register}
Expose omap_device_{alloc, delete, register} so we can use them outside
of omap_device.c.

This approach allows users, which need to manipulate an archdata member
of a device before it is registered, to do so. This is also useful
for users who have their devices created very early so they can be used
at ->reserve() time to reserve CMA memory.

The immediate use case for this is to set the private iommu archdata
member, which binds a device to its associated iommu controller.
This way, generic code will be able to attach omap devices to their
iommus, without calling any omap-specific API.

With this in hand, we can further clean the existing mainline OMAP iommu
driver and its mainline users, and focus on generic IOMMU approaches
for future users (rpmsg/remoteproc and the upcoming generic DMA API).

This patch is still considered an interim solution until DT fully materializes
for omap; at that point, this functionality will be removed as DT will
take care of creating the devices and configuring them correctly.

Tested on OMAP4 with a generic rpmsg/remoteproc that doesn't use any
omap-specific IOMMU API anymore.

Ohad Ben-Cohen 34ed5a33b1 remoteproc/omap: add a remoteproc driver for OMAP4
Add a remoteproc driver for OMAP4, so we can boot the dual-M3 and
and DSP subsystems.

Use the omap_device_* API to control the hardware state, and utilize
the OMAP mailbox to interrupt the remote processor when a new message
is pending (the mailbox payload is used to tell it which virtqueue was
the message placed in).

Conversely, when an inbound mailbox message arrives, tell the remoteproc
core which virtqueue is triggered.

Later we will also use the mailbox payload to signal omap-specific
events like remote crashes (which will be used to trigger remoteproc
recovery) and power management transitions. At that point we will also
extend the remoteproc core to support this.

Based on (but now quite far from) work done by Fernando Guzman Lugo
<fernando.lugo@ti.com> and Hari Kanigeri <h-kanigeri2@ti.com>.

mpuio_init() function is defined under #ifdefs. It is required only in case
of MPUIO bank type and only when PM operations are supported by it.
This is applicable only in case of OMAP16xx SoC's MPUIO GPIO bank type.
For all the other cases it is a dummy function. Hence clean up the same
and remove all the OMAP SoC specific #ifdefs.

Charulatha V 0cde8d03dd gpio/omap: use flag to identify wakeup domain
In omap3, save/restore context is implemented for GPIO banks 2-6 as GPIO bank1
is in wakeup domain. Instead of identifying bank's power domain by bank id,
use 'loses_context' flag which is filled by pwrdm_can_ever_lose_context()
during dev_init.

For getting the powerdomain pointer, omap_hwmod_get_pwrdm() is used.
omap_device_get_pwrdm() could not be used as the pwrdm information needs to be
filled in pdata, whereas omap_device_get_pwrdm() could be used only after
omap_device_build() call.

Janusz Krzysztofik 8d09a1bb31 input: serio: ams-delta: toggle keyboard power over GPIO
Don't use Amstrad Delta custom I/O functions once GPIO interface is
available for the underlying hardware.

While requesting and initializing GPIO pins used, also take care of one
extra pin KEYBRD_DATAOUT which, even if not used by the driver, belongs
to the device and affects its functioning.

Once done, move the driver initialization back to the device_initcall
level, reverting the temporary chane introduced with patch 1/7 "ARM:
OMAP1: ams-delta: register latch dependent devices later".  That change
is no longer required once the driver takes care of registering used
GPIO pins, and it's better to initialize the device before others using
the latch2 based GPIO pins, otherwise a garbage is reported on boot,
perhaps due to random data already captured by the FIQ handler while the
keyboard related latch bits are written with random values during
initialization of those other latch2 dependent devices.

Janusz Krzysztofik 937eb4bb00 ARM: OMAP1: ams-delta: convert latches to basic_mmio_gpio
Once ready, ams-delta specific device drivers currently calling custom
ams_delta_latch[12]_write() functions can be updated to call generic
gpio_set_value() instead, which will make them less platform dependent.
Even more, some custom ams-delta only drivers can perhaps be dropped
from the tree after converting selected ams-delta platform devices to
follow generic GPIO based device models.

The latch_gpios[] table is initially filled with all latch1 and latch2
GPIO pins in order to register and initialize them from the board file
until those are handled by respective existing device drivers (leds,
nand, lcd, serio, asoc, serial). That table will get almost empty after
the transision process is completed, holding only pins not used by any
drivers / connected to unused devices, in order to initialize them from
the board file for power saving purposes.

The new ams_delta_latch_write() function is a unified replacement for
those removed ams_delta_latch[12]_write(), and serves as a temporary
wrapper over gpio_set_value(), providing the old API for those not yet
updated device drivers, and will be removed after all custom drivers are
converted or replaced.

Marc Zyngier 2f0778afac ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtime
sched_clock() is yet another blocker on the road to the single
image. This patch implements an idea by Russell King:

http://www.spinics.net/lists/linux-omap/msg49561.html

Instead of asking the platform to implement both sched_clock()
itself and the rollover callback, simply register a read()
function, and let the ARM code care about sched_clock() itself,
the conversion to ns and the rollover. sched_clock() uses
this read() function as an indirection to the platform code.
If the platform doesn't provide a read(), the code falls back
to the jiffy counter (just like the default sched_clock).

This allow some simplifications and possibly some footprint gain
when multiple platforms are compiled in. Among the drawbacks,
the removal of the *_fixed_sched_clock optimization which could
negatively impact some platforms (sa1100, tegra, versatile
and omap).

Tested on 11MPCore, OMAP4 and Tegra.

Rajendra Nayak aacf094128 ARM: OMAP2+: hwmod: Add a new flag to handle hwmods left enabled at init
An hwmod with a 'HWMOD_INIT_NO_IDLE' flag set, is left in
enabled state by the hwmod framework post the initial setup.
Once a real user of the device (a driver) tries to enable it
at a later point, the hwmod framework throws a WARN() about
the device being already in enabled state.

Fix this by introducing a new internal flag '_HWMOD_SKIP_ENABLE' to
identify such devices/hwmods. When the device/hwmod is requested to be
enabled (the first time) by its driver/user, nothing except the
mux-enable is needed. The mux data is board specific and is
unavailable during initial enable() of the device, done by the
framework as part of setup().

A good example of a such a device is an UART used as debug console.
The UART module needs to be kept enabled through the boot, until the
UART driver takes control of it, for debug prints to appear on
the console.

Govindraj.R 2fd149645e ARM: OMAP2+: UART: Remove omap_uart_can_sleep and add pm_qos
Omap_uart_can_sleep function blocks system wide low power state until
uart is active remove this func and add qos requests to prevent
MPU from transitioning.

Keep qos request to default value which will allow MPU to transition
and while uart baud rate is available calculate the latency value
from the baudrate and use the same to hold constraint while uart clocks
are enabled, and if uart is auto-idled the constraint is updated with
default constraint value allowing MPU to transition.

Qos requests are blocking notifier calls so put these requests to
work queue, also the driver uses irq_safe version of runtime API's
and callbacks can be called in interrupt disabled context.
So to avoid warn on slow path warning while using qos update
API's from runtime callbacks use the qos_work_queue.

During bootup the runtime_resume call backs might not be called and runtime
callback gets called only after uart is idled by setting the autosuspend
timeout. So qos_request from runtime resume callback might not activated during
boot if uart baudrate is calculated during bootup for console uart, so schedule
the qos_work queue once we calc_latency while configuring the uart port.

Flush and complete any pending qos jobs in work queue while suspending.

Jon Hunter a9e210e0b7 ARM: OMAP2+: UART: Make the RX_TIMEOUT for DMA configurable for each UART
When using DMA there are two timeouts defined. The first timeout,
rx_timeout, is really a polling rate in which software polls the
DMA status to see if the DMA has finished. This is necessary for
the RX side because we do not know how much data we will receive.
The secound timeout, RX_TIMEOUT, is a timeout after which the
DMA will be stopped if no more data is received. To make this
clearer, rename rx_timeout as rx_poll_rate and rename the
function serial_omap_rx_timeout() to serial_omap_rxdma_poll().

The OMAP-Serial driver defines an RX_TIMEOUT of 3 seconds that is
used to indicate when the DMA for UART can be stopped if no more
data is received. The value is a global definition that is applied
to all instances of the UART.

Each UART may be used for a different purpose and so the timeout
required may differ. Make this value configurable for each UART so
that this value can be optimised for power savings.

Deepak K c86845db77 ARM: OMAP2+: UART: Allow UART parameters to be configured from board file.
The following UART parameters are defined within the UART driver:

1). Whether the UART uses DMA (dma_enabled), by default set to 0
2). The size of dma buffer (set to 4096 bytes)
3). The time after which the dma should stop if no more data is received.
4). The auto suspend delay that will be passed for pm_runtime_autosuspend
    where uart will be disabled after timeout

Different UARTs may be used for different purpose such as the console,
for interfacing bluetooth chip, for interfacing to a modem chip, etc.
Therefore, it is necessary to be able to customize the above settings
for a given board on a per UART basis.

This change allows these parameters to be configured from the board file
and allows the parameters to be configured for each UART independently.

If a board does not define its own custom parameters for the UARTs, then
use the default parameters in the structure "omap_serial_default_info".
The default parameters are defined to be the same as the current settings
in the UART driver to avoid breaking the UART for any cuurnelty supported
boards. By default, make all boards use the default UART parameters.

Govindraj.R 62f3ec5fbd ARM: OMAP2+: UART: Add wakeup mechanism for omap-uarts
From the runtime callbacks enable hwmod wakeups for uart which will
internally enable io-pad wakeups for uarts if they have rx-pad pins
set as wakeup capabale.

Use the io-ring wakeup mechanism after uart clock gating and leave
the PM_WKST set for uart to default reset values cleanup the
code in serial.c which was handling PM_WKST reg.
Irq_chaing(PRM_DRIVER) is used to wakeup uart after uart clocks are gated
using pad wakeup mechanism.

Govindraj.R 273558b3a0 ARM: OMAP2+: UART: Cleanup part of clock gating mechanism for uart
Currently we use a shared irq handler to identify uart activity and then
trigger a timer. By default the timeout value is zero and can be set or
modified from sysfs. If there was no uart activity for the period set
through sysfs, the timer will expire and call timer handler this will
set a flag can_sleep using which decision to gate uart clocks can be taken.

Since the clock gating mechanism is outside the uart driver, we currently
use this mechanism. In preparation to runtime implementation for omap-serial
driver we can cleanup this mechanism and use runtime API's to gate uart clocks.

Removes the following:
* timer related info from local uart_state struct
* the code used to set timeout value from sysfs.
* irqflags used to set shared irq handler.
* un-used function omap_uart_check_wakeup.

This patch updates the common platform files with AM335X device
support (AM33XX family).

The approach taken in this patch is,
AM33XX device will be considered as OMAP3 variant, and a separate
SoC class created for AM33XX family of devices with a subclass type
for AM335X device, which is newly added device in the family.

This means, cpu_is_omap34xx(), cpu_is_am33xx() and cpu_is_am335x()
checks will return success on AM335X device.
A kernel config option CONFIG_SOC_OMAPAM33XX is added under OMAP3
to include support for AM33XX build.

Also, cpu_mask and RATE_IN_XXX flags have crossed 8 bit hence
struct clksel_rate.flags, struct prcm_config.flags and cpu_mask
are changed to u16 from u8.

For still better multi-OMAP1 support, expand omap1_rate_table with flags
for different SoC types and match them while selecting clock rates. The
idea is stolen from current omap24xx clock rate selection algorithm.

Since clkdev platform flag definitions are reused here, those had to be
expanded with one extra entry for OMAP1710 subtype, as this is the only
SoC for which we allow selection of the highest, 216 MHz rate.

Once done, remove no longer needed clock rate configure time options.

Santosh Shilimkar 137d105d50 ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.
On OMAP4 SOC, intecronnects has many write buffers in the async bridges
and they need to be drained before CPU enters into standby state.

Patch 'OMAP4: PM: Add CPUX OFF mode support' added CPU PM support
but OMAP errata i688 (Async Bridge Corruption) needs to be taken
care to avoid issues like system freeze, CPU deadlocks, random
crashes with register accesses, synchronisation loss on initiators
operating on both interconnect port simultaneously.

As per the errata, if a data is stalled inside asynchronous bridge
because of back pressure, it may be accepted multiple times, creating
pointer misalignment that will corrupt next transfers on that data
path until next reset of the system (No recovery procedure once
the issue is hit, the path remains consistently broken).
Async bridge can be found on path between MPU to EMIF and
MPU to L3 interconnect. This situation can happen only when the
idle is initiated by a Master Request Disconnection (which is
trigged by software when executing WFI on CPU).

The work-around for this errata needs all the initiators
connected through async bridge must ensure that data path
is properly drained before issuing WFI. This condition will be
met if one Strongly ordered access is performed to the
target right before executing the WFI. In MPU case, L3 T2ASYNC
FIFO and DDR T2ASYNC FIFO needs to be drained. IO barrier ensure
that there is no synchronisation loss on initiators operating
on both interconnect port simultaneously.

Thanks to Russell for a tip to conver assembly function to
C fuction there by reducing 40 odd lines of code from the patch.
