The NV item NV_WCDMA_TX_LIN_VS_TEMP_0 contains a table of eight adjustment values
for the Tx linearizer in PA_Range0 (lowest PA power state), based on temperature. Each element
corresponds to an AGC adjustment value for a given temperature. For a given temperature, each
offset in the Tx linearizer curve is adjusted by a constant amount based on this table. For example,
if for a given temperature index, the element in this table is 0x05, each of the 32 offsets in the
adjusted master curve table will be increased by 5, when the temperature corresponds to that given
index. Based on the temperature, an appropriate bin in the array is picked for compensation.
Default value is set to [0, 0, 0, 0, 0, 0, 0, 0] if there is no temperature compensation required. For
RTR6285/6280-based platforms, this NV item must be calibrated and the values should be nonzero.
