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

2026-03-04T12:20:31+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: pci: validate release report content before using for RTL8922DE

2026-03-04T12:20:29+00:00

[ Upstream commit 5f93d611b33a05bd03d6843c8efe8cb6a1992620 ] The commit 957eda596c76 ("wifi: rtw89: pci: validate sequence number of TX release report") does validation on existing chips, which somehow a release report of SKB becomes malformed. As no clear cause found, add rules ahead for RTL8922DE to avoid crash if it happens.

[ 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

2026-03-04T12:20:28+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

[ 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.
