389fc70b60 iio: temperature: mlx90632 Relax the compatibility check
Register EE_VERSION contains mixture of calibration information and DSP
version. So far, because calibrations were definite, the driver
compatibility depended on whole contents, but in the newer production
process the calibration part changes. Because of that, value in EE_VERSION
will be changed and to avoid that calibration value is same as DSP version
the MSB in calibration part was fixed to 1.
That means existing calibrations (medical and consumer) will now have
hex values (bits 8 to 15) of 83 and 84 respectively. Driver compatibility
should be based only on DSP version part of the EE_VERSION (bits 0 to 7)
register.

regmap: split up regmap_config.use_single_rw
Split regmap_config.use_single_rw into use_single_read and
use_single_write. This change enables drivers of devices which only
support bulk operations in one direction to use the regmap_bulk_*()
functions for both directions and have their bulk operation split into
single operations only when necessary.

Update all struct regmap_config instances where use_single_rw==true to
instead set both use_single_read and use_single_write. No attempt was
made to evaluate whether it is possible to set only one of
use_single_read or use_single_write.

c50fadeff7 iio temperature/mlx90632: silence a static checker warning
This shouldn't affect runtime at all, but Smatch complains that we
should check if mlx90632_read_ambient_raw() otherwise we
"ambient_new_raw" can be uninitialized.

    drivers/iio/temperature/mlx90632.c:509 mlx90632_calc_ambient_dsp105()
    error: uninitialized symbol 'ambient_new_raw'.

c87742abfc iio: temperature: Adding support for MLX90632
Melexis has just released Infra Red temperature sensor MLX90632 used
for contact-less temperature measurement. Driver provides basic
functionality for reporting object (and ambient) temperature with
support for object emissivity.
