[PATCH 0/9] add preliminary usb support to mt7615 driver

[Lorenzo Bianconi]

This is the first preliminary series to add support to mt7663u driver
This series is based on 'mt7663 driver update'
https://patchwork.kernel.org/cover/11470699/

Lorenzo Bianconi (9):
  mt76: add headroom and tailroom to mt76_mcu_ops data structure
  mt76: mt7615: introduce mt7663u support to mt7615_write_txwi
  mt76: mt7615: introduce mt7615_mac_update_rate_desc routine
  mt76: mt7615: introduce __mt7663_load_firmware routine
  mt76: mt7615: move mt7615_mac_wtbl_addr in mac.h
  mt76: mt76u: rely on mt7622 queue scheme for mt7663u
  mt76: mt7615: rework wtbl key configuration
  mt76: mt7615: introuce mt7615_wtbl_desc data structure
  mt76: mt7615: add address parameter to mt7615_eeprom_init

[PATCH 1/9] mt76: add headroom and tailroom to mt76_mcu_ops data structure

[Lorenzo Bianconi]

Introduce headroom and tailroom to mt76_mcu_ops data structure in order
to unify the routine used for mcu message allocation. This is a
preliminary patch to add mt7663u support

[PATCH 7/9] mt76: mt7615: rework wtbl key configuration

[Lorenzo Bianconi]

Remove key dependency from mt7615_mac_wtbl_update_key and export
mt7615_mac_wtbl_update_key, mt7615_mac_wtbl_update_pk and
mt7615_mac_wtbl_update_cipher in order to reuse them in usb code.
Move mt7615_mac_get_cipher in mac.h
