Editing: dpot-dac.txt
Bindings for DAC emulation using a digital potentiometer It is assumed that the dpot is used as a voltage divider between the current dpot wiper setting and the maximum resistance of the dpot. The divided voltage is provided by a vref regulator. .------. .-----------. | | | vref |--' .---. | regulator |--. | | '-----------' | | d | | | p | | | o | wiper | | t |<---------+ | | | | '---' dac output voltage | | '------+------------+ Required properties: - compatible: Should be "dpot-dac" - vref-supply: The regulator supplying the voltage divider. - io-channels: Channel node of the dpot to be used for the voltage division. - io-channel-names: Should be "dpot". Example: &i2c { dpot: mcp4651-503@28 { compatible = "microchip,mcp4651-503"; reg = <0x28>; #io-channel-cells = <1>; }; }; dac { compatible = "dpot-dac"; vref-supply = <®_3v3>; io-channels = <&dpot 0>; io-channel-names = "dpot"; };
