New device support:
* adi,ad5766
- New driver supporting AD5766 and AD5767 16 channel DACs.
* adi,ad7476
- Support for LTC2314-14 14 bit ADC (trivial to add)
* hid-sensors-hinge

operation.

Currently, only the 112bit PROM with 7 words is supported. However the ms58xx
family also have devices with a 128bit PROM on 8 words. See AN520:
C-CODE EXAMPLE FOR MS56XX, MS57XX (EXCEPT ANALOG SENSOR), AND MS58XX SERIES
PRESSURE SENSORS and the various device datasheets.
The difference is that the CRC is the 4 LSBs of word7 instead of being the
4 MSBs of word0.

The CRC calculation always happens on 8 words which is why there is an
extra element in the prom array of struct ms_tp_dev. However, on ms5637 and
similar, only 7 words are readable.
Then, set MS_SENSORS_TP_PROM_WORDS_NB to 8 and stop passing a len parameter
to ms_sensors_tp_crc_valid as this simply hide the fact that it is
hardcoded.
Finally, use the newly introduced hw->prom_len to know how many words can be
read.

Some enums might have gaps or reserved values in the middle of their value
range. E.g. consider a 2-bit enum where the values 0, 1 and 3 have a
meaning, but 2 is a reserved value and can not be used.
Add support for such enums to the IIO enum helper functions. A reserved
values is marked by setting its entry in the items array to NULL rather
than the normal descriptive string value.

The Hinge sensor is a common custom sensor on laptops. It calculates
the angle between the lid (screen) and the base (keyboard). In addition,
it also exposes screen and the keyboard angles with respect to the
ground. Applications can easily get laptop's status in space through
this sensor, in order to display appropriate user interface.

Currently custom sensors properties are not decoded and it is up to
user space to interpret.
Some manufacturers already standardized the meaning of some custom sensors.
They can be presented as a proper IIO sensor. We can identify these sensors
based on manufacturer and serial number property in the report.
This change is identifying hinge sensor when the manufacturer is "INTEL".
This creates a platform device so that a sensor driver can be loaded to
process these sensors.

qcom_vadc7_scale_hw_calib_die_temp() uses a table format different from
the rest of volt/temp conversion functions in this file. Also the
conversion functions results in non-monothonic values conversion, which
seems wrong.
Rewrite qcom_vadc7_scale_hw_calib_die_temp() to use
qcom_vadc_map_voltage_temp() directly, like the rest of conversion
functions do.

"This is two driver fixes (megaraid_sas and hisi_sas).
The megaraid one is a revert of a previous revert of a cpu hotplug fix
which exposed a bug in the block layer which has been fixed in this
merge window.
The hisi_sas performance enhancement comes from switching to interrupt
managed completion queues, which depended on the addition of
devm_platform_get_irqs_affinity() which is now upstream via the irq
tree in the last merge window"
