[PATCH v9 RESEND 0/3] watchdog: at91sam9_wdt: add device tree support

[Fabio Porcedda]

Hi all,

This patchset is for adding device tree support to the
at91sam9_wdt driver.

The "timeout-sec" binding is added by another patchset already sent:
[PATCH v4 0/8] watchdog: dt: add support for the timeout-sec dt property

Changes:
v9:
 - rebased over v3.7-rc1
v8:
 - add __initconst to at91_wdt_dt_ids
v7:
 - split the patchset
 - remove timeout binding
v6:
 - add watchdog core proprty timeout binding
 - add as example to the orion_wdt driver the new timeout binding
v5:
 - split dts commit in two, one for socs and one for boards.
v4:
 - use "atmel,at91sam9260-wdt" as compatible
v3:
 - add heartbeat option
 - default disabled for all the soc, enable only for evk-pro3 board
 - add at91sam9263 and at91sam9g45 soc
v2:
 - add missing to and cc addresses

Based on v3.7-rc5

Thanks, best regards,
