-Bindings for ADC envelope detector using a DAC and a comparator
-
-The DAC is used to find the peak level of an alternating voltage input
-signal by a binary search using the output of a comparator wired to
-an interrupt pin. Like so:
-                          _
-                         | \
-    input +------>-------|+ \
-                         |   \
-           .-------.     |    }---.
-           |       |     |   /    |
-           |    dac|-->--|- /     |
-           |       |     |_/      |
-           |       |              |
-           |       |              |
-           |    irq|------<-------'
-           |       |
-           '-------'
-
-Required properties:
-- compatible: Should be "axentia,tse850-envelope-detector"
-- io-channels: Channel node of the dac to be used for comparator input.
-- io-channel-names: Should be "dac".
-- interrupt specification for one client interrupt,
-  see ../../interrupt-controller/interrupts.txt for details.
-- interrupt-names: Should be "comp".

-Example:
-
-	&i2c {
-		dpot: mcp4651-104@28 {
-			compatible = "microchip,mcp4651-104";
-			reg = <0x28>;
-			#io-channel-cells = <1>;
-		};
-	};
-
-	dac: dac {
-		compatible = "dpot-dac";
-		vref-supply = <&reg_3v3>;
-		io-channels = <&dpot 0>;
-		io-channel-names = "dpot";
-		#io-channel-cells = <1>;
-	};
-
-	envelope-detector {
-		compatible = "axentia,tse850-envelope-detector";
-		io-channels = <&dac 0>;
-		io-channel-names = "dac";
-
-		interrupt-parent = <&gpio>;
-		interrupts = <3 IRQ_TYPE_EDGE_FALLING>;
-		interrupt-names = "comp";
-	};
