====================
wireless-drivers-next patches for v5.16

Second set of patches for v5.16 and this time we have a big one. We
have the new Realtek driver rtw89 with over 90 kLOC and also over 150
patches for mt76. ath9k also got few new small features. And the usual
cleanups and fixes all over.

Major changes:

rtw89
 * new Realtek 802.11ax driver
 * supports Realtek 8852AE 802.11ax 2x2 chip

ath9k
 * add option to reset the wifi chip via debugfs
 * convert Device Tree bindings to the json-schema
 * support Device Tree ieee80211-freq-limit property to limit channels

mt76
 * mt7921 aspm support
 * mt7921 testmode support
 * mt7915 LED support
 * mt7921 6GHz band support
 * support for eeprom data in DT
 * mt7915 TWT support
 * mt7921s SDIO support

* tag 'wireless-drivers-next-2021-10-22' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next: (213 commits)
  zd1201: use eth_hw_addr_set()
  wl3501_cs: use eth_hw_addr_set()
  ray_cs: use eth_hw_addr_set()
