different than what?

Also typo configurations.

Where are clocks?

Where are supplies?

Interrupt? No, it cannot be interrupt. This can be only enable pin and
then description is redundant. Look at other bindings.

Looks like matching QCA2066, except missing clocks, or like other QCA
devices with proper supplies.

I don't believe that Bluetooth device works without power.

No firmware?
