3ac27afefd iio:dac:ad5755: Switch to generic firmware properties and drop pdata
Lars pointed out that platform data can also be supported via the
generic properties interface, so there is no point in continuing to
support it separately.  Hence squish the linux/platform_data/ad5755.h
header into the c file and drop accessing the platform data directly.

Done by inspection only.  Mostly completely mechanical with the
exception of a few places where default value handling is
cleaner done by first setting the value, then calling the
firmware reading function but and not checking the return value,
as opposed to reading firmware then setting the default if an error
occurs.

Part of general attempt to move all of IIO over to generic
device properties, both to enable other firmware types and
to remove drivers that can be the source of of_ specific
behaviour in new drivers.

9020ef6598 iio: trigger: Fix a scheduling whilst atomic issue seen on tsc2046
IIO triggers are software IRQ chips that split an incoming IRQ into
separate IRQs routed to all devices using the trigger.
When all consumers are done then a trigger callback reenable() is
called.  There are a few circumstances under which this can happen
in atomic context.

1) A single user of the trigger that calls the iio_trigger_done()
function from interrupt context.
2) A race between disconnecting the last device from a trigger and
the trigger itself sucessfully being disabled.

To avoid a resulting scheduling whilst atomic, close this second corner
by using schedule_work() to ensure the reenable is not done in atomic
context.

Note that drivers must be careful to manage the interaction of
set_state() and reenable() callbacks to ensure appropriate reference
counting if they are relying on the same hardware controls.

Deliberately taking this the slow path rather than via a fixes tree
because the error has hard to hit and I would like it to soak for a while
before hitting a release kernel.

fea251b6a5 iio: addac: add AD74413R driver
The AD74412R and AD74413R are quad-channel, software configurable,
input/output solutions for building and process control applications.

They contain functionality for analog output, analog input, digital input,
resistance temperature detector, and thermocouple measurements integrated
into a single chip solution with an SPI interface.

The devices feature a 16-bit ADC and four configurable 13-bit DACs to
provide four configurable input/output channels and a suite of diagnostic
functions.

The AD74413R differentiates itself from the AD74412R by being
HART-compatible.

When configured with channel 0 as voltage output, channel 1 as current
output, channel 2 as voltage input and channel 3 as current input, the
following structure is created under the corresponding IIO device.

Pull percpu fixes from Dennis Zhou:
 "This contains a fix for SMP && !MMU archs for percpu which has been
  tested by arm and sh. It seems in the past they have gotten away with
  it due to mapping of vm functions to km functions, but this fell apart
  a few releases ago and was just reported recently.

  The other is just a minor dependency clean up.

  I think queued up right now by Andrew is a fix in percpu that papers
  of what seems to be a bug in hotplug for a special situation with
  memoryless nodes. Michal Hocko is digging into it further"

a882cc9497 perf intel-pt: Fix missing 'instruction' events with 'q' option
FUP packets contain IP information, which makes them also an 'instruction'
event in 'hop' mode i.e. the itrace 'q' option.  That wasn't happening, so
restructure the logic so that FUP events are added along with appropriate

c79ee2b216 perf intel-pt: Fix state setting when receiving overflow (OVF) packet
An overflow (OVF packet) is treated as an error because it represents a
loss of trace data, but there is no loss of synchronization, so the packet
state should be INTEL_PT_STATE_IN_SYNC not INTEL_PT_STATE_ERR_RESYNC.

To support that, some additional variables must be reset, and the FUP
packet that may follow OVF is treated as an FUP event.

ad106a26ae perf intel-pt: Fix sync state when a PSB (synchronization) packet is found
When syncing, it may be that branch packet generation is not enabled at
that point, in which case there will not immediately be a control-flow
packet, so some packets before a control flow packet turns up, get
ignored.  However, the decoder is in sync as soon as a PSB is found, so
the state should be set accordingly.
