Subject: [PATCH] hwmon: (max6650.c) Add devicetree support documentation
Date: Tue, 16 Aug 2016 09:23:10 +0200	[thread overview]
Message-ID: <1471332190-14638-1-git-send-email-mike.looijmans@topic.nl> (raw)

This adds the devicetree binding documentation for the max6650 fan
controller.

+Bindings for MAX6651 and MAX6650 I2C fan controllers
+
+Reference:
+[1]	https://datasheets.maximintegrated.com/en/ds/MAX6650-MAX6651.pdf
+
+Required properties:
+- compatible : One of "maxim,max6650" or "maxim,max6651"
+- reg        : I2C address, one of 0x1b, 0x1f, 0x4b, 0x48.
+
+Optional properties, default is to retain the chip's current setting:
+- maxim,fan-microvolt : The supply voltage of the fan, sets the ADC range to
+			either 5V or 12V. Max value 13500000.
+- maxim,fan-prescale  : Pre-scaling value, as per datasheet [1]. Lower values
+			allow more fine-grained control of slower fans.
+			Valid: 1, 2, 4, 8, 16.
+
+Example:
+	fan-max6650: max6650@1b {
+		reg = <0x1b>;
+		compatible = "maxim,max6650";
+		maxim,fan-microvolt = <12000000>;
+		maxim,fan-prescale = <4>;
