Subject: [PATCH 1/3] iio: adc: ltc2496: provide device tree binding document
Date: Mon, 11 Nov 2019 22:40:23 +0100 [thread overview]
Message-ID: <20191111214025.18310-1-u.kleine-koenig@pengutronix.de> (raw)
The ADC only requires the standard stuff for spi devices and a reference
voltage.

+Required properties:
+ - compatible: Must be "lltc,ltc2496"
+ - vref-supply: The regulator supply for ADC reference voltage
+ - further properties required for spi device nodes according to
+ Documentation/devicetree/bindings/spi/spi-controller.yaml
+
+Example:
+ ltc2497: adc@76 {
+ compatible = "lltc,ltc2496";
+ reg = <0>;
+ vref-supply = <<c249x_reg>;
+ spi-max-frequency = <2000000>;
