Subject: ARM: dts: imx6sx-sdb: Use WDOG_B pin reset
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8c4a18e232851dda93e3308c5d69595c18524c89;p=linux-beck.git

ARM: dts: imx6sx-sdb: Use WDOG_B pin reset

imx6sx-sdb 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.
