To reduce register IO, combine set_gnt_wl/set_gnt_bt to set the same register one time. Because RTL8852C use different register to control antenna path, so make correction of path control related debug logs. Signed-off-by:

Show TDMA information containing TDMA policy and time slot of Wi-Fi/BT in debug message to check things are in expected. The v1 format contains additional header, and remaining part is the same as original. So 8852CE selects v1 version, and then everything like original. Signed-off-by:

Parsing firmware error message from original version and v1 reports to show up exception counter of commands from firmware in debug message. Then, we can make sure exchange commands are correct totally. In the later version Wi-Fi firmware(v1), the report format was changed. With this update, we can yield correct report from proper struct.

These newer PCIe core revisions include new sets of registers that must be used instead of the legacy ones. Introduce a brcmf_pcie_reginfo to hold the specific register offsets and values to use for a given platform, and change all the register accesses to indirect through it. Reviewed-by:

Newer chips used on Apple platforms have a max_rxbufpost greater than 512, which causes warnings when brcmf_msgbuf_rxbuf_data_fill tries to put more entries in the ring than will fit. Increase the ring sizes to 1024. Reviewed-by:

On Device Tree platforms, it is customary to be able to set the MAC address via the Device Tree, as it is often stored in system firmware. This is particularly relevant for Apple ARM64 platforms, where this information comes from system configuration and passed through by the bootloader into the DT. Implement support for this by fetching the platform MAC address and adding or replacing the macaddr= property in nvram. This becomes the dongle's default MAC address. On platforms with an SROM MAC address, this overrides it. On platforms without one, such as Apple ARM64 devices, this is required for the firmware to boot (it will fail if it does not have a valid MAC at all). Reviewed-by:

On Apple platforms, firmware selection uses the following elements: Property Example Source ============== ======= ======================== * Chip name 4378 Device ID * Chip revision B1 OTP * Platform shikoku DT (ARM64) or ACPI (x86) * Module type RASP OTP * Module vendor m OTP * Module version 6.11 OTP * Antenna SKU X3 DT (ARM64) or ACPI (x86) In macOS, these firmwares are stored using filenames in this format under /usr/share/firmware/wifi: C-4378__s-B1/P-shikoku-X3_M-RASP_V-m__m-6.11.txt To prepare firmwares for Linux, we rename these to a scheme following the existing brcmfmac convention: brcmfmac<chip><lower(rev)>-pcie.apple,<platform>-<mod_type>-\ <mod_vendor>-<mod_version>-<antenna_sku>.txt The NVRAM uses all the components, while the firmware and CLM blob only use the chip/revision/platform/antenna_sku: brcmfmac<chip><lower(rev)>-pcie.apple,<platform>-<antenna_sku>.bin e.g. brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m-6.11-X3.txt brcm/brcmfmac4378b1-pcie.apple,shikoku-X3.bin In addition, since there are over 1000 files in total, many of which are symlinks or outright duplicates, we deduplicate and prune the firmware tree to reduce firmware filenames to fewer dimensions. For example, the shikoku platform (MacBook Air M1 2020) simplifies to just 4 files: brcm/brcmfmac4378b1-pcie.apple,shikoku.clm_blob brcm/brcmfmac4378b1-pcie.apple,shikoku.bin brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m.txt brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-u.txt This reduces the total file count to around 170, of which 75 are symlinks and 95 are regular files: 7 firmware blobs, 27 CLM blobs, and 61 NVRAM config files. We also slightly process NVRAM files to correct some formatting issues. To handle this, the driver must try the following path formats when looking for firmware files: brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m-6.11-X3.txt brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m-6.11.txt brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m.txt brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP.txt brcm/brcmfmac4378b1-pcie.apple,shikoku-X3.txt * brcm/brcmfmac4378b1-pcie.apple,shikoku.txt * Not relevant for NVRAM, only for firmware/CLM. The chip revision nominally comes from OTP on Apple platforms, but it can be mapped to the PCI revision number, so we ignore the OTP revision and continue to use the existing PCI revision mechanism to identify chip revisions, as the driver already does for other chips. Unfortunately, the mapping is not consistent between different chip types, so this has to be determined experimentally. Reviewed-by: -

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. Reviewed-by:

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. Reviewed-by:

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. Signed-off-by:

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). Then, add properties required for firmware selection and calibration on M1 machines. Reviewed-by:

Found by comparing with the vendor driver. Currently this affects only the RTL8192EU, which is the only gen2 chip with 2 TX paths supported by this driver. It's unclear what kind of effect the mistake had in practice, since I don't have any RTL8192EU devices to test it.

The range of calibration time of RX DCK is quite wide from ~40us to ~1300us by experiments, and probability is about 0.1% for the cases larger than 1000us.

We can call this in one of two ways: through mac80211, where we're already in an RCU read-side critical section, or from some other code in the driver where this pointer can only be NULL. In any case, we get a 'free' already protected pointer to the sta through info->control.sta, so we can use it on the stack without any further protection.
