651 * 4965 temperature calculation.
652 *
653 * The driver must calculate the device temperature before calculating
654 * a txpower setting (amplifier gain is temperature dependent). The
655 * calculation uses 4 measurements, 3 of which (R1, R2, R3) are calibration
656 * values used for the life of the driver, and one of which (R4) is the
657 * real-time temperature indicator.
658 *
659 * uCode provides all 4 values to the driver via the "initialize alive"
660 * notification (see struct iwl4965_init_alive_resp). After the runtime uCode
661 * image loads, uCode updates the R4 value via statistics notifications
662 * (see STATISTICS_NOTIFICATION), which occur after each received beacon
663 * when associated, or can be requested via REPLY_STATISTICS_CMD.
664 *
665 * NOTE: uCode provides the R4 value as a 23-bit signed value. Driver
666 * must sign-extend to 32 bits before applying formula below.
667 *
668 * Formula:
669 *
670 * degrees Kelvin = ((97 * 259 * (R4 - R2) / (R3 - R1)) / 100) + 8
671 *
672 * NOTE: The basic formula is 259 * (R4-R2) / (R3-R1). The 97/100 is
673 * an additional correction, which should be centered around 0 degrees
674 * Celsius (273 degrees Kelvin). The 8 (3 percent of 273) compensates for
675 * centering the 97/100 correction around 0 degrees K.
676 *
677 * Add 273 to Kelvin value to find degrees Celsius, for comparing current
678 * temperature with factory-measured temperatures when calculating txpower
679 * settings.
