Please use GPIO_ACTIVE_HIGH label instead:
gpios = <&gpio4 8 GPIO_ACTIVE_HIGH>;

You are setting the LDB clock parent, but you don't use LDB in this
devicetree. You could simply remove this.

Node names should be generic:
m25p80: flash@0

This could be part of the pinctrl_ov2659 group as it provides the
clock for the camera.
Please try to keep in the hoggrp only the pins that cannot be
controlled by any other node.

Wouldn't it be better to enable wdog2 and disable wdog1 instead? wdog2
provides a POR, which is preferred.
