ath11k: add debugfs for TWT debug calls
New debugfs files to manually add/delete/pause/resume TWT dialogs for test/debug purposes. The debugfs files expect the following parameters - Add dialog echo '<Peer_MAC> <Dialog_ID> <Wake_Interval_Usec> <Wake_Interval_Mantis> <Wake_Duration_Usec> <First_SP_Offset> <TWT_Command> <1:Broadcast /0:Individual> <1:Triggered / 0:Untriggered> <1:Unannounced /0:Announced> <1:Protected / 0:Unprotected>' > /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/add_dialog Example (Non-triggered and un-announced): echo '00:03:7F:20:13:52 1 102400 100 30720 20480 4 0 0 1 0' > /sys/kernel/debug/ieee80211/phy0/netdev:wlan0/twt/add_dialog - Delete dialog echo '<Peer_MAC> <Dialog_ID>' > /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/del_dialog - Pause dialog echo '<Peer_MAC> <Dialog_ID>' > /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/pause_dialog - Resume dialog echo '<Peer_MAC> <Dialog_ID> <SP_Offset_Usec> <Next_TWT_Size>' > /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/resume_dialog Example: echo '00:03:7F:20:13:52 1 2000000 3' > /sys/kernel/debug/ieee80211/phy0/netdev:wlan0/twt/resume_dialog Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-01179-QCAHKSWPL_SILICONZ-1 Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: Aloka Dixit <alokad@codeaurora.org> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/20220131031043.1295-2-alokad@codeaurora.org
