Subject: [PATCH 0/6] Bluetooth: hci_qca: use the power sequencer for
 wcn7850

The following series extend the usage of the power sequencing subsystem
in the hci_qca driver.

The end goal is to convert the entire driver to be exclusively pwrseq-based
and simplify it in the process. However due to a large number of users we
need to be careful and consider every case separately.

Right now the only model that fully uses the power sequencer is QCA6390 on
the RB5 board. The next steps are enabling pwrseq for Bluetooth on sm8650
and the X13s laptop. To that end we need to make wcn7850 and wcn6855 aware
of the power sequencing but also keep backward compatibility with older
device trees.

This series contains changes to mainline DT bindings for wcn7850, some
refactoring of the hci_qca driver, making pwrseq the default for the two
models mentioned above and finally modifies the device-tree for sm8650-qrd
to correctly represent the way the Bluetooth module is powered.

I made the last patch part of this series as it has a run-time dependency
on previous changes in it and bluetooth support on the board will break
without them.
