Introduce radar/CAC background detection support for mt7915 driver
Background radar/CAC detection allows to avoid the CAC downtime
switching on a different channel during CAC detection on the selected
radar channel.
Changes since v1:
- repost adding devicetree ml in cc
Lorenzo Bianconi (6):
mt76: mt7915: introduce mt7915_set_radar_background routine
mt76: mt7915: enable radar trigger on rdd2
mt76: mt7915: introduce rdd_monitor debugfs node
mt76: mt7915: report radar pattern if detected by rdd2
mt76: mt7915: enable radar background detection
dt-bindings:net:wireless:mediatek,mt76: add disable-radar-offchan
