Subject: [PATCH] ARM: dts: imx6ul-pico-hobbit: Use WDOG_B pin reset
Date: Tue, 16 Aug 2016 22:46:42 -0300 [thread overview]
Message-ID: <1471398402-20559-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@nxp.com>
imx6ul-pico has WDOG1_B pin connected to the PMIC.
Pass the 'fsl,ext-reset-output' property so that the watchdog
can trigger a system POR reset via PMIC.
