The reason for these firmware-names should be added to the commit
message.

Since the platform uses the QCA6698 Bluetooth chip. While the QCA6698
shares the same IP core as the WCN6855, it has different RF components
and RAM sizes, requiring new firmware files. Use the firmware-name property
to specify the NVM and rampatch firmware to load.
Will add this to commit message.

And that patch depends on something else.
You make it very difficult to review and even more difficult to merge.

There is no such alias?

So every contributor here will add some random order...

Ah there is, found now added by Sayali Lokhande <quic_sayalil@quicinc.com>.
Anyway, organize your work in reasonable patchsets not 3 or more
one-patchers spread all over the mailing list.
