====================
wireless-drivers-next patches for v5.11

First set of patches for v5.11. rtw88 getting improvements to work
better with Bluetooth and other driver also getting some new features.
mhi-ath11k-immutable branch was pulled from mhi tree to avoid
conflicts with mhi tree.

Major changes:

rtw88
 * major bluetooth co-existance improvements
wilc1000
 * Wi-Fi Multimedia (WMM) support
ath11k
 * Fast Initial Link Setup (FILS) discovery and unsolicited broadcast
   probe response support
 * qcom,ath11k-calibration-variant Device Tree setting
 * cold boot calibration support
 * new DFS region: JP
wnc36xx
 * enable connection monitoring and keepalive in firmware
ath10k
 * firmware IRAM recovery feature
mhi
 * merge mhi-ath11k-immutable branch to make MHI API change go smoothly

* tag 'wireless-drivers-next-2020-12-03' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next: (180 commits)
