ODM verified that on Noble with this firmware (20240318.git3b128b60-0ubuntu2.11), Power House Mountain report showed that, although the controller still turn back to L0 during suspend occasionally, it return to L1 immediately and the duration is negligible. Consider this has been fixed.

This will make the ESTAR test fail on those platforms. [ Fix ] Mediatek has upstreamed an updated firmware to resolve this issue: 15442c631 (linux-firmware: update firmware for MT7920 WiFi device) [ Test ] 1. Install the linux-firmware and boot. Check dmesg. he kernel should load the firmware without error. 2. Run the Power House Mountain test and confirm that MT7920 stays in L1/L2 states during s2idle. 3. Insert SIM card and confirm basic WWAN and WiFi function. [ Where the problems could occur ] If firmware is not correctly loaded or corrupted, this may render WiFi and WWAN unusable for modules that use MT7920.
