It might happen, that command when run on an older kernel, gives you outdated entries.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. > --- > .../bindings/hwmon/ti,j721e-esm.yaml | 55 +++++++++++++++++++ > 1 file changed, 55 insertions(+) > create mode 100644 Documentation/devicetree/bindings/hwmon/ti,j721e-esm.yaml > > diff --git a/Documentation/devicetree/bindings/hwmon/ti,j721e-esm.yaml b/Documentation/devicetree/bindings/hwmon/ti,j721e-esm.yaml > new file mode 100644 > index 000000000000..7b23ac7cb3ba > --- /dev/null > +++ b/Documentation/devicetree/bindings/hwmon/ti,j721e-esm.yaml > @@ -0,0 +1,55 @@ > +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) > +# Copyright (C) 2022 Texas Instruments Incorporated > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/hwmon/ti,j721e-esm.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: Texas Instruments K3 ESM > + > +maintainers: > + - Neha Malcom Francis <n-francis@xxxxxx> > + > +description: > + The ESM (Error Signaling Module) is an IP block on TI K3 devices > + that allows handling of safety events somewhat similar to what interrupt > + controller would do.
