According to the msm-3.18 vendor kernel from Qualcomm, mdm9607 needs "correction factors" to adjust for additional offsets observed after the factory calibration values in the fuses [1, 2]. The fixed offsets should be applied unless there is a special calibration mode value that indicates that no offsets are needed [3]. Note that the new calibration mode values are called differently in this patch compared to the vendor kernel: - TSENS_TWO_POINT_CALIB_N_WA -> ONE_PT_CALIB2_NO_OFFSET - TSENS_TWO_POINT_CALIB_N_OFFSET_WA -> TWO_PT_CALIB_NO_OFFSET This is because close inspection of the calibration function [3] reveals that TSENS_TWO_POINT_CALIB_N_WA is actually a "one point" calibration because the if statements skip all "point2" related code for it.
