Signed-off-by: Ashish Yadav --- This patch introduces a YAML schema describing the required and optional properties for the XDP720 eFuse device node. It includes details on the compatible string, register mapping, and rimon-micro-ohms(RIMON). The RIMON resistance is installed between the Imon pin and the ground reference. --- .../bindings/hwmon/pmbus/infineon,xdp720.yaml | 52 +++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/pmbus/infineon,= xdp720.yaml diff --git a/Documentation/devicetree/bindings/hwmon/pmbus/infineon,xdp720.= yaml b/Documentation/devicetree/bindings/hwmon/pmbus/infineon,xdp720.yaml new file mode 100644 index 000000000000..09249a326eee --- /dev/null +++ b/Documentation/devicetree/bindings/hwmon/pmbus/infineon,xdp720.yaml @@ -0,0 +1,52 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- + +$id: http://devicetree.org/schemas/hwmon/pmbus/infineon,xdp720.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Infineon XDP720 Digital eFuse Controller + +maintainers: + - Ashish Yadav + +description: | + The XDP720 is an eFuse with integrated current sensor and digital + controller.
