Historically the tsens driver fetches the calibration data as a blob and
then parses the blob on its own. This results in semi-duplicated code
spreading over the platform-specific functions.
This patch series changes tsens calibration code to use pre-parsed nvmem
cells rather than parsing the blob in the driver. For backwards
compatibility the old code is left in place for msm8916 and qcs404, two
platforms which have in-tree DT files. For msm8974 the original function
is left intact, since it differs significantly (and I can not test the
code on msm8974). For all other affected platforms the old parsing code
has been dropped as a part of this RFC.
The code was tested on msm8916 and qcs404 only, thus it is being sent as
an RFC.
