39       reset when a timeout occcurs.
41       Specifying 'cpu' will only reset the processor on a timeout event.
43       Specifying 'soc' will reset a configurable subset of the SoC's controllers
45       untouched. The set of SoC controllers to reset may be specified via the
46       aspeed,reset-mask property if the node has the aspeed,ast2500-wdt or
47       aspeed,ast2600-wdt compatible.
49       Specifying 'system' will reset all controllers on a timeout event, as if
52       Specifying 'none' will cause the timeout event to have no reset effect.
53       Another watchdog engine on the chip must be used for chip reset operations.

73   aspeed,ext-push-pull:
76       If aspeed,external-signal is specified in the node, set the external
77       signal pin's drive type to push-pull. If aspeed,ext-push-pull is not
78       specified then the pin is configured as open-drain.
80   aspeed,ext-active-high:
83       If both aspeed,external-signal and aspeed,ext-push-pull are specified in
84       the node, set the pulse polarity to active-high. If aspeed,ext-active-high
85       is not specified then the pin is configured as active-low.
