[PATCH v4 0/2] fsl,irqsteer: power-domain support

[Alexander Stein]

Hi,

this is a new spin on the irqsteer bindings adding power-dmain support.
Thanks for the previous feedback. This v4 adds imx8mp specific compatible
to support power-domain.

Best regards,
Alexander

Changes in v4:
* Added imx8mp-specific compatible
* Restrict power-domains on non-imx8mp or non-imx8qxp SoCs
* Added patch for imx8mp.dtsi adjusting compatible

  dt-bindings: interrupt-controller: fsl,irqsteer: Add imx8mp/imx8qxp
    support
  arm64: dts: imx8mp: Add imx8mp-specific irqsteer compatible

[PATCH v4 1/2] dt-bindings: interrupt-controller: fsl,irqsteer: Add imx8mp/imx8qxp support

[Alexander Stein]

Some SoC like i.MX8MP or i.MX8QXP use a power-domain for this IP. Add
SoC-specific compatibles, which also requires a power-domain.

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

yamllint warnings/errors:
./Documentation/devicetree/bindings/interrupt-controller/fsl,irqsteer.yaml:85:17: [warning] wrong indentation: expected 14 but found 16 (indentation)

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240527083402.30895-2-alexander.stein@ew.tq-group.com

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 v4 2/2] arm64: dts: imx8mp: Add imx8mp-specific irqsteer compatible

[Alexander Stein]

i.MX8MP irqsteer has power-domain support, so use a dedicated compatible.
