Merge tag 'wireless-drivers-next-2020-03-05' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next
Kalle Valo says: ==================== wireless-drivers-next patches for v5.7 First set of patches for v5.7. Lots of mt76 patches as they missed the v5.6 deadline and hence they were postponed to the next version. Otherwise nothing special standing out. mt76 Major changes: * dual-band concurrent support for MT7615 * fixes for rx path race conditions * coverage class support for MT7615 * beacon fixes for USB devices * MT7615 LED support * set_antenna support for MT7615 * tracing improvements * preparation for supporting new USB devices * tx power fixes brcmfmac * support BRCM 4364 found in MacBook Pro 15,2 ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
