SHDWC Shutdown Controller
required properties:
- compatible: Should be "atmel,<chip>-shdwc".
<chip> can be "at91sam9260", "at91sam9rl" or "at91sam9x5".
- reg: Should contain registers location and length
- clocks: phandle to input clock.
optional properties:
- atmel,wakeup-mode: String, operation mode of the wakeup mode.
Supported values are: "none", "high", "low", "any".
- atmel,wakeup-counter: Counter on Wake-up 0 (between 0x0 and 0xf).
optional at91sam9260 properties:
- atmel,wakeup-rtt-timer: boolean to enable Real-time Timer Wake-up.
optional at91sam9rl properties:
- atmel,wakeup-rtc-timer: boolean to enable Real-time Clock Wake-up.
- atmel,wakeup-rtt-timer: boolean to enable Real-time Timer Wake-up.
optional at91sam9x5 properties:
- atmel,wakeup-rtc-timer: boolean to enable Real-time Clock Wake-up.
Example:
shdwc@fffffd10 {
compatible = "atmel,at91sam9260-shdwc";
reg = <0xfffffd10 0x10>;
clocks = <&clk32k>;
};
