[PATCH v2 0/3] Bluetooth: power-on QCA6390 correctly

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Patch 1 is just a typo fix as we're already touching this bindings. The
second patch adds more regulator defintions 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

[PATCH v2 2/3] dt-bindings: net: bluetooth: qualcomm: add regulators for QCA6390

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Add regulator properties for QCA6390 that are missing from the bindings
and enforce required properties for this model as well.

[PATCH v2 3/3] Bluetooth: qca: run the power-on/off sequence for QCA6390 too

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

The Bluetooth module on QCA6390 needs to be powered-on by enabling the
relevant regulators and driving the enable GPIO high. We can reuse the
power sequence for the WNC models if we add the list of required
regulators to the OF match data.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC. It might happen, that command when run on an older
kernel, gives you outdated entries. Therefore please be sure you base
your patches on recent Linux kernel.

You missed at least devicetree list (maybe more), so this won't be
tested by automated tooling. Performing review on untested code might be
a waste of time, thus I will skip this patch entirely till you follow
the process allowing the patch to be tested.

Please kindly resend and include all necessary To/Cc entries.

Best regards,
Krzysztof

Sorry, I just used the command I used last but this time there were
additional dt-bindings patches. Will resend it tomorrow.
