Use the modern (PMU) bindings. Also please add WiFi.
The modern PMU support for the WCN39xx family is currently not available in
hci qca driver, that is why we have defined the regulators directly within
the Bluetooth node.

Of course it is, see commit 9f168e4de5fd ("Bluetooth: qca: enable pwrseq
support for WCN39xx devices").

Thanks for pointing out. I see that pwrseq support for WCN39xx was indeed added in commit 9f168e4de5fd. I'll update the patches to use the modern PMU bindings.
