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.

This adds an IIO magnetometer driver for the Yamaha
YAS530 family of magnetometer/compass chips YAS530,
YAS532 and YAS533.
A quick survey of the source code released by different
vendors reveal that we have these variants in the family
with some deployments listed:
* YAS529 MS-3C (2005 Samsung Aries)
* YAS530 MS-3E (2011 Samsung Galaxy S Advance)
* YAS532 MS-3R (2011 Samsung Galaxy S4)
* YAS533 MS-3F (Vivo 1633, 1707, V3, Y21L)
* (YAS534 is a magnetic switch)
* YAS535 MS-6C
* YAS536 MS-3W
* YAS537 MS-3T (2015 Samsung Galaxy S6, Note 5)
* YAS539 MS-3S (2018 Samsung Galaxy A7 SM-A750FN)
The YAS529 is so significantly different from the
YAS53x variants that it will require its own driver.
The YAS537 and YAS539 have slightly different register
sets but have strong similarities so a common driver
patching this one will probably be reasonable.
The source code for Samsung Galaxy A7's YAS539 is not
that is significantly different from the YAS530 in the
Galaxy S Advance, so I believe we will only need this
one driver with quirks to handle all of them.
The YAS539 is actively announced on Yamaha's devices
site:
https://device.yamaha.com/en/lsi/products/e_compass/
This is a driver written from scratch using buffered
IIO and runtime PM handling regulators and reset.
Thanks to Andy Shevchenko for great help in finding all
the special kernel infrastructure functions and quirks
during review of this driver.

The iio-core extends the attr_group provided by the driver with its
own attributes. To be able to do this it:
1. Has its own (non const) io_dev_opaque.chan_attr_group attr_group struct
2. It allocates a new attrs array with room for both the drivers and its
own attributes
3. It copies over the driver provided attributes into the newly allocated
attrs array.
But the drivers attr_group may contain more then just the attrs array, it
may also contain an is_visible callback and at least the adi-axi-adc.c
is currently defining such a callback.
Change the attr_group copying code to also copy over the is_visible
callback, so that drivers can define one and have it workins as is
normal for attr_group-s all over the kernel.
Note that the is_visible callback takes an index into the array as
argument, so that indices of the driver's attributes must not change,
this is not a problem as the driver's own attributes are added first
to the newly allocated attrs array and the attributes handled by the
core are appended after the driver's attributes.
