Bug Description
[kernel SRU Justification]
[Impact]
Mediatek MT7925 WiFi/Bluetooth not supported yet.
[Fix]
For WiFi, there are tons of patches to be backported from upstream kernel v6.7 due to a massive refactoring was done to integrate multiple mt79xx drivers into one before landing support for mt7925. While these changes, mostly clean cherry-picks, are tied to each other, and separating them may cause more efforts in the future, a huge patchset of total number 144 is proposed.
For Bluetooth, upstream commit 4c92ae75ea7d ("Bluetooth: btusb: Add support Mediatek MT7925") is required.
[Test Case]
Initial hardware support. One should be able to find WiFi/BT interfaces up available along with proposed kernels.
[Where problems could occur]
Features for MT7925 are not all available at this moment, and expect more fixes for every corner case.
[Other Info]
MT7925 is supported since v6.7, and we need it for oem-6.5 as well. Nominate for Jammy and Noble.
