This has been tested with firmware version 0xaa9a4e68. I am submitting as an RFC to hopefully get guidance from Realtek on submission of this firmware (or a later version) to the linux-firmware repository.

It's very similar, and uses some of the same constants, but has a different firmware. I assumed the firmware difference is enough to require it to be differentiated, but I wasn't sure. You are saying it does not? I just want to be clear. As always, thank you. > > Best regards, > Krzysztof > ^ permalink raw reply [flat|nested] 9+ messages in thread

If by "differentiated" you mean "incompatible", then depends: 1. You have firmware-name property to indicate the firmware to load and then you can use one compatible to bind and just load different firmware, 2. If device variant is autodectable, it's compatible. realtek,rtl8723ds-bt also was added to the driver uselessly... Best regards, Krzysztof ^ permalink raw reply [flat|nested] 9+ messages in thread

They are incompatible, but the driver should be able to autodetect each device as best I can tell. In fact all of the devices listed in the bindings should be autodetectable by the driver (again, as best I can tell). Honestly though that's assuming I'm using the correct firmware, which is why I have this tagged as an RFC. I'm really hoping to get Realtek's attention for them to chime in to confirm I'm using the most recent firmware and under what license/terms the firmware can be redistributed so that the firmware may be added to linux-firmware. Assuming everything is good though, I can resubmit V2 and instead of adding a new compatible just noting that the 8822CS and 8821CS use the same bindings.

They cannot use the same bindings. You always need specific compatible and this was not discussed here. What's discussed is to drop the driver change in of_device_id.
