| Watchdog driver general info |
| |
| CONFIG_HW_WATCHDOG |
| This enables hw_watchdog_reset to be called during various loops, |
| including waiting for a character on a serial port. But it |
| does not also call hw_watchdog_init. Boards which want this |
| enabled must call this function in their board file. This split |
| is useful because some rom's enable the watchdog when downloading |
| new code, so it must be serviced, but the board would rather it |
| was off. And, it cannot always be turned off once on. |
| |
| CONFIG_WATCHDOG_TIMEOUT_MSECS |
| Can be used to change the timeout for i.mx31/35/5x/6x. |
| If not given, will default to maximum timeout. This would |
| be 128000 msec for i.mx31/35/5x/6x. |
| |
| CONFIG_AT91SAM9_WATCHDOG |
| Available for AT91SAM9 to service the watchdog. |
| |
| CONFIG_FTWDT010_WATCHDOG |
| Available for FTWDT010 to service the watchdog. |
| |
| CONFIG_FTWDT010_HW_TIMEOUT |
| Can be used to change the timeout for FTWDT010. |
| |
| CONFIG_IMX_WATCHDOG |
| Available for i.mx31/35/5x/6x to service the watchdog. This is not |
| automatically set because some boards (vision2) still need to define |
| their own hw_watchdog_reset routine. |
| TODO: vision2 is removed now, so perhaps this can be changed. |
| |
| CONFIG_XILINX_TB_WATCHDOG |
| Available for Xilinx Axi platforms to service timebase watchdog timer. |
| |
| CONFIG_BFIN_WATCHDOG |
| Available for bf5xx and bf6xx to service the watchdog. |
