/*
 * Walter-specific application-level DT additions.
 *
 * Walter has a MOSFET on GPIO0 (active-low) that gates the on-board 3.3V
 * output rail. The rail is OFF at reset; any external sensor wired to V3.3
 * is unpowered until something asserts this GPIO. Modeled as a regulator-fixed
 * with regulator-boot-on so Zephyr's regulator framework enables it during
 * kernel init, before driver init runs.
