Split the ath12k driver into two kernel modules:
- ath12k.ko for shared logic across multiple targets
- ath12k_wifi7.ko for Wi-Fi 7 specific configuration and routines
The common module (ath12k.ko) must be loaded prior to any device-specific
module, as the latter depends on exported symbols from the former.
As part of this restructuring, Wi-Fi 7 specific files are moved into a
dedicated `wifi7/` directory and built as a separate module. Common
symbols are exported accordingly, with further adjustments planned
in upcoming patches to support architecture-dependent separation.
This modularization improves maintainability and scalability by enabling
clean separation of hardware-specific logic from the shared driver core.

Consider a multi-link AP configuration:
MLD vif (MAC addr: aa:bb)
|-- 2.4 GHz link (BSSID: aa:bb)
|-- 5 GHz link (BSSID: cc:dd)
For AP vdevs, ath12k creates a DP peer using the arvif's BSSID and stores
it in dp_hw->dp_peers_list. During scan operations, the driver assigns an
arvif to the scan vdev and uses the vif's MAC address as its BSSID. In
the above scenario, the scan vdev MAC address (aa:bb) matches the BSSID
of the 2.4 GHz AP link, causing a duplicate entry in dp_hw->dp_peers_list
and leading to scan vdev creation failure.
Failure in vif bringup sequence:
1. Create AP vdev for 2.4 GHz link:
- Assign arvif with BSSID = aa:bb and link_id = 0.
- Create DP peer with address aa:bb and add to dp_hw->dp_peers_list.
2. Create scan vdev for 5 GHz link:
- Assign arvif with BSSID = aa:bb (same as vif MAC address) and
link_id = 15.
- Attempt to create another DP peer with address aa:bb.
- Operation fails because aa:bb already exists in dp_hw->dp_peers_list,
resulting in duplicate entry conflict.
3. Delete scan vdev for 5 GHz link.
4. Create AP vdev for 5 GHz link.
Since DP peer is not needed for scan operations, identify scan vdev using
arvif->link_id >= IEEE80211_MLD_MAX_NUM_LINKS and skip DP peer creation
and deletion.

pci_set_drvdata() is called twice in ath12k_pci_probe() with the same pointer. Remove the earlier call so drvdata is set after ath12k_base and ath12k_pci initialization is complete. Having two calls might suggest that drvdata needs to be set early for some reason, even though it is not used until after the 'ab' struct ath12k_base is fully populated. Even though exact placement is not critical, keeping a single pci_set_drvdata() at the end of the initialization makes it clearer that drvdata points to a fully initialized structure and avoids confusion for future changes.

Rename the first one to ath12k_wifi7_hal_reo_init_cmd_ring_tlv64() to
better reflect what it is doing. There will be a 32 bit variant when
QCC2072 support is in place.
For the last ones, remove TLV length assumption and offload TLV encoding

can register its own handler hence can do the work accordingly.

For single pdev device like WCN7850/QCC2072, preferred_hw_mode is initialized to WMI_HOST_HW_MODE_SINGLE. Later when firmware sends supported modes to host, each mode is compared with the initial one and if the priority of the new mode is higher, update the parameter and store mode capability. For WCN7850, this does not result in issue, as one of the supported mode indeed has a higher priority. However the only available mode of QCC2072 at this stage is WMI_HOST_HW_MODE_SINGLE, which fails the comparison, hence mode capability is not stored. Subsequently driver initialization fails. Fix it by accepting a mode with the same priority.

For single pdev device, 320 MHz bandwidth support is reported only in capability of WMI_HOST_HW_MODE_SINGLE mode, hence commit d4e244c ("wifi: ath12k: enable 320 MHz bandwidth for 6 GHz band in EHT PHY capability for WCN7850") relaxed the condition check in ath12k_wmi_tlv_mac_phy_caps_ext() to allow SINGLE mode getting parsed in ath12k_wmi_tlv_mac_phy_caps_ext_parse(). Since SINGLE mode is not assumed to be preferred, the function returns unconditionally after parsing 320 MHz support. This works for WCN7850 because it prefers another mode indeed, while it breaks QCC2072 since it prefers SINGLE mode. Due to the unconditional return, the subsequent EHT parsing is skipped. Consequently EHT related features are disabled. Refactor it by moving 320 MHz parsing to ath12k_wmi_tlv_mac_phy_caps_ext(), before the mode checking. This makes the code more straightforward, and work for both WCN7850 and QCC2072.

Add hardware parameters for QCC2072, these parameters are directly taken from WCN7850, with exceptions to hardware name, revision, firmware directory, iova_mask and RFKILL parameter set. Compared to WCN7850, QCC2072 doesn't require aligned IOVA when transmitting packets, hence iova_mask is set to zero. Besides, WCN7850 has a dedicated GPIO for RFKILL purpose, however QCC2072 has it coupled with WLAN_EN pin. For QCC2072, host is not allowed to send any RFKILL configuration info to firmware, or firmware crashes. Hence those parameters are all cleared to skip configuring command.

Due to HAL descriptors, QCC2027 has different offsets of MPDU start tag and MSDU end tag, compared with other chips. Hence add new hardware ops structure for QCC2072.

As far as REO CMD ring is concerned, there are two differences between
QCC2072 and the existing chips:
For the first, the TLV header of ring descriptor for QCC2072 is 32 bits
while 64 bits for existing chips.
For the second, QCC2072 has different hal_reo_get_queue_stats,
hal_reo_flush_cache and hal_reo_update_rx_queue structures. Take
hal_reo_get_queue_stats as an example:
QCC2072:
struct hal_reo_get_queue_stats_qcc2072 {
struct hal_reo_cmd_hdr cmd;
[...]
__le32 rsvd0[6];
} __packed;
QCN9274/WCN7850:
struct hal_reo_get_queue_stats {
struct hal_reo_cmd_hdr cmd;
[...]
__le32 rsvd0[6];
__le32 tlv64_pad;
} __packed;
Note there is no tlv64_pad at the end for QCC2072, but all other
former fields share the same layout.
These make different ring entry size, so that parameter has to be updated
with respect to existing chips. This is done in the newly introduced
ath12k_hal_srng_create_config_qcc2072() function, which first creates all
ring configs by utilizing ath12k_hal_srng_create_config_wcn7850() and then
updates the individual field.
Besides, the REO command TLV encoding also need to be corrected because of
the different TLV bits. This is done by introducing a 32 bit variant for
each of the existing 64 bit callback.
Note the hal_reo_get_queue_stats_qcc2072 structure is introduced for the
purpose of calculating ring entry size. Existing hal_reo_get_queue_stats
structure gets used elsewhere even for QCC2072. This is working because
the only difference is the tlv64_pad field that is located at the end and
not getting used, hence can be ignored.

For QCC2072 below REO status descriptors are different compared with
QCN9274/WCN7850:
hal_reo_get_queue_stats_status
hal_reo_flush_queue_status
hal_reo_flush_cache_status
hal_reo_unblock_cache_status
hal_reo_flush_timeout_list_status
hal_reo_desc_thresh_reached_status
Take hal_reo_get_queue_stats_status as an example:
QCC2072:
struct hal_reo_get_queue_stats_status_qcc2072 {
__le32 tlv32_padding;
struct hal_reo_get_queue_stats_status status;
} __packed;
QCN9274/WCN7850:
struct hal_reo_get_queue_stats_status;
Besides, QCC2072 has a 32 bits TLV header while QCN9274/WCN7850 has 64.
This means that there is no difference between these 3 devices in layout
of actual fields, because they all start after a 8 bytes offset
QCC2072:
{
struct hal_tlv_hdr tlv;
__le32 tlv32_padding;
struct hal_reo_get_queue_stats_status status;
}
QCN9274/WCN7850:
{
struct hal_tlv_64_hdr tlv;
struct hal_reo_get_queue_stats_status status;
}
Therefore current implementation luckily works for QCC2072 as well.
However it leads to misunderstanding, which should be avoided.
So add individual REO status ring handling for QCC2072.

QCC2072 is a PCI based device that is very much like WCN7850, the major difference is that QCC2072 has only one phy hence does not support DBS. With previous patches handling such similarity and difference, it is now ready to finally enable supporting this device. Add QCC2072's ID to the PCI device ID table, to allow it getting probed hence enable support. Also populate some necessary parameters when probing.

… compatible For M.2 WLAN chips, there is no suitable DTS node to specify the firmware-name property. In addition, assigning firmware for the M.2 PCIe interface causes chips that do not use usecase specific firmware to fail. Therefore, abandoning the approach of specifying firmware in DTS. As an alternative, propose a static lookup table mapping device compatible to firmware names. Currently, only WCN6855 HW2.1 requires this. However, support for the firmware-name property is retained to keep the ABI backwards compatible.

Currently, the FBC image is a non-standard ELF file that contains a single
ELF header, followed by segments for SBL, and WLAN FW. However, TME-L
(Trust Management Engine Lite) supported devices (eg. QCC2072) requires
separate ELF headers for SBL and WLAN FW segments due to TME-L image
authentication requirement.
Current image format contains two sections in a single binary:
- First 512KB: ELF header + SBL segments
- Remaining: WLAN FW segments
The TME-L supported image format contains two sections with two elf
headers in a single binary:
- First 512KB: First ELF header + SBL segments
- Remaining: Second ELF header + WLAN FW segments
Download behavior:
- Legacy: 1. First 512KB via BHI (ELF header + SBL)
2. Full image via BHIe
- TME-L: 1. First 512KB via BHI (First ELF header + SBL)
2. Remaining via BHIe (Second ELF header + WLAN FW segments)
Add standard_elf_image flag to mhi_controller_config to indicate TME-L
supported image format. When set, MHI skips the first 512KB during WLAN FW
download over BHIe as it is loaded in BHI phase.
