I believe the VMMC2 constraints must be the same than with VAUX3. Older
boards are using TWL4030 VMMC2 supply for internal MMC whereas newer are
using VAUX3 that has more limited constraints defined in this same file.
More over, the VMMC2 supply is used also for analog audio domain and the
miminum analog voltage of the TLV320AIC34 codec is 2.7 V.
To combine these two facts, the patch changes supply name to V28_A as the
newer boards register VMMC2_30 for VAUX3 and uses the same constraints than
VAUX3 since those constraints are ok for the TLV320AIC34.

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.

This fixes the commit 87aef30eb3

The Touch controller and LCD Panel share the same SPI bus 1.
So, we need to define the touch controller in the SPI board info
else, the SPI bus will be contended due to invalid state of
Touch controller's Chip Select thus preventing the LCD panel

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.

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.

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.

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.

PL330 is a configurable DMA controller PrimeCell device.
The register map of the device is well defined.
The configuration of a particular implementation can be
read from the six configuration registers CR0-4,Dn.
This patch implements a driver for the specification:-
http://infocenter.arm.com/help/topic/com.arm.doc.ddi0424a/DDI0424A_dmac_pl330_r0p0_trm.pdf
The exported interface should be sufficient to implement
a driver for any DMA API.

The L310 cache controller's interface is almost identical
to the L210. One major difference is that the PL310 can
have up to 16 ways.
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.

Convert code away from ->read_proc/->write_proc interfaces. Switch to
proc_create()/proc_create_data() which makes addition of proc entries
reliable wrt NULL ->proc_fops, NULL ->data and so on.
Problem with ->read_proc et al is described here commit
786d7e1612 "Fix rmmod/read/write races in
/proc entries"
This patch is part of an effort to remove the old simple procfs PAGE_SIZE
buffer interface.

DA8xx OHCI driver fails to load due to failing clk_get() call for the USB 2.0
clock. Arrange matching USB 2.0 clock by the clock name instead of the device.
(Adding another CLK() entry for "ohci.0" device won't do -- in the future I'll
also have to enable USB 2.0 clock to configure CPPI 4.1 module, in which case
I won't have any device at all.)
