You still keep developing it on wrong, old kernel (or not using get_maintainers.pl, but this one seems too obvious so I assumed wrong kernel). > > Signed-off-by: Jan Kiszka <jan.kiszka@xxxxxxxxxxx> > --- > .../bindings/soc/ti/ti,am654-pvu.yaml | 51 +++++++++++++++++++ > 1 file changed, 51 insertions(+) > create mode 100644 Documentation/devicetree/bindings/soc/ti/ti,am654-pvu.yaml > > diff --git a/Documentation/devicetree/bindings/soc/ti/ti,am654-pvu.yaml b/Documentation/devicetree/bindings/soc/ti/ti,am654-pvu.yaml > new file mode 100644 > index 000000000000..fd0f86fa27b0 > --- /dev/null > +++ b/Documentation/devicetree/bindings/soc/ti/ti,am654-pvu.yaml > @@ -0,0 +1,51 @@ > +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) > +# Copyright (c) Siemens AG, 2024 > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/soc/ti/ti,am654-pvu.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: TI AM654 Peripheral Virtualization Unit > + > +maintainers: > + - Jan Kiszka <jan.kiszka@xxxxxxxxxxx> > + > +properties: > + compatible: > + enum: > + - ti,am654-pvu > + > + reg: > + minItems: 2 maxItems instead. > + > + reg-names: > + items: > + - const: cfg > + - const: tlbif > + > + interrupts: > + items: > + - description: fault interrupt > + > + interrupt-names: > + items: > + - const: pvu > + > +required: > + - compatible > + - reg > + - interrupts > + - interrupt-names > + > +additionalProperties: false > + > +examples: > + - | > + ti-pvu@30f80000 { Node names should be generic. See also an explanation and list of examples (not exhaustive) in DT specification: https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation for sure "ti" is not generic. pvu is the device name.
