drivers/watchdog: Add optional ASPEED device tree properties
Describe device tree optional properties: * aspeed,reset-type = "cpu|soc|system|none" One of three different, mutually exclusive, values "cpu" : ARM CPU reset on signal "soc" : 'System on chip' reset "system" : Full system reset The value can also be set to "none" which indicates that no reset of any kind is to be done via this watchdog. This assumes another watchdog on the chip is to take care of resets. * aspeed,external-signal - Generate external signal (WDT1 and WDT2 only) * aspeed,alt-boot - Boot from alternate block on signal Signed-off-by: Christopher Bostic <cbostic@linux.vnet.ibm.com> Acked-by: Rob Herring <robh@kernel.org> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
