Subject: ARM: dts: imx6ul-kontron: Move watchdog from Kontron i.MX6UL/ULL board to SoM
From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>
commit 04a2c05179b732a4c097f0a9c701ef4c9a37e1e3 upstream.
The watchdog's WDOG_ANY signal is used to trigger a POR of the SoC,
if a soft reset is issued. As the SoM hardware connects the WDOG_ANY
and the POR signals, the watchdog node itself and the pin
configuration should be part of the common SoM devicetree.
Let's move it from the baseboard's devicetree to its proper place.
