Message-Id: <20220222223610.23098-1-linux@roeck-us.net> Date: Tue, 22 Feb 2022 14:36:09 -0800 From: Guenter Roeck <linux@...ck-us.net> To: linux-hwmon@...r.kernel.org Cc: Agathe Porte <agathe.porte@...ia.com>, Jean Delvare <jdelvare@...e.com>, Rob Herring <robh+dt@...nel.org>, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org, Krzysztof Adamski <krzysztof.adamski@...ia.com>, Guenter Roeck <linux@...ck-us.net> Subject: [PATCH v7 1/2] dt-bindings: hwmon: add tmp464.yaml From: Agathe Porte <agathe.porte@...ia.com> Add basic description of the tmp464 driver DT bindings. Signed-off-by: Agathe Porte <agathe.porte@...ia.com> Cc: Krzysztof Adamski <krzysztof.adamski@...ia.com> Signed-off-by: Guenter Roeck <linux@...ck-us.net> --- v7: - No change v6: - Model ti,n-factor as int32 instead of int8. v5: - Dropped ti,n-factor from channel@0 example. Added additional channel to examples to show positive ti,n-factor property. v4: - No changes v3: - Addedd support for TMP468. - Changed number of channels from 0..3 (which was wrong anyway) to 0..8. - Changed value range for ti,n-factor to int8, with an example for a negative value. - Added myself as driver maintainer. .../devicetree/bindings/hwmon/ti,tmp464.yaml | 114 ++++++++++++++++++ MAINTAINERS | 7 ++ 2 files changed, 121 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/ti,tmp464.yaml diff --git a/Documentation/devicetree/bindings/hwmon/ti,tmp464.yaml b/Documentation/devicetree/bindings/hwmon/ti,tmp464.yaml new file mode 100644 index 000000000000..801ca9ba7d34 --- /dev/null +++ b/Documentation/devicetree/bindings/hwmon/ti,tmp464.yaml @@ -0,0 +1,114 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/hwmon/ti,tmp464.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: TMP464 and TMP468 temperature sensors + +maintainers: + - Agathe Porte <agathe.porte@...ia.com> + +description: | + ±0.0625°C Remote and Local temperature sensor + https://www.ti.com/lit/ds/symlink/tmp464.pdf + https://www.ti.com/lit/ds/symlink/tmp468.pdf + +properties: + compatible: + enum: + - ti,tmp464 + - ti,tmp468 + + reg: + maxItems: 1 + + '#address-cells': + const: 1 + + '#size-cells': + const: 0 + +required: + - compatible + - reg + +additionalProperties: false + +patternProperties: + "^channel@([0-8])$": + type: object + description: | + Represents channels of the device and their specific configuration. + + properties: + reg: + description: | + The channel number. 0 is local channel, 1-8 are remote channels. + items: + minimum: 0 + maximum: 8 + + label: + description: | + A descriptive name for this channel, like "ambient" or "psu". + + ti,n-factor: + description: | + The value (two's complement) to be programmed in the channel specific N correction register. + For remote channels only. + $ref: /schemas/types.yaml#/definitions/int32 + items: + minimum: -128 + maximum: 127 + + required: + - reg + + additionalProperties: false + +examples: + - | + i2c { + #address-cells = <1>; + #size-cells = <0>; + + sensor@4b { + compatible = "ti,tmp464"; + reg = <0x4b>; + }; + }; + - | + i2c { + #address-cells = <1>; + #size-cells = <0>; + + sensor@4b { + compatible = "ti,tmp464"; + reg = <0x4b>; + #address-cells = <1>; + #size-cells = <0>; + + channel@0 { + reg = <0x0>; + label = "local"; + }; + + channel@1 { + reg = <0x1>; + ti,n-factor = <(-10)>; + label = "external"; + }; + + channel@2 { + reg = <0x2>; + ti,n-factor = <0x10>; + label = "somelabel"; + }; + + channel@3 { + reg = <0x3>; + status = "disabled"; + }; + }; + }; diff --git a/MAINTAINERS b/MAINTAINERS index fca970a46e77..f51bc7c7e439 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -19489,6 +19489,13 @@ S: Maintained F: Documentation/hwmon/tmp401.rst F: drivers/hwmon/tmp401.c +TMP464 HARDWARE MONITOR DRIVER +M: Agathe Porte <agathe.porte@...ia.com> +M: Guenter Roeck <linux@...ck-us.net> +L: linux-hwmon@...r.kernel.org +S: Maintained +F: Documentation/devicetree/bindings/hwmon/ti,tmp464.yaml + TMP513 HARDWARE MONITOR DRIVER M: Eric Tremblay <etremblay@...tech-controls.com> L: linux-hwmon@...r.kernel.org -- 2.35.1
