[PATCH v4 0/8] watchdog/at91sam9_wdt: Convert to use the new framework

Hi, All

The purpose of the patch series is to convert at91sam9_wdt to use the watchdog framework,

Because the Watchdog Mode Register(WDT_MR) which WDDIS bit to disable or disable the watchdog
can be written only once after reset. so if you want to use the watchdog in the kernel,
you must be sure the watchdog doesn't be disabled in the at91bootstrap.

It is tested on at91sam9m10g45ek both DT and non-DT support, at91sam9g25ek with DT support
by building Documentation/watchdog/src/watchdog-simple.c.

It is based on v3.8-rc6 + Arnd Bergmann's at91_wdt_dt_ids cannot be __init
+ Fabio Porcedda's add timeout-sec property binding

ChangeLog
v4:
- remove the patch: Use module_platform_driver().
- add tested on at91sam9m10g45ek both DT and non-DT support.
- rebase on v3.8-rc6

v3:
- The helper function 'watchdog_is_open' is moved to include/linux/watchdog.h
- Remove '__init' annotation from the function 'at91wdt_probe'
- Rebase on v3.8-rc2

v2:
- Remove the patches to add devive tree support which Fabio Porcedda has applied.
- Replace __raw_readl, __raw_writel with readl_relaxed, writel_relaxed.
- Rebase on v3.7-rc8.

Best Regards
