* 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>;
|
|
};
|
|
};
