From: Sean Wang <[e-mail]>

The patchset adds the SDIO support to the MT7921 driver, basically are
made up of 3 parts.

PART 1: patch 1-5, 8-9 and 13-15
These are preliminary patches for mt7921s driver to refactor and reuse the
current mt7921e driver as much as possible.

PART 2: patch 6-7, 10-11
These are preliminary patches for mt7921s driver to refactor and reuse the
current mt7663s driver as much as possible.

PART 3: patch 12 and 16-17
These are specific patches for mt7921s driver and reset mechanism in the
same framework where mt7921e have been supported. 

The patchset are built and generated against the current mt76 with the
tag mt76-for-kvalo-2021-10-12 plus the extra pending patches [1] expected to
be merged to mt76 tree soon to help the review and merge process be easier.

The change list from v1 to v2
1. rework the whole driver according to the new patches added
   ("mt76: introduce __mt76_mcu_send_firmware routine"),
   ("mt76: not accounting the MCU header size in __mt76_mcu_send_firmware for mt7915/21") and
   ("mt76: sdio: move common code in mt76_sdio module")
2. drop pci_init.c and sdio_init.c by moving the related logic to pci.c and sdio.c, respectively.
3. cosmetics the patches like removing unnecessary new line, adding an extra space to fixed_map table and so on ...
4. fix typo in commit message

The change list from v2 to v3
1. rebase onto the latest mt76 branch
2. update per Lorenzo comments on v2
3. fix scheduling while atomic in mt7921_mac_sta_poll for mt7921s driver

The change list from v3 to v4
1. change the title of coverletter
2. fix the git message in patch 14
3. rebase onto the mt76-for-kvalo-2021-10-12

The change list from v4 to v5
1. fix endianess warning in mt76_connac_mcu_parse_tx_resource
2. rework the driver with the the following additional patches
   a. mt76: sdio: introduce parse_irq callback
   b. mt76: sdio: export mt76s_alloc_rx_queue and mt76s_alloc_tx routines
