/********************* START TEMPERATURE *************************************/

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