Subject: [PATCH v4 0/2] add a new driver to support SAMA5D4 watchdog timer
Date: Thu, 6 Aug 2015 12:59:28 +0800 [thread overview]
Message-ID: <1438837170-4518-1-git-send-email-wenyou.yang@atmel.com> (raw)
Hello,
Because the watchdog WDT_MR register can be written more than once,
its work mechanism is different from the at91sam9260 watchdog driver.
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 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.
