From 34339c858ca1ed955cfe6f78a656882e66310920 Mon Sep 17 00:00:00 2001 From: Eliav Farber Date: Thu, 8 Sep 2022 15:24:44 +0000 Subject: [PATCH] dt-bindings: hwmon: (mr75203) add "moortec,ts-series" property Add optional "moortec,ts-series" property to define the temperature equation and coefficients that shall be used to convert the digital output to value in milli-Celsius. Supported series: 5 (default) and 6. Series 5: T = G + H * (n / cal5 - 0.5) + J * F Where: G = 60, H = 200, cal5 = 4094, J = -0.1, F = frequency clock in MHz Series 6: T = G + H * (n / cal5 - 0.5) Where: G = 57.4, H = 249.4, cal5 = 4096 Signed-off-by: Eliav Farber Reviewed-by: Rob Herring Link: https://lore.kernel.org/r/20220908152449.35457-17-farbere@amazon.com Signed-off-by: Guenter Roeck --- .../devicetree/bindings/hwmon/moortec,mr75203.yaml | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/Documentation/devicetree/bindings/hwmon/moortec,mr75203.yaml b/Documentation/devicetree/bindings/hwmon/moortec,mr75203.yaml index d6b03a6d7043..df849517464e 100644 --- a/Documentation/devicetree/bindings/hwmon/moortec,mr75203.yaml +++ b/Documentation/devicetree/bindings/hwmon/moortec,mr75203.yaml @@ -91,6 +91,15 @@ properties: Each channel should not appear more than once. $ref: /schemas/types.yaml#/definitions/uint8-array + moortec,ts-series: + description: + Definition of the temperature equation and coefficients that shall be + used to convert the digital output to value in milli-Celsius. + minimum: 5 + maximum: 6 + default: 5 + $ref: /schemas/types.yaml#/definitions/uint32 + required: - compatible - reg
