I will be rebasing that tree once rc1 is out in a few weeks time so in the meantime I will only push this out as testing for 0-day to take a look at it and see if we missed anything, Thanks, Jonathan > --- > Changes for v7: > - none > Changes for v6: > - none > Changes for v5: > - remove "bindings" from subject > - change unevaluatedProperties to additionalProperties > Changes for v4: > - use descriptive names for open/short circuit interrupts > - remove vdd regulator description > - remove unused import > - use generic sensor name in example > - don't use literal style for doc description > Changes for v3: > - Added dt-bindings > --- > .../iio/temperature/microchip,mcp9600.yaml | 70 +++++++++++++++++++ > 1 file changed, 70 insertions(+) > create mode 100644 Documentation/devicetree/bindings/iio/temperature/microchip,mcp9600.yaml > > diff --git a/Documentation/devicetree/bindings/iio/temperature/microchip,mcp9600.yaml b/Documentation/devicetree/bindings/iio/temperature/microchip,mcp9600.yaml > new file mode 100644 > index 000000000000..d2cafa38a544 > --- /dev/null > +++ b/Documentation/devicetree/bindings/iio/temperature/microchip,mcp9600.yaml > @@ -0,0 +1,70 @@ > +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/iio/temperature/microchip,mcp9600.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: Microchip MCP9600 thermocouple EMF converter > + > +maintainers: > + - Andrew Hepp <andrew.hepp@ahepp.dev> > + > +description: > + https://ww1.microchip.com/downloads/en/DeviceDoc/MCP960X-Data-Sheet-20005426.pdf > + > +properties: > + compatible: > + const: microchip,mcp9600 > + > + reg: > + maxItems: 1 > + > + interrupts: > + minItems: 1 > + maxItems: 6 > + > + interrupt-names: > + minItems: 1 > + maxItems: 6 > + items: > + enum: > + - open-circuit > + - short-circuit > + - alert1 > + - alert2 > + - alert3 > + - alert4 > + > + thermocouple-type: > + $ref: /schemas/types.yaml#/definitions/uint32 > + description: > + Type of thermocouple (THERMOCOUPLE_TYPE_K if omitted). > + Use defines in dt-bindings/iio/temperature/thermocouple.h. > + Supported types are B, E, J, K, N, R, S, T. > + > + vdd-supply: true > + > +required: > + - compatible > + - reg > + > +additionalProperties: false > + > +examples: > + - | > + #include <dt-bindings/iio/temperature/thermocouple.h> > + #include <dt-bindings/interrupt-controller/irq.h> > + i2c { > + #address-cells = <1>; > + #size-cells = <0>; > + > + temperature-sensor@60 { > + compatible = "microchip,mcp9600"; > + reg = <0x60>; > + interrupt-parent = <&gpio>; > + interrupts = <25 IRQ_TYPE_EDGE_RISING>; > + interrupt-names = "open-circuit"; > + thermocouple-type = <THERMOCOUPLE_TYPE_K>; > + vdd-supply = <&vdd>; > + }; > + };
