Resending with all maintainers in CC.

Patch 1 is just a typo fix as we're already touching this bindings. The
second patch adds more regulator definitions and enforces them for the
QCA6390 model. The final patch enables the power sequence for the BT
module of QCA6390 in the hci_qca driver.

v1 -> v2:
- squashed the two bluetooth patches into one
- changed the naming convention for the RFA regulators to follow the
  existing ones
- added dt-bindings patches

Bartosz Golaszewski (3):
  dt-bindings: net: bluetooth: qualcomm: fix a typo
  dt-bindings: net: bluetooth: qualcomm: add regulators for QCA6390
  Bluetooth: qca: run the power-on/off sequence for QCA6390 too

WLAN-specific regulators for PCIe are enabled anyway but the WLAN
enable GPIO is low and the relevant pin function is not even
configured. I can confirm Bluetooth is functional.

I too thought we'd need a common power-sequence here but Abel pointed
out that neither RB5 nor X13s require it, it's only needed in later
models.
