[PATCH v4 0/1] Bluetooth: btqca: Add WCN6855 firmware priority selection feature

[PATCH v4 0/1] Bluetooth: btqca: Add WCN6855 firmware priority selection feature

[Shuai Zhang]

Update WCN6855 firmware to use the new FW file and added a fallback mechanism.

changed v4:
- Remove the hook function and use the existing mechanism to
  handle cases where the firmware cannot be found.
- Link to v3
  https://lore.kernel.org/all/20251117021645.712753-1-shuai.zhang@oss.qualcomm.com/

changed v2:
- Remove CC satble
- Update commit
- add test steps and log
- Link to v2
  https://lore.kernel.org/all/20251114081751.3940541-2-shuai.zhang@oss.qualcomm.com/

Changes v1:
- Add Fixes tag.
- Add comments in the commit and code to explain the reason for the changes.
- Link to v1

[PATCH v4 1/1] Bluetooth: btqca: Add WCN6855 firmware priority selection feature

[Shuai Zhang]

Historically, WCN685x and QCA2066 shared the same firmware files.
Now, changes are planned for the firmware that will make it incompatible
with QCA2066, so a new firmware name is required for WCN685x.

To code uniformity, move WCN7850 workaround to the caller.

Test Steps:
 - Boot device
 - Check the BTFW loading status via dmesg

Sanity pass and Test Log:
QCA Downloading qca/wcnhpbftfw21.tlv
Direct firmware load for qca/wcnhpbftfw21.tlv failed with error -2
QCA Downloading qca/hpbftfw21.tlv

Separate commit, please. It's not related to WCN685x firmware name
change.

If you scroll up, you will see that for WCN6750 at this point type
always is ELF_TYPE_PATCH, so the second part of the condition is
useless.

[PATCH v3 1/1] Bluetooth: btqca: Add WCN6855 firmware priority selection feature

Historically, WCN685x and QCA2066 shared the same firmware files.
Now, changes are planned for the firmware that will make it incompatible
with QCA2066, so a new firmware name is required for WCN685x.

Test Steps:
 - Boot device
 - Check the BTFW loading status via dmesg

Sanity pass and Test Log:

[PATCH v2 1/1] Bluetooth: btqca: Add WCN6855 firmware priority selection feature

[Shuai Zhang]

The prefix "wcn" corresponds to the WCN685x chip, while entries without
the "wcn" prefix correspond to the QCA2066 chip. There are some feature
differences between the two.

However, due to historical reasons, WCN685x chip has been using firmware
without the "wcn" prefix. The mapping between the chip and its
corresponding firmware has now been corrected.
