wifi: rtw89: pci: restore LDO setting after device resume

2026-03-04T12:21:17+00:00

[ Upstream commit af1e82232b988f8fc6d635c60609765e49221a64 ] The LDO (Low Dropout Regulator) setting is missing after suspend/resume in some platforms, and it will cause card loss. Therefore, reconfigure this setting to avoid it.

wifi: rtw89: 8922a: add digital compensation for 2GHz

[ Upstream commit 8da7e88682d58a7c2e2c2101e49d3c9c9ac481b0 ] This fixes transmit power too low under 2GHz connection. Previously we missed the settings of 2GHz, add the according calibrated tables.

wifi: rtw89: fix unable to receive probe responses under MLO connection

2026-03-04T12:21:15+00:00

[ Upstream commit 6f6d7a325fbde4f025ee1b1277f6f44727e21223 ] During MLO connections, A1 of the probe responses we received are in link address, these frames will then be dropped by mac80211 due to not matching the MLD address in ieee80211_scan_accept_presp(). Fix this by using MLD address to scan when not using random MAC address.

wifi: rtw89: wow: add reason codes for disassociation in WoWLAN mode

2026-03-04T12:21:12+00:00

[ Upstream commit 2fd8f953f25173d14981d8736b6f5bfcd757e51b ] Some APs disconnect clients by sending a Disassociation frame rather than a Deauthentication frame. Since these frames use different reason codes in WoWLAN mode, this commit adds support for handling Disassociation to prevent missed disconnection events.

wifi: rtw89: mac: correct page number for CSI response

[ Upstream commit aa2a44d0d22d45d659b9f01638809b1735e46cff ] For beamforming procedure, hardware reserve memory page for CSI response. The unit of register is (value - 1), so add one accordingly as expected.

wifi: rtw88: Fix inadvertent sharing of struct ieee80211_supported_band data

2026-03-04T12:21:11+00:00

[ Upstream commit fcac0f23d4d20b11014a39f8e2527cdc12ec9c82 ] Internally wiphy writes to individual channels in this structure, so we must not share one static definition of channel list between multiple device instances, because that causes hard to debug breakage. For example, with two rtw88 driven devices in the system, channel information may get incoherent, preventing channel use.

wifi: rtw89: 8922a: set random mac if efuse contains zeroes

2026-03-04T12:21:11+00:00

[ Upstream commit 41be33d3efc120f6a2c02d12742655f2aa09e1b6 ] I have some rtl8922ae devices with no permanent mac stored in efuse. It could be properly saved and/or configured from user tools like NetworkManager, but it would be desirable to be able to initialize it somehow to get the device working by default. So, in the same way as with other devices, if the mac address read from efuse contains zeros, a random mac address is assigned to at least allow operation, and the user is warned about this in case any action needs to be considered.
