[PATCH ath-next 0/3] wifi: ath12k: accept what newer QCN9274 firmware requests at boot

[Goran Sustek]

With QCN9274 firmware WLAN.WBE.1.6-01243 (the newest in
ath12k-firmware) the driver logs three warnings at every boot:

  ath12k_wifi7_pci 0000:06:00.0: memory type 10 not supported
  ath12k_wifi7_pci 0000:06:00.0: Invalid module id 2
  ath12k_wifi7_pci 0000:06:00.0: failed to parse tlv -22

The firmware is not at fault: it requests the AFC memory region
(QMI memory type 10) and advertises a direct buffer ring for CV
upload (module 2), both defined in Qualcomm's interface headers but
not yet known to the driver.

Patch 1 allocates the AFC region instead of answering with a NULL
address. Patch 2 makes the DMA ring capability parser skip unknown
module IDs instead of aborting the event, and fixes the zero-filled
entry a plain skip would leave. Patch 3 names modules 2 and 3.

The idea of patch 2 was posted earlier by Nazar Mokrynskyi:

Tested on a QCN9274 hw2.0 PCI board (single device, AP MLD on 5 GHz
and 2.4 GHz) with the series on top of v7.3.1: all three warnings are
gone, the device comes up with both links, and there is no firmware
crash, call trace or IOMMU fault.

  wifi: ath12k: allocate the AFC memory region requested by firmware
  wifi: ath12k: skip unknown direct buffer ring module IDs
  wifi: ath12k: name direct buffer ring modules 2 and 3
