9ea7c79097 iio:common:ms_sensors:ms_sensors_i2c: add support for alternative PROM layout
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.

7ae7f75080 iio:common:ms_sensors:ms_sensors_i2c: rework CRC calculation helper
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.

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.

688daed2e5 SCSI fixes on 20210110
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 and 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.
