      1 Watchdog driver general info
      2 
      3 CONFIG_HW_WATCHDOG
      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.
     11 
     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.
     16 
     17 CONFIG_AT91SAM9_WATCHDOG
     18 	Available for AT91SAM9 to service the watchdog.
     19 
     20 CONFIG_FTWDT010_WATCHDOG
     21 	Available for FTWDT010 to service the watchdog.
     22 
     23 CONFIG_FTWDT010_HW_TIMEOUT
     24 	Can be used to change the timeout for FTWDT010.
     25 
     26 CONFIG_IMX_WATCHDOG
     27 	Available for i.mx31/35/5x/6x to service the watchdog. This is not
     28 	automatically set because some boards (vision2) still need to define
     29 	their own hw_watchdog_reset routine.
     30 	TODO: vision2 is removed now, so perhaps this can be changed.
     31 
     32 CONFIG_XILINX_TB_WATCHDOG
     33 	Available for Xilinx Axi platforms to service timebase watchdog timer.
