Introduce support for mt7921e 802.11ax (Wi-Fi 6) 2x2:2SS chipset.
v2:
- Mark the patch as -next
v3:
- Remove sw scan support
- Get rid of dbdc code
- Run mt7921_configure_filter hodling mt76 mutex
- Correct Txp programming in Txd
- Correct fw log to host command
- Correct eeprom offset definition
- Update rate adaption info report
- Remove unused code and fields in struture
- Split the previous driver into several patches for easy review
v4:
- introduce sched scan support
- introduce 802.11 PS support in sta mode
- introduce support for hardware beacon filter
- introduce beacon_loss mcu event
- introduce PM support
- refine sta_rec_phy and add sta_rec_ra_info
- remove incorrect mt7921_mcu_tx_config member
- fix erroneous endianness conversion in mt7921_tx_complete_skb()
- fix endianness warning in mt7921_get_wtbl_info()
- fix endianness warnings in mt7921_mcu_sta_tlv()
- remove unused code in mt7921_mcu_send_message
- remove scan with random mac until fw is ready
- channel domain is added for hw scan
v5:
- fix implicit conversion from enumeration type
- remove unused function declaration
- drop zero-length packet to avoid Tx hang
- fix MT_CIPHER_BIP_CMAC_128 setkey
- reset token when mac_reset happens
- create mac.h when mac support is added
- reorder the patch of adding module support
- move mac_work in mt76_core module
- move chainmask in mt76_phy
- rebase per moving mac_work in mt76_core module
- rebase per moving chainmask in mt76_phy
v6:
- use UNI_BSS_INFO_BCNFT and UNI_BSS_INFO_PS to carry out
enabling hardware beacon filter and 802.11 power saving
mode according to the MT7921 firmware
v7:
- remove the merged patches
- rebase onto the series mt76: introduce mt76_connac common module
https://patchwork.kernel.org/project/linux-wireless/list/?series=418597
- rely on mt76_connac_mcu common library
- rely on mt76_connac_mcu module for sched_scan and hw_scan
- rely on mt76_connac_mcu module for suspend and WoW support
- introduce regdomain notifier support
- enable MSI interrupts
- introduce Runtime PM support
- add coredump support
- add sta statistics
- disable Rx header translation on default
- set nss to 2 on default

Introduce coredump support to mt7921 driver.
The coredump would be produced when MCU met the fatal error or driver

From: Sean Wang <[email protected]>
Introduce support for hw beacon filter available in the mt7921 firmware.
According to mt7921e firmware, enabling hardware filter would rely on
mt7921_mcu_uni_bss_bcnft and disabling hardware filter still rely on legacy
mt7921_mcu_set_bss_pm.

If device has enabled beacon hw filter rx beacons are not reported to
the host. Introduce beacon_loss mcu event to trigger mac80211 mlme
connection state machine in this configuration.
IEEE80211_VIF_BEACON_FILTER has not set in vif flags since hw beacon
filter is not enabled yet

MT7921 contains a microprocessor with which the host can use command/event
to communicate to implement offload features such as establish connection,
hardware scan and so on. The host has to download the ROM patch, RAM
firmware and finally activate the MCU to complete the MT7921
initialization.

why didn't you just merge this into [-next,v7,05/22] mt76: mt7921: add
