[PATCH ath-current 0/2] wifi: ath11k: add usecase firmware handling based on device compatible

[Miaoqing Pan]

The 'firmware-name' property was introduced to allow end-users and
integrators to select use-case-specific firmware for the WCN6855.
But 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 use-case-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.

[PATCH ath-current 1/2] wifi: ath11k: add usecase firmware handling based on device compatible

[Miaoqing Pan]

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.

For details on usecase specific firmware, see:
https://lore.kernel.org/all/20250522013444.1301330-3-miaoqing.pan@oss.qualcomm.com/.

Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-04685-QCAHSPSWPL_V1_V2_SILICONZ_IOE-1

[PATCH ath-current 2/2] dt-bindings: net: wireless: ath11k-pci: deprecate 'firmware-name' property

[Miaoqing Pan]

The firmware-name property was introduced to allow end-users and
integrators to select usecase specific firmware for the WCN6855.
However, specifying firmware for an M.2 WLAN module in the Device
Tree is not appropriate. Instead, this functionality will be handled
within the ath11k driver.

The driver patch completely removes support for this, so is this really
considered deprecated? Or should this actually be considered obsolete and
completely removed?

Do any DTS files actually reference this?

First, yes, still NAK.

Second, that patch faked Rob's tag, so it is unacceptable!

You are correct — since the driver has already removed all support for
`firmware-name`, marking it as `deprecated` is misleading. The proper
status should be `obsolete`, and the binding should reflect that this
property is no longer supported. Regarding DTS usage: no upstream Device 
Tree files currently reference `firmware-name`.
