ARM: dts: imx: ventana: Add ext watchdog reset
bc677ff42e81bbf78308a7b66cf7b63b0f5c26b0 adds a device-tree property to specify that an external watchdog reset is used to reset other portions of the board and not just the IMX6 SoC. This adds the property to the proper watchdog as well as the pinmux for the Gateworks Ventana boards that use this external watchdog reset to reset the PMIC which will reset all the PMIC power rails and not just a chip-level IMX6 reset. This helps to work around various system issues that can cause a hang when coming out of reset. Signed-off-by: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
