Jonathan writes:
First round of new IIO device support, features and cleanups for the 4.6 cycle.
Device Support
* ad5761
- new driver
* at91_sama5d2 ADC.
- new driver and MAINTAINERS entry.
- minor cleanups followed.
* atlas pH-SM
- new driver (this has possibly the prettiest data sheet I've ever seen)
* mcp3422
- mcp3425 ADC added.
* mcp4725
- mcp4726 DAC added.
* mma8452
- mma8451q accelerometer added.
* mpl115
- mpl115a1 added (a lot bigger than it seems as this is an SPI part whereas
previous parts were i2c).
* si7005
- Hoperf th02 (seems to be a repackaged part)
* si7020
- Hoperf th06 (seems to be a repackaged part)
New features
* Core
- IIO_PH type. Does what it says on the tin.
* max30100
- LED current configuration support.
* mcp320x
- more differential measurement combinations.
* mma8452
- free fall deteciton
- opt3001
- enable operation without a IRQ line.
- device tree docs. Somehow the original docs have disappeared down
a rabbit hole, so here is a new set.
* st-sensors
- Support active-low interrupts.
Cleanups and minor / not so minor reworks
* Documentation
- drop some defunct ABI from the docs in staging.
* presure / Kconfig
- white space cleanup.
* ad7150
- BIT macro usage
- Alignment fixes
* ad7192
- false indent fixed.
* ak8975
- constify the ak_def structures
* axp288
- drop a redundant double const.
* dht11
- substantial reliability improvements by being more tolerant
of missing start bits.
- simplify the decoding algorithm
* mma8452
- whitespace cleanup
* mpl115
- don't bother setting i2c_client_data as nothing uses it.
* mpu6050
- drop unused function parameter.
* opt3001
- extract integration time as constants.
- trivial refactoring.

The new algorithm uses a 'one size fits em all' threshold, which should
be easier to understand and debug. I believe there are no regressions
compared to the old adaptive threshold algorithm. I don't remember why
I chose the old algorithm when I initially wrote the driver.

Instead of guessing where the data starts, we now just try to decode from
every possible start position. This causes no additional overhead if we
properly received the full preamble and only costs a few extra CPU cycles
in the case where the preamble is corrupted. This is much more efficient
than to return an error to userspace and start over again.

mpl115 driver currently supports i2c interface (MPL115A2).
There is also SPI version (MPL115A1). The difference between them
is only physical transport so we can easily support both while sharing
most of the code.
Split the driver into a core support module and one module each for I2C
and SPI support.

Enable operation of the TI OPT3001 light sensor without having an
interrupt line available to connect the INT pin to.
In this operation mode, we issue a conversion request and simply wait
for the conversion time available as timeout value, determined from
integration time configuration and the worst-case time given in the data
sheet (sect. 6.5, table on p. 5):
short integration time (100ms): 110ms + 3ms = 113ms
long integration time (800ms): 880ms + 3ms = 883ms
This change is transparent as behaviour defaults to using the interrupt
method if an interrupt no. is configured via device tree. Interrupt-less
operation mode is performed when no valid interrupt no. is given.

Pull power management and ACPI fixes from Rafael Wysocki:
"These are: cpuidle fixes (including one fix for a recent regression),
cpufreq fixes (including fixes for two issues introduced during the
4.2 cycle), generic power domains framework fixes (two locking fixes
and one cleanup), one locking fix in the ACPI-based PCI hotplug
framework (ACPIPHP), removal of one ACPI backlight blacklist entry
that isn't necessary any more and a PM Kconfig cleanup.
Specifics:
- Fix a recent cpuidle core regression that broke suspend-to-idle on
all systems where cpuidle drivers don't provide ->enter_freeze
callbacks for any states (Sudeep Holla).
- Drop an unnecessary symbol definition from the cpuidle core code
handling coupled CPU cores (Anders Roxell).
- Fix a race condition related to governor initialization and removal
in the cpufreq core (Viresh Kumar).
- Clean up the cpufreq core to use list_is_last() for checking if the
given policy object is the last element of a list instead of open
coding that in a clumsy way (Gautham R Shenoy).
- Fix compiler warnings in the pxa2xx and cpufreq-dt cpufreq drivers
(Arnd Bergmann).
- Fix two locking issues and clean up a comment in the generic power
domains framework (Ulf Hansson, Marek Szyprowski, Moritz Fischer).
- Fix the error code path of one function in the ACPI-based PCI
hotplug framework (ACPIPHP) that forgets to release a lock acquired
previously (Insu Yun).
- Drop the ACPI backlight blacklist entry for Dell Inspiron 5737 that
is not necessary any more (Hans de Goede).
- Clean up the top-level PM Kconfig to stop requiring APM emulation
to depend on PM which in fact isn't necessary (Arnd Bergmann)"

The I2C bus names are supposed to be stable as they can be used by
userspace to uniquely identify a specific I2C bus. So restore the
original names for all legacy (pre-SB800) devices.
For SB800 devices and later, improve the names. "SDA" refers to the
serial data pin of each SMBus port, it's an implementation detail the
user doesn't need to know. Use "port" instead, which is easier to
understand.

Remove support for dgap driver since there is no way to get
the firmware files required by the dgap driver into the linux-
firmware tree. The dgap driver is rendered useless without this
firmware and hence this product is considered obsolete by DIGI.

Previously, speakup would always read the non-scrolled part of the VT,
even when the VT is scrolled back with shift-page. This patch makes
vt.c export screen_pos so that speakup can use it to properly access
the content of the scrolled-back VT.
This was tested with both vgacon and fbcon.

Commit f79b0d9c223c ("staging: speakup: Fixed warning <linux/serial.h>
instead of <asm/serial.h>") broke the port information in the speakup
driver: SERIAL_PORT_DFNS only gets defined if asm/serial.h is included,
and no other header includes asm/serial.h.
We here make sure serialio.c does get the arch-specific definition of
SERIAL_PORT_DFNS from asm/serial.h, if any.
Along the way, this makes sure that we do have information for the
requested serial port number (index)

This patch does the following:
* changed the complicated if statements to simple case statements
* in case of E_DEFAULT, no need to return error as ERESTART,
because this is the user asked for. Hence function should return success.
* ret variable is 0 always, hence removed it.
* removed one ternary operator, as it was always returning the status value only,
and hence removed the status variable too
