2022-09-19wifi: brcmfmac: of: Fetch Apple propertiesHector Martin
On Apple ARM64 platforms, firmware selection requires two properties that come from system firmware: the module-instance (aka "island", a codename representing a given hardware platform) and the antenna-sku. We map Apple's module codenames to board_types in the form "apple,<module-instance>". The mapped board_type is added to the DTS file in that form, while the antenna-sku is forwarded by our bootloader from the Apple Device Tree into the FDT. Grab them from the DT so firmware selection can use them.

2022-09-19wifi: brcmfmac: pcie: Read Apple OTP informationHector Martin
On Apple platforms, the One Time Programmable ROM in the Broadcom chips contains information about the specific board design (module, vendor, version) that is required to select the correct NVRAM file. Parse this OTP ROM and extract the required strings. Note that the user OTP offset/size is per-chip. This patch does not add any chips yet.

2022-09-19wifi: brcmfmac: firmware: Support passing in multiple board_typesHector Martin
Apple platforms have firmware and config files identified with multiple dimensions. We want to be able to find the most specific firmware available for any given platform, progressively trying more general firmwares. To do this, first add support for passing in multiple board_types, which will be tried in sequence. Since this will cause more log spam due to missing firmwares, also switch the secondary firmware fecthes to use the _nowarn variant, which will not log if the firmware is not found.

Now that the firmware fetcher can handle per-board CLM files, load the CLM blob alongside the other firmware files and change the bus API to just return the existing blob, instead of fetching the filename. This enables per-board CLM blobs, which are required on Apple platforms.

This binding is currently used for SDIO devices, but these chips are also used as PCIe devices on DT platforms and may be represented in the DT. Re-use the existing binding and add chip compatibles used by Apple T2 and M1 platforms (the T2 ones are not known to be used in DT platforms, but we might as well document them).

2022-09-18wifi: iwlwifi: mvm: trigger resume flow before wait for notificationsHaim, Dreyfuss
We have recently enabled resume flow based on notifications. These notifications are sent by the FW when completing the resume flow. From IWL_DEVICE_FAMILY_AX210 the resume flow is triggered by the transport layer on iwl_trans_d3_resume. On IWL_DEVICE_FAMILY_22000 and earlier we trigger the resume flow by sending the D0I3 command. Currently, we are waiting for the notifications before sending the command, the notifications won't be sent by the FW since there is no resume trigger to piggyback on. Send the command before starting the wait flow to fix it.

2022-09-18wifi: iwlwifi: mvm: Add support for wowlan info notificationHaim Dreyfuss
IMR (Isolated Memory Regions) is a mechanism to protect memory regions from unwarranted access by agents in the system that should not have access to that memory. When IMR is enabled, pages in the DRAM will be located within the IMR memory space, accessible only by the device. As a side effect, during S4 (a.k.a hibernate) the IMR memory space is not retained. While the DRAM is saved to the disk and restored by the OS upon resume, the IMR, which is hidden from the OS neither saved upon suspend nor restored upon resume. As a consequence of the above, it turned out that commands cannot be sent as part of the resume flow, and so after ending d3 the FW needs to use notifications instead of cmd-resp. The resume flow becomes asynchronous, with a series of notifications, starting with wowlan_info_notif, through wowlan_pkt_notif and complete the resume flow by d3_end_notif. This patch adds the support for wowlan info notification. The wake packet has been removed from the wowlan info struct and will be handled in a dedicated notification.

2022-09-15wifi: mt76: mt7921: get rid of the false positive resetSean Wang
False positive reset would be possibly triggered by those commands we applied in suspend with HZ MCU timeout, especially it happened when we enabled kernel log in pm core to diagnose how much time we spend in each driver during suspend procedure. So we enlarge the value and align the MCU timeout as other commands we did to reduce the false positive reset.

2022-09-15wifi: mt76: add PPDU based TxS support for WED deviceRyder Lee
Given that there's no data coming from network stack for binding flows, hence driver counts and reports station's statistics directly through NL80211_STA_INFO_* based on active PPDU based TxS for offloading data. Apart from that, WA firmware and its offloading engine (SDO) have hardcoded "2" as PID, so we introduce MT_PACKET_ID_WED to differentiate WED reporting. Note that PPDU format TxS is mutually exclusive with MT_TXD5_TX_STATUS_HOST.

2022-09-15wifi: mt76: sdio: poll sta stat when device transmits dataSean Wang
It is not meaningful to poll sta stat when there is no data traffic. So polling sta stat when the device has transmitted data instead to save CPU power. That implies that it is unallowed the stat_work to work while MCU is being initialized in the really early stage to fix the possible time to time MCU initialization failure.

2022-09-15wifi: mt76: sdio: fix the deadlock caused by sdio->stat_workSean Wang
Because wake_work and sdio->stat_work share the same workqueue mt76->wq, if sdio->stat_work cannot acquire the mutex lock such as that was possibly held up by [mt7615, mt7921]_mutex_acquire. Additionally, if [mt7615, mt7921]_mutex_acquire was called by sdio->stat_work self, the wake would be blocked by itself. Thus, we move the stat_work into ieee80211_workqueue instead to break the deadlock.
