* 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>;
};
};
