Subject: [PATCH 0/2] Fixes for the SAMA5D2/SAMA5D4 watchdog
Date: Fri, 14 Sep 2018 12:13:37 +0200 [thread overview]
Message-ID: <20180914101339.7382-1-romain.izard.pro@gmail.com> (raw)
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.
