The firmware support for management frame protection has limitations:
- do not support cipher BIP-GMAC-128 and BIP-GMAC-256
- support cipher BIP-CMAC-128 and BIP-CMAC-256, except action frame with
action type 'not robust'.
Therefore, to simplify the logic, do not set the IGTK to firmware and
let the encryption of management frames be handled by upper layer.

MediaTek's controller driver on COB platform (e.g. MT8188) is
capable of controlling power supplies and reset pin of a component
(e.g. a WIFI chip) in power-on and power-off process.
Due to this optional feature, mt76 need to inform controller
that mt76 need to keep power during suspend. Otherwise WIFI will be
powered off when system enters suspend process.
The "wakeup-source" property was used for the device that need
this to go into suspend mode so that mt76 suspend handler doesn't
fail and the system is able to enter into a suspend state.

wifi: mt7921@0 {

reg = <0x0000 0 0 0 0>;
