Subject: ARM: dts: imx6ul-kontron: Change WDOG_ANY signal from push-pull to open-drain
From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>
commit d22a16cc92e04d053fd807ef3587e4f135e4206f upstream.
The WDOG_ANY signal is connected to the RESET_IN signal of the SoM
and baseboard. It is currently configured as push-pull, which means
that if some external device like a programmer wants to assert the
RESET_IN signal by pulling it to ground, it drives against the high
level WDOG_ANY output of the SoC.
To fix this we set the WDOG_ANY signal to open-drain configuration.
That way we make sure that the RESET_IN can be asserted by the
watchdog as well as by external devices.
