ee66e653ca mfd: Unify abx500 headers in mfd/abx500
This moves all the header files related to the abx500 family into
a common include directory below mfd. From now on we place any
subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface
remains in <linux/mfd/abx500.h>.

b18d1f0f49 mfd: Set twl4030-irq tertiary interrupts to be nested/threaded.
As tertiary interrupts are handled by handle_twl4030_sih calling

In ancient times it was necessary to manually initialize the bus field of an

so we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:

5bdf7411bc mfd: Fix 88pm860x test bank i2c interface bug
There are two banks in 88pm8607. One is the normal bank, and the other
one is the test bank, it means it have the same register address in the
normal bank and test bank seperately.
For test bank register, it needs a special I2C sequence to acess as below,
    Touching to 0xFA address
    Touching to 0xFB address
    Touching to 0xFF address
    Accessing bank register
    Touching to 0xFE address
    Touching to 0xFC address
This sequence can't be interrupted. It means that we can't use
i2c_transfef() to implement touching 0xFA address. Otherwise, other i2c
operation may be inserted into 0xFA and 0xFB operation since the lock of
i2c_adapter is already released.
So for test bank we implemented specific i2c read/write operation;

c1e61bcf82 mfd: Use request_threaded_irq for twl4030-irq instead of irq_set_chained_handler
irq_set_chained_handler sets 'desc->handle_irq'.
However this irq is called by handle_nested_irq from handle_twl4030_pih,
and that uses action->thread_fn.

So the handled set with irq_set_chained_handler is never called.

So change to use request_threaded_irq instead - that sets the correct field.

af65e6cef4 mfd: Set da903x bits if new value is different from the old one
It does not make sense to write new value only when all the bit_mask

We need to write new value if the bit mask fields of new value is

1e7fe1a925 MFD: OMAP: USB: Runtime PM support
The usbhs core driver does not enable/disable the interface and
functional clocks directly, These clocks are handled by runtime pm,
hence instead of the clock enable/disable, the runtime pm APIS are
used. however,the optional clocks and port clocks are handled by
the usbhs core.

Dependency:
This patch is dependent on this series:
[PATCH 0/5 v13 or latest version] omap: usb: host: Runtime PM preparation
for EHCI and OHCI drivers.

Validation performed:
The global suspend/resume of EHCI and OHCI is validated on
OMAP3430 sdp board with this patch combined with the series:

Describe the register map to the regmap core so that we can use its
diagnostic features and cache support.  This is split out from the patch
using it due to the size so that the actual code change is a bit clearer.

As the various devices are supersets of each other the access maps are
built up by layering the functions on top of each other, though the
interface for specifying the register defaults isn't currently amenable
to this.

3a7cbd50f7 freezer: don't unnecessarily set PF_NOFREEZE explicitly
Some drivers set PF_NOFREEZE in their kthread functions which is
completely unnecessary and racy - some part of freezer code doesn't
consider cases where PF_NOFREEZE is set asynchronous to freezer
operations.

In general, there's no reason to allow setting PF_NOFREEZE explicitly.
Remove them and change the documentation to note that setting
PF_NOFREEZE directly isn't allowed.

-v2: Dropped change to twl4030-irq.c as it no longer uses PF_NOFREEZE.

57265bc114 mfd: Convert db8500-prcmu panic() into pr_crit()
panic() is too heavy for this, indeed the PRCMU is critical for
the system but not to the point that we should stop everything,
if we can still get a prompt or so.

parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will
be diverted to respective driver. Common registers are in

782baa20b2 mfd: Disable twl6030 IRQ during suspend
Module IRQs may still be disabled by DPM at the time the TWL6030
ISR runs, causing handle_simple_irq() to silently do nothing.
This may result in missing TWL RTC alarm wakeups, for example,
since the RTC child module ISR is not called to ack the IRQ.

Disable the TWL6030 IRQ during suspend, enable it at DPM resume
time, at which time the child module IRQs will be re-enabled.

ab2b9260df mfd: Fix twl6030 lockdep recursion warning on setting wake IRQs
LOCKDEP explicitly sets all irq_desc locks as a single lock-class,
causing "possible recursive locking detected" when the TWL RTC
driver calls through enable_irq_wake to twl6030_irq_set_wake,
which recursively calls irq_set_irq_wake.  Although the
irq_desc and lock are different, LOCKDEP treats these as
equivalent, presumably due to problems that can be incurred
when locking more than one irq_desc, so best to avoid this.

Suspend/resume actions implemented as PM notifiers to avoid
touch the TWL core for this.

The AB3550 never passed the prototype stage. Instead it was used
as a precursor to AB5500 for testing basic building blocks used
in that chip, since they had large similarities. Since AB3550 will
not see the light of day in product form and since the prototypes
are no longer used, let's delete the driver and any references to
it.

The analog baseband chip ab5500 is a multi functional chip

It also contain various multimedia functionalities like digital
encoder and audio codec.
The core driver added with this patch provides register access via
i2c via PRCMU. Event handling implemented as irq_chip will come in
future patches since it depends on PRCMU functionality not yet
implemented.
