Open the device file to enable the watchdog hardware, close to disable it, and ping it from the user space directly to keep it alive. Changes from v4.0 1./ Fix interrupt register function flags argument. 2./ Replace the tabs after #define with spaces. Changes from v3.0 1./ Change the driver name to 'sama5d4_wdt' for more acceptable. 2./ Change the prefix of function name and struct name from 'atmel_' to 'sama5d4_', and others. Changes from v2.0 1./ Use a specific driver name, at91_sama5d4_wdt.c. 2./ Remove '-' at the end of macro name and unnecessary check. 3./ Use alphabetic order for include files.
