I like the function name, but it's not really common for tsens, it's
just common for tsens v2. Also as patch 4 shows we end up adding a set
of essentially empty platform specific files for referencing this
function.

I would suggest that you instead rename tsens-8996.c to tsens-v2.c,
rename ops_8996 to ops_v2 and either add new tsens_data for each
platform or simply rename that too to data_v2 which we point to from
tsens_table.

I think we should take it once step further and add "qcom,tsens-v2" as a
valid compatible in tsens_table and make the dts do:

	comaptible = "qcom,msm8996-tsens", "qcom,tsens-v2";

and
	compatible = "qcom,sdm845-tsens", "qcom,tsens-v2";
