1Zodiac Inflight Innovations RAVE Supervisory Processor Watchdog Bindings
2
3RAVE SP watchdog device is a "MFD cell" device corresponding to
4watchdog functionality of RAVE Supervisory Processor. It is expected
5that its Device Tree node is specified as a child of the node
6corresponding to the parent RAVE SP device (as documented in
7Documentation/devicetree/bindings/mfd/zii,rave-sp.txt)
8
9Required properties:
10
11- compatible: Depending on wire protocol implemented by RAVE SP
12  firmware, should be one of:
13	- "zii,rave-sp-watchdog"
14	- "zii,rave-sp-watchdog-legacy"
15
16Optional properties:
17
18- wdt-timeout:	Two byte nvmem cell specified as per
19		Documentation/devicetree/bindings/nvmem/nvmem.txt
20
21Example:
22
23	rave-sp {
24		compatible = "zii,rave-sp-rdu1";
25		current-speed = <38400>;
26
27		eeprom {
28			wdt_timeout: wdt-timeout@8E {
29				reg = <0x8E 2>;
30			};
31		};
32
33		watchdog {
34			compatible = "zii,rave-sp-watchdog";
35			nvmem-cells = <&wdt_timeout>;
36			nvmem-cell-names = "wdt-timeout";
37		};
38	}
