iwlwifi: Adjust blink rate to compensate Clock difference
Adjust led blink rate to compensate on a MAC Clock difference on every HW. Led blink rate analysis showed an average deviation of 0% on 3945, 5% on 4965 HW and 20% on 5000 series and up. Need to compensate on the led on/off time per HW according to the deviation to achieve the desired led frequency The calculation is: (100-averageDeviation)/100 * blinkTime For code efficiency the calculation will be: compensation = (100 - averageDeviation) * 64 / 100 NewBlinkTime = (compensation * BlinkTime) / 64 Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
