[PATCH 1/2] ARM: dts: imx7d-pico: Add watchdog support

[Fabio Estevam]

imx7d-pico has the WDOG1_B pin connected to the PMIC, so add the
wdog1 node and use the 'fsl,ext-reset-output' property to
properly describe it.

[PATCH 2/2] ARM: dts: imx7d-pico: Pass 'no-1-8-v' property to the eMMC

[Fabio Estevam]

Currently the following eMMC error is seen:

mmc1: mmc_select_hs200 failed, error -74

On imx7d-pico the eMMC VCCQ is fixed at 3.15V, so pass the 'no-1-8-v'
property to properly describe that 1.8V operation is not possible.

Maybe you forgot to push them to your tree?

Hmm, it's been on imx/dt for quite a few days, and for-next needs to be
updated though.
