Most applications are too noisy to allow the default noise and
watchdog settings, and thus need to be configurable via DT
properties.
Also default settings to POR defaults on a reset, and register
distuber interrupts as noise since it prevents proper usage.

Round one of new device support, features and cleanup for IIO in the 4.15 cycle.
Note there is a misc driver drop in here given we have support
in IIO and the feeling is no one will care.
A large part of this series is a boiler plate removal series avoiding
the need to explicitly provide THIS_MODULE in various locations.
It's very dull but touches all drivers.
New device support
* ad5446
- add ids to support compatible parts DAC081S101, DAC101S101,
DAC121S101.
- add the dac7512 id and drop the misc driver as feeling is no
one is using it (was introduced for a board that is long obsolete)
* mt6577
- add bindings for mt2712 which is fully compatible with other
supported parts.
* st_pressure
- add support for LPS33HW and LPS35HW with bindings (ids mostly).
New features
* ccs811
- Add support for the data ready trigger.
* mma8452
- remove artifical restriction on supporting multiple event types
at the same time.
* tcs3472
- support out of threshold events
Core and tree wide cleanup
* Use macro magic to remove the need to provide THIS_MODULE as part of
struct iio_info or struct iio_trigger_ops. This is similar to
work done in a number of other subsystems (e.g. i2c, spi).
All drivers are fixed and then the fields in these structures are
removed.
This will cause build failures for out of tree drivers and any
new drivers that cross with this work going into the kernel.
Note mostly done with a coccinelle patch, included in the series
on the mailing list but not merged as the fields no longer exist
in the structures so the any hold outs will cause a build failure.
Cleanups
* ads1015
- avoid writing config register when it doesn't change.
- add 10% to conversion wait time as it seems it is sometimes
a little small.
* ade7753
- replace use of core mlock with a local lock. This is part of a
long term effort to make the use of mlock opaque and single
purpose.
* ade7759
- expand the use of buf_lock to cover previous mlock cases. This
is a slightly nicer solution to the same issue as in ade7753.
* cros_ec
- drop an unused variable
* inv_mpu6050
- add a missing break in a switch for consistency - not actual
bug,
- make some local arrays static to save on object code size.
* max5481
- drop manual setting of the spi module owner as handled by the
spi core.
* max5487
- drop manual setting of the spi module owner as handled by the
spi core.
* max9611
- drop explicit setting of the i2c module owner as handled by
the i2c core.
* mcp320x
- speed up reads on single channel devices,
- drop unused of_device_id data elements,
- document the struct mcp320x,
- improve binding docs to reflect restrictions on spi setup and
to make it explicit that the reference regulator is needed.
* mma8452
- symbolic to octal permissions,
- unsigned to unsigned int.
* st_lsm6dsx
- avoid setting odr values multiple times,
- drop config of LIR as it is only ever set to the existing
defaults,
- drop rounding configuration as it only ever matches the defaults.
* ti-ads8688
- drop manual setting of the spi module owner as handled by the
spi core.
* tsl2x7x
- constify the i2c_device_id,
- cleanup limit checks to avoid static checker warnings (and generally
have nicer code).

All chips supported by this driver clock data out on the falling edge
and latch data in on the rising edge, hence SPI mode (0,0) or (1,1)
must be used.
Furthermore, none of the chips has an internal reference voltage
regulator, so an external supply is always required and needs to be
specified in the device tree lest the IIO "scale" in sysfs cannot be
calculated.
Document these requirements in the device tree binding, add compatible
strings for the newly supported mcp3550/1/3 and explain that SPI mode
(0,0) should be preferred for these chips.

Use integers (reg property) to tell the number of the LED to the driver
instead of the node name. While both of these approaches are currently
used by the LED bindings, using integers will require less driver changes
for ACPI support. Additionally, it will make possible LED naming using
chip and LED node names, effectively making the label property most useful
for human-readable names only.

This example allocates much more than needed for address regions.
As for "denali_reg", as you see in drivers/mtd/nand/denali.h, all
registers fit in 0x1000.
As for "nand_data", this IP is generally configured to use Indexed
Addressing mode, where there are only two registers in the address
translation module (CTRL: 0x00, DATA: 0x10). Altera SOCFPGA is
also this case. So, 0x20 is enough.

On newer imx SOCs accessing OCOTP directly is wrong because the ocotp
clock needs to be enabled first. Add a binding for accessing the same
values through the imx-ocotp nvmem driver using nvmem-cells. This is
similar to other thermal drivers.
The old binding is preserved for compatibility and because it still
works fine on imx6qdl series chips.
In theory this problem could be solved by adding a reference to the
OCOTP clock instead but it is better to hide such details in a specific
nvmem driver.
