[PATCH 00/12] Bluetooth: dt-bindings: qualcomm: Split binding

[Krzysztof Kozlowski]

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,qca6390-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.

What's more it messes up old (pre-PMU) and new (post-PMU) description in
one place adding to the total mess.

Best regards,
Krzysztof

[PATCH 01/12] Bluetooth: MAINTAINERS: Orphan Qualcomm hci_qca

[Krzysztof Kozlowski]

There are no maintainers of Qualcomm hci_qca Bluetooth driver, so make
it explicit that driver was orphaned and no one cares to keep it
maintained.  That's also indication for future removal from the Linux
kernel.

Actually, I added that entry so that the arm-msm list can get Cc'ed on
patches. The fact it didn't use to, caused some regressions. I have
done some work on it, so I can take it over as maintainer.

Ahaha, nice :)

It also points out that drivers do not have a maintainer.

Sure, I'll send separate patch for that replacing this one. Shall I add
you to the bindings as well? All or only some?

I'm more familiar with the C part but sure, why not.

[PATCH 02/12] dt-bindings: bluetooth: qcom,qca2066-bt: Split to separate schema

[Krzysztof Kozlowski]

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split common part and
qcom,qca2066-bt to separate bindings, so each schema will be easier to
read/maintain and list only relevant properties.

The existing bindings do not mention interrupts, but
am335x-sancloud-bbe-extended-wifi.dts already defines such.  This issue
is not being fixed here.

Existing binding also did not mention any supplies (which do exist as
confirmed in datasheet) and Linux driver does not ask for any, thus keep
this state unchanged.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

[PATCH 03/12] dt-bindings: bluetooth: qcom,qca9377-bt: Split to separate schema

[Krzysztof Kozlowski]

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,qca9377-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.

Existing binding has incomplete and incorrect list of supplies (e.g.
there is no VDD_XO) and Linux driver does not ask for any, thus keep
this state unchanged.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20251028-dt-bindings-qcom-bluetooth-v1-3-524a978e3cda@linaro.org

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

[PATCH 04/12] dt-bindings: bluetooth: qcom,qca6390-bt: Split to separate schema

[Krzysztof Kozlowski]

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,qca6390-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.

[PATCH 06/12] dt-bindings: bluetooth: qcom,wcn3990-bt: Split to separate schema

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,wcn3990-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.

This binding is very similar to qcom,wcn3950-bt, however devices have
additional VDD_CH1 supply.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Lexical error: Documentation/devicetree/bindings/net/bluetooth/qualcomm-bluetooth.example.dts:24.42-58 Unexpected 'GPIO_ACTIVE_HIGH'
Lexical error: Documentation/devicetree/bindings/net/bluetooth/qualcomm-bluetooth.example.dts:25.42-58 Unexpected 'GPIO_ACTIVE_HIGH'

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20251028-dt-bindings-qcom-bluetooth-v1-6-524a978e3cda@linaro.org

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

[PATCH 07/12] dt-bindings: bluetooth: qcom,wcn6750-bt: Split to separate schema

[Krzysztof Kozlowski]

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,wcn6750-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.

[PATCH 08/12] dt-bindings: bluetooth: qcom,wcn6750-bt: Deprecate old supplies

[Krzysztof Kozlowski]

Commit cca4fe34979a ("dt-bindings: bluetooth: Utilize PMU abstraction
for WCN6750") changed the binding to new description with a Power
Management Unit (PMU), thus certain power-controller properties are
considered deprecated and are part of that PMUs binding.

Deprecate them to mark clearly that new PMU-based approach is preferred.

[PATCH 12/12] dt-bindings: bluetooth: qcom,wcn7850-bt: Deprecate old supplies

[Krzysztof Kozlowski]

Commit bd3f305886ad ("dt-bindings: bluetooth: qualcomm: describe the
inputs from PMU for wcn7850") changed the binding to new description
with a Power Management Unit (PMU), thus certain power-controller
properties are considered deprecated and are part of that PMUs binding.

Deprecate them to mark clearly that new PMU-based approach is preferred.
