Subject: [PATCH 0/2] Fixes for the SAMA5D2/SAMA5D4 watchdog
Date:   Fri, 14 Sep 2018 12:13:37 +0200
Message-Id: <20180914101339.7382-1-romain.izard.pro@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A previous change of the sama5d4_wdt driver broke the device probing
with the device tree configuration described in existing DTS files,
when no value is set for the "timeout-sec" property.

Moreover, specifying any other value than 16 seconds for "timeout-sec"
leads to a watchdog reset immediately when opening the watchdog device.
Fix this by respecting hardware constraints added in recent versions of
the SAMA5D2 and SAMA5D4 datasheet.

Romain Izard (2):
  watchdog: sama5d4: fix timeout-sec usage
  watchdog: sama5d4: write the mode register in two steps
