[RFC 0/5] use standard signature for mt7603 mcu api

[Lorenzo Bianconi]

Introduce mt76_mcu_ops data structure in mt7603 mcu code in order to
unify mcu code between mt7603 and mt7615 drivers

Lorenzo Bianconi (5):
  mt7603: remove query from mt7603_mcu_msg_send signature
  mt7603: use standard signature for mt7603_mcu_msg_send
  mt7603: initialize mt76_mcu_ops data structure
  mt76: introduce mt76_mcu_restart macro
  mt7603: init mcu_restart function pointer

[RFC 1/5] mt7603: remove query from mt7603_mcu_msg_send signature

[Lorenzo Bianconi]

Remove query parameter from mt7603_mcu_msg_send/__mt7603_mcu_msg_send
routine signature since it can be obtained from cmd value. This is a
preliminary patch for mcu code unification between mt7615 and mt7603
drivers

[RFC 2/5] mt7603: use standard signature for mt7603_mcu_msg_send

[Lorenzo Bianconi]

Use mt76 common signature for mt7603_mcu_msg_send. Move skb allocation
in mt7603_mcu_msg_send and remove duplicated code. This is a preliminary
patch for mt7615-mt7603 mcu code unification
