|  | * 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>; | 
|  | }; | 
|  | }; |
