Add devicetree binding documentation for twl4030-madcI'm happy with this, but it needs the usual sign off form a device tree
analog digital converter.

+* TWL4030 Monitoring Analog to Digital Converter (MADC)
+
+The MADC subsystem in the TWL4030 consists of a 10-bit ADC
+combined with a 16-input analog multiplexer.
+
+Required properties:
+ - compatible: Should contain "ti,twl4030-madc".
+ - interrupts: IRQ line for the MADC submodule.
+ - #io-channel-cells: Should be set to <1>.
+
+Optional properties:
+ - ti,system-uses-second-madc-irq: boolean, set if the second madc irq register
+ should be used, which is intended to be used
+ by Co-Processors (e.g. a modem).
+
+Example:
+
+&twl {
+ madc {
+ compatible = "ti,twl4030-madc";
+ interrupts = <3>;
+ #io-channel-cells = <1>;
+ };
+};
