1 Watchdog driver general info
4 This enables hw_watchdog_reset to be called during various loops,
5 including waiting for a character on a serial port. But it
6 does not also call hw_watchdog_init. Boards which want this
7 enabled must call this function in their board file. This split
8 is useful because some rom's enable the watchdog when downloading
9 new code, so it must be serviced, but the board would rather it
10 was off. And, it cannot always be turned off once on.
12 CONFIG_WATCHDOG_TIMEOUT_MSECS
13 Can be used to change the timeout for i.mx31/35/5x/6x.
14 If not given, will default to maximum timeout. This would
15 be 128000 msec for i.mx31/35/5x/6x.
18 Available for AT91SAM9 to service the watchdog.
21 Available for i.mx31/35/5x/6x to service the watchdog. This is not
22 automatically set because some boards (vision2) still need to define
23 their own hw_watchdog_reset routine.
24 TODO: vision2 is removed now, so perhaps this can be changed.
26 CONFIG_XILINX_TB_WATCHDOG
27 Available for Xilinx Axi platforms to service timebase watchdog timer.
