Subject: ARM: dts: imx7s-warp: Use WDOG_B pin reset
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a7311c0c9a338d18f4a6d21dfad34c66053c9225;p=linux-beck.git

ARM: dts: imx7s-warp: Use WDOG_B pin reset

imx7s-warpd 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 the PMIC.
