Intel CNVi moves key elements of Wi-Fi and Bluetooth Technology into
Intel processors. As a result, their driver may have to be revised
across processor generations.


This depends on a few changes set to address all issues on supporting:
* PCI [8086:7af0] Subsystem [8086:4090] (AX211)
  * WiFi: iwlwifi-so-a0-gf-a0-*
  * BT: intel/ibt-1040-0041.* (ADL-S)
  * BT: intel/ibt-0040-0041.* (ADL-P)
* PCI [8086:7af0] Subsystem [8086:4070] (AX201)
  * WiFi: iwlwifi-so-a0-hr-b0-*
  * BT: intel/ibt-1040-4150.*
* PCI [8086:7af0] Subsystem [8086:0aaa] (9462)
  * WiFi: iwlwifi-so-a0-jf-b0-*
  * BT: intel/ibt-1040-1020.*

AX201 wifi firmware for ADL platforms will be available with FW
API >= 64, so a patchset "iwlwifi: bump FW API to 64 for AX devices"
will be required. Depending fixes are pulled as well.

For reset of them, 3 additional commits for iwlwifi, also in mainline
now, are required.

The last patch for 9462 Bluetooth is still under review at the time of
writing. This is the only patch that is not yet in unstable.

[Test Case]

Install these CRF on ADL-S/ADL-P platforms and check if WiFi/Bluetooth
is working.

[Where problems could occur]

While this is a new generation, we may have common issues like power
consumption, network throughput, suspend/resume issues.

[Other Info]

Intel is to release the corresponding firmware blobs next week. These
are verified with pre-released firmware.
