Subject: [PATCH] wifi: rt2x00: correct wrong BBP register in RxDCOC
|
|
calibration
|
|
|
|
Refer to Mediatek vendor driver RxDCOC_Calibration() function, when
|
|
performing gainfreeze calibration, we should write register 140
|
|
instead of 141. This fix can reduce the total calibration time from
|
|
6 seconds to 1 second.
