|
RAVE SP watchdog device is a "MFD cell" device corresponding to
|
watchdog functionality of RAVE Supervisory Processor. It is expected
|
that its Device Tree node is specified as a child of the node
|
corresponding to the parent RAVE SP device (as documented in
|
Documentation/devicetree/bindings/mfd/zii,rave-sp.txt)
|
|
Required properties:
|
|
- compatible: Depending on wire protocol implemented by RAVE SP
|
firmware, should be one of:
|
- "zii,rave-sp-watchdog"
|
- "zii,rave-sp-watchdog-legacy"
|
|
Optional properties:
|
|
- wdt-timeout: Two byte nvmem cell specified as per
|
Documentation/devicetree/bindings/nvmem/nvmem.txt
|
|
Example:
|
|
rave-sp {
|
compatible = "zii,rave-sp-rdu1";
|
current-speed = <38400>;
|
|
eeprom {
|
wdt_timeout: wdt-timeout@8E {
|
reg = <0x8E 2>;
|
};
|
};
|
|
watchdog {
|
compatible = "zii,rave-sp-watchdog";
|
nvmem-cells = <&wdt_timeout>;
|
nvmem-cell-names = "wdt-timeout";
|
};
|
}
