Merge tag 'wireless-drivers-next-2021-12-23' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next
Kalle Valo says: ==================== wireless-drivers-next patches for v5.17 Third set of patches for v5.17, and the final one if all goes well. We have Specific Absorption Rate (SAR) support for both mt76 and rtw88. Also iwlwifi should be now W=1 warning free. But otherwise nothing really special this time, business as usual. Major changes: mt76 * Specific Absorption Rate (SAR) support * mt7921: new PCI ids * mt7921: 160 MHz channel support iwlwifi * fix W=1 and sparse warnings * BNJ hardware support * add new killer device ids * support for Time-Aware-SAR (TAS) from the BIOS * Optimized Connectivity Experience (OCE) scan support rtw88 * hardware scan * Specific Absorption Rate (SAR) support ath11k * qca6390/wcn6855: report signal and tx bitrate * qca6390: rfkill support * qca6390/wcn6855: regdb.bin support ath5k * switch to rate table based lookup wilc1000 * spi: reset/enable GPIO support * tag 'wireless-drivers-next-2021-12-23' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next: (148 commits) mt76: mt7921: fix a possible race enabling/disabling runtime-pm wilc1000: Document enable-gpios and reset-gpios properties wilc1000: Add reset/enable GPIO support to SPI driver wilc1000: Convert static "chipid" variable to device-local variable rtw89: 8852a: correct bit definition of dfs_en rtw88: don't consider deep PS mode when transmitting packet ath11k: Fix unexpected return buffer manager error for QCA6390 ath11k: add support of firmware logging for WCN6855 ath11k: Fix napi related hang ath10k: replace strlcpy with strscpy rtw88: support SAR via kernel common API rtw88: 8822c: add ieee80211_ops::hw_scan iwlwifi: mei: wait before mapping the shared area iwlwifi: mei: clear the ownership when the driver goes down iwlwifi: yoyo: fix issue with new DBGI_SRAM region read. iwlwifi: fw: fix some scan kernel-doc iwlwifi: pcie: make sure prph_info is set when treating wakeup IRQ iwlwifi: mvm: remove card state notification code iwlwifi: mvm: drop too short packets silently iwlwifi: mvm: fix AUX ROC removal ... ==================== Link: https://lore.kernel.org/r/20211223141108.78808C36AE9@smtp.kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
