Kalle Jokiniemi 20c9d2c4ab i2c-omap: add mpu wake up latency constraint in i2c
While waiting for completion of the i2c transfer, the
MPU could hit OFF mode and cause several msecs of
delay that made i2c transfers fail more often. The
extra delays and subsequent re-trys cause i2c clocks
to be active more often. This has also an negative
effect on power consumption.

Created a mechanism for passing and using the
constraint setting function in driver code. The used
mpu wake up latency constraints are now set individually
per bus, and they are calculated based on clock rate
and fifo size.

Thanks to Jarkko Nikula, Moiz Sonasath, Paul Walmsley,
and Nishanth Menon for tuning out the details of
this patch.

Updates by Kevin as requested by Tony:

- Remove omap_set_i2c_constraint_func() in favor of conditionally
  adding the flag in omap_i2c_add_bus() in order to keep all the OMAP
  conditional checking in a single location.
- Update set_mpu_wkup_lat prototypes to match OMAP PM layer so
  OMAP PM function can be used directly in pdata.

Marek Szyprowski 1131379b48 ARM: SAMSUNGy: fix broken timer irq base
Timer interrupts range was defined as 43-47, what overlaps with VIC0 range
(32-64). This was caused probably by a typo while the common interrupts
definition was refactored. This patch moves timer interrupt range to safe
area of 11-15 (just before uart range).

This fixes the commit 87aef30eb3
("ARM: S5P: Change S5P_TIMER_IRQ based to 11 for SAMSUNG S5P series.")
which meant to move these into the old (and previously reserved)
ISA space.

Jassi Brar d800edebe3 S3C: DMA: Add api driver for PL330
Latest Samsung SoCs have one or more PL330 as their DMACs. This patch
implements the S3C DMA API for PL330 core driver.

The design has been kept as generic as possible while keeping effort to
add support for new SoCs to the minimum possible level.

Some of the salient features of this driver are:-
 o  Automatic scheduling of client requests onto DMAC if more than
    one DMAC can reach the peripheral. Factors, such as current load
    and number of exclusive but inactive peripherals that are
    supported by the DMAC, are used to decide suitability of a DMAC
    for a particular client.
 o  CIRCULAR buffer option is supported.
 o  The driver scales transparently with the number of DMACs and total
    peripherals in the platform, since all peripherals are added to
    the peripheral pool and DMACs to the controller pool.

For most conservative use of memory, smallest driver size and best
performance, we don't employ legacy data structures of the S3C DMA API.
That should not have any affect since those data structures are completely
invisible to the DMA clients.

Wolfgang Grandegger 56e6943b90 can: sja1000 platform data fixes
The member "clock" of struct "sja1000_platform_data" is documented as
"CAN bus oscillator frequency in Hz" but it's actually used as the CAN
clock frequency, which is half of it. To avoid further confusion, this
patch fixes it by renaming the member to "osc_freq". That way, also
non mainline users will notice the change. The platform code for the
relevant boards is updated accordingly. Furthermore, pre-defined
values are now used for the members "ocr" and "cdr".

Will Deacon 8c1fc96f6f ARM: 6072/1: oprofile: use perf-events framework as backend
There are currently two hardware performance monitoring subsystems in
the kernel for ARM: OProfile and perf-events. This creates the
following problems:

1.) Duplicate PMU accessor code. Inevitable code drift may lead to
bugs in one framework that are fixed in the other.

2.) Locking issues. OProfile doesn't reprogram hardware counters
between profiling runs if the events to be monitored have not been
changed. This means that other profiling frameworks cannot use the
counters if OProfile is in use.

3.) Due to differences in the two frameworks, it may not be possible to
compare the results obtained by OProfile with those obtained by perf.

This patch removes the OProfile PMU driver code and replaces it with
calls to perf, therefore solving the issues mentioned above.

The only userspace-visible change is the lack of SCU counter support
for 11MPCore. This is currently unsupported by OProfile userspace tools anyway and therefore shouldn't cause any problems.

Will Deacon 181193f398 ARM: 6069/1: perf-events: use numeric ID to identify PMU
The ARM perf-events framework provides support for a number of different
PMUs using struct arm_pmu. The char *name field of this struct can be
used to identify the PMU, but this is cumbersome if used outside of perf.

This patch replaces the name string for a PMU with an enum, which holds
a unique ID for the PMU being represented. This ID can be used to index
an array of names within perf, so no functionality is lost. The presence
of the ID field, allows other kernel subsystems [currently oprofile] to
use their own mappings for the PMU name.

Will Deacon 49c006b937 ARM: 6064/1: pmu: register IRQs at runtime
The current PMU infrastructure for ARM requires that the IRQs for the PMU
device are fixed at compile time and are selected based on the ARCH_ or MACH_ flags. This has the disadvantage of tying the Kernel down to a
particular board as far as profiling is concerned.

This patch replaces the compile-time IRQ registration with a runtime mechanism which allows the IRQs to be registered with the framework as
a platform_device.

A further advantage of this change is that there is scope for registering
different types of performance counters in the future by changing the id
of the platform_device and attaching different resources to it.

Thomas Abraham c62ec6a9aa ARM: S5PV210: Rearrange assignment of clock for fout apll/mpll/epll clocks
The assignment of clock rates for fout apll/mpll/epll is moved further
up in the s5pv210_setup_clocks function because the subsequent patches
require the clock rate of fout clocks to be setup.

Thomas Abraham eb1ef1ed06 ARM: S5PV210: Register apll/mpll/epll clksrc_clk clocks
This patch modifies the following.

1. Registers the mout_apll clksrc_clk clock.

2. The mout_mpll and mout_epll clocks were registered as 'struct clk'
   types and then their parents were setup using the s3c_set_clksrc
   function. This patch reduces the two steps into one by registering
   the mout_mpll and mout_epll clocks using the s3c_register_clksrc
   function.

3. As per point 2 above, the init_parents array is no longer required.
   So the mout clocks are now put together in a new array named 'sysclks'.
   The sysclks array will list the system level clocks and more
   clocks will be added to it in the subsequent patches.

4. The clks array is left empty because of the movement of mpll and epll
   clocks into the sysclks array. It is not deleted since subsequent
   patches will add clocks into this array.

The system clock definitions are currently defined below the
peripheral clock definitions in the V210 clock code. For the V210
clock updates that follow this patch, it is required that the
system clock definitions such as the mout_apll and mout_mpll be
defined prior to the device clock definitions. This patch
re-arranges the system clock defintions for the clock updates that
follow this patch.

Kirill A. Shutemov 8c0b742ca7 ARM: 6134/1: Handle instruction cache maintenance fault properly
Between "clean D line..." and "invalidate I line" operations in
v7_coherent_user_range(), the memory page may get swapped out.
And the fault on "invalidate I line" could not be properly handled
causing the oops.

In ARMv6 "external abort on linefetch" replaced by "instruction cache
maintenance fault". Let's handle it as translation fault. It fixes the
issue.

I'm not sure if it's reasonable to check arch version in run-time.
Let's do it in compile time for now.

This patch implements a driver for the specification:-

The L310 cache controller's interface is almost identical
to the L210. One major difference is that the PL310 can

This change uses the cache's part ID and the Associativity
bits in the AUX_CTRL register to determine the number of ways.

Also, this version prints out the CACHE_ID and AUX_CTRL registers.

Cyril Chemparathy bcd6a1c695 Davinci: iotable based ioremap() interception
This patch allows for a more flexible ioremap() interception based on iotable
contents.

With this patch, the ioremap() interception code can properly translate
addresses only after davinci_soc_info has been initialized.  Consequently,
in soc-specific init functions, davinci_common_init() has to happen before any
ioremap() attempts. The da8xx init sequence has been suitably modified to meet
this restriction.

The previous dependency did not handle all corner cases. Since there
was no sleep dependency between CORE and PER domains, if PER enters
RET and CORE is ON, PER will not be active for GPIO handling.

Mike Chan 40742fa82e OMAP3: PM: Enable IO / IO-CHAIN wakeups for PER
IO events can also come from GPIO modules, which reside in the PER domain.
It is possible for the PER to enter RET while CORE is still in ON.
If GPIO 2-6 are enabled for IO-pad wakeups, the PER domain will not
wakeup in this case, unless we enable it.

Ranjith Lohithakshan 7a44ad2fce OMAP3: PM: Enable wakeup from ads7846 touchscreen
This  patch enables the wakeup capabilities of ads7846 touchscreen driver.
ads7846 driver can now wakeup the system from suspend on OMAP3430 EVM
and SDP boards.

The earlier approach of enabling wakeup on the touchscreen GPIO pin during
board level mux init is removed. Instead the wakeup flag in
ads7846_platform_data is enabled. Based on the flag, the ads7846 driver
will do an enable_irq_wake which will eventually call into the OMAP GPIO
layer and will enable the wakeup capability on the GPIO pin.

Ranjith Lohithakshan f3a8cde6bc OMAP3EVM: Update pad configuration for wakeup enabled pads
OMAP3530 TRM section 7.4.4.4.2 requires OFFOUTENABLE to be set (active low)
if wakeup capabilities are enabled on a pad. During OFF mode testing
on OMAP3530 EVM, it was observed that the device was not residing in
the OFF state. The device enters into the OFF state and immediately exits
from that state as if an IO wakeup event has occured. The issue was traced
down to the pad configuration of wkaeup enabled pad's.

Millisecond resolution is possible and there are use cases for it
(automatic testing).

Seconds-based interface is preserved for compatibility.

Kevin Hilman d6290a3ead OMAP3: PRCM interrupt: only check and clear enabled PRCM IRQs
While handling PRCM IRQs, mask out interrupts that are not enabled in
PRM_IRQENABLE_MPU.  If these are not masked out, non-enabled
interrupts are caught, a WARN() is printed due to no 'handler' and the
events are cleared.  In addition to being noisy, this can also
interfere with independent polling of this register by SR/VP code.

This was noticed using SmartReflex transitions which cause the VPx_*
interrupts to be handled since they are set in PRM_IRQSTATUS_MPU even
but not enabled in PRM_IRQENABLE_MPU.

When booting up we need to wait for the modem processor to
