chip_allow_sleep() only supported wakeup via SDIO, which made the driver unusable over SPI. This code is a straight forward port from the driver in the linux-at91 repository.

2021-03-15rtw88: remove unnecessary variablewengjianfeng1-2/+1
The variable ret is defined at the beginning and initialized to 0 until the function returns ret, and the variable ret is not reassigned.Therefore, we do not need to define the variable ret, just return 0 directly at the end of the function.

ath.git patches for v5.13. Major changes: ath11k * add initial support for QCN9074, but not enabled yet due to firmware problems * enable radar detection for 160MHz secondary segment * handle beacon misses in station mode
2021-03-09ath11k: Add support for STA to handle beacon missLavanya Suresh4-13/+81
When AP goes down without any indication to STA, firmware detects missing beacon, and sends wmi roam event with reason BEACON_MISS to the host. Added support for STA mode to trigger disassociation from AP, on receiving this event from firmware.

Currently, though the peer rssi information is updated to station dump from driver sta_statistics mac op, the info doesn't get updated since the NL80211_STA_INFO_SIGNAL filled flag is not set in station info.

2021-03-09ath10k: skip the wait for completion to recovery in shutdown pathYoughandhar Chintala1-9/+20
Currently in the shutdown callback we wait for recovery to complete before freeing up the resources. This results in additional two seconds delay during the shutdown and thereby increase the shutdown time. As an attempt to take less time during shutdown, remove the wait for recovery completion in the shutdown callback and added an API to freeing the reosurces in which they were common for shutdown and removing the module.

2021-03-06ath10k: Detect conf_mutex held ath10k_drain_tx() callsShuah Khan1-0/+2
ath10k_drain_tx() must not be called with conf_mutex held as workers can use that also. Add call to lockdep_assert_not_held() on conf_mutex to detect if conf_mutex is held by the caller. The idea for this patch stemmed from coming across the comment block above the ath10k_drain_tx() while reviewing the conf_mutex holds during to debug the conf_mutex lock assert in ath10k_debug_fw_stats_request(). Adding detection to assert on conf_mutex hold will help detect incorrect usages that could lead to locking problems when async worker routines try to call this routine.

2021-02-24ath11k: fix AP mode for QCA6390Kalle Valo1-2/+2
Commit c134d1f8c436 ("ath11k: Handle errors if peer creation fails") completely broke AP mode on QCA6390: kernel: [ 151.230734] ath11k_pci 0000:06:00.0: failed to create peer after vdev start delay: -22 wpa_supplicant[2307]: Failed to set beacon parameters wpa_supplicant[2307]: Interface initialization failed wpa_supplicant[2307]: wlan0: interface state UNINITIALIZED->DISABLED wpa_supplicant[2307]: wlan0: AP-DISABLED wpa_supplicant[2307]: wlan0: Unable to setup interface. wpa_supplicant[2307]: Failed to initialize AP interface This was because commit c134d1f8c436 ("ath11k: Handle errors if peer creation fails") added error handling for ath11k_peer_create(), which had been failing all along but was unnoticed due to the missing error handling. The actual bug was introduced already in commit aa44b2f3ecd4 ("ath11k: start vdev if a bss peer is already created"). ath11k_peer_create() was failing because for AP mode the peer is created already earlier op_add_interface() and we should skip creation here, but the check for modes was wrong. Fixing that makes AP mode work again. This shouldn't affect IPQ8074 nor QCN9074 as they have hw_params.vdev_start_delay disabled.

2021-02-22Revert "ath9k: fix ath_tx_process_buffer() potential null ptr dereference"Shuah Khan1-16/+12
This reverts commit a56c14bb21b296fb6d395164ab62ef2e419e5069. ath_tx_process_buffer() doesn't dereference or check sta and passes it to ath_tx_complete_aggr() and ath_tx_complete_buf(). ath_tx_complete_aggr() checks the pointer before use. No problem here. ath_tx_complete_buf() doesn't check or dereference sta and passes it on to ath_tx_complete(). ath_tx_complete() doesn't check or dereference sta, but assigns it to tx_info->status.status_driver_data[0] ath_tx_complete_buf() is called from ath_tx_complete_aggr() passing null ieee80211_sta pointer. There is a potential for dereference later on, if and when the tx_info->status.status_driver_data[0]is referenced. In addition, the rcu read lock might be released before referencing the contents. ath_tx_complete_buf() should be fixed to check sta perhaps? Worth looking into. Reverting this patch because it doesn't solve the problem and introduces memory leak by skipping buffer completion if the pointer (sta) is NULL.

2021-02-18mt76: fix tx skb error handling in mt76_dma_tx_queue_skbFelix Fietkau1-9/+6
When running out of room in the tx queue after calling drv->tx_prepare_skb, the buffer list will already have been modified on MT7615 and newer drivers. This can leak a DMA mapping and will show up as swiotlb allocation failures on x86. Fix this by moving the queue length check further up. This is less accurate, since it can overestimate the needed room in the queue on MT7615 and newer, but the difference is small enough to not matter in practice.

2021-02-18ath9k: fix transmitting to stations in dynamic SMPS modeFelix Fietkau2-1/+8
When transmitting to a receiver in dynamic SMPS mode, all transmissions that use multiple spatial streams need to be sent using CTS-to-self or RTS/CTS to give the receiver's extra chains some time to wake up. This fixes the tx rate getting stuck at <= MCS7 for some clients, especially Intel ones, which make aggressive use of SMPS.

QCN9074 is PCI based 11ax radio. - has 2G/5G/6G variants. - has NSS 2x2 and 4x4 variants. QCN9074 uses 45MB of HOST DDR memory, target requests host memory in segments, each segment is of 2MB size and is physcial contiguous and use static window configuration. Currently there are still two issues with QCN9074, see below. So we don't add QCN9074 PCI id yet to make sure the driver is loaded. The id will be added only after the issues are fixed.

2021-02-16ath9k: fix ath_tx_process_buffer() potential null ptr dereferenceShuah Khan1-12/+16
ath_tx_process_buffer() references ieee80211_find_sta_by_ifaddr() return pointer (sta) outside null check. Fix it by moving the code block under the null check. This problem was found while reviewing code to debug RCU warn from ath10k_wmi_tlv_parse_peer_stats_info() and a subsequent manual audit of other callers of ieee80211_find_sta_by_ifaddr() that don't hold RCU read lock.

2021-02-15b43: N-PHY: Fix the update of coef for the PHY revision >= 3caseColin Ian King1-1/+1
The documentation for the PHY update [1] states: Loop 4 times with index i If PHY Revision >= 3 Copy table[i] to coef[i] Otherwise Set coef[i] to 0 the copy of the table to coef is currently implemented the wrong way around, table is being updated from uninitialized values in coeff. Fix this by swapping the assignment around.

Kalle Valo says: ==================== wireless-drivers-next patches for v5.12 Second set of patches for v5.12. Last time there was a smaller pull request so unsurprisingly this time we have a big one. mt76 has new hardware support and lots of new features, iwlwifi getting new features and rtw88 got NAPI support. And the usual cleanups and fixes all over. Major changes: ath10k * support setting SAR limits via nl80211 rtw88 * support 8821 RFE type2 devices * NAPI support iwlwifi * add new FW API support * support for new So devices * support for RF interference mitigation (RFI) * support for PNVM (Platform Non-Volatile Memory, a firmware data file) from BIOS mt76 * add new mt7921e driver * 802.11 encap offload support * support for multiple pcie gen1 host interfaces on 7915 * 7915 testmode support * 7915 txbf support brcmfmac * support for CQM RSSI notifications wil6210 * support for extended DMG MCS 12.1 rate ==================== Signed-off-by: David S.
