# NOTE: The driver supports "regulator-fixed-sync" as a specializing
# variant when it's known that the GPIO state change operations are
# isr-ok and not sleep, and both startup and off-on delays are zero.
# This bypasses the asynchronous onoff manager which optimizes both time
# and memory use.
#
# To enable this use both:
# compatible = "regulator-fixed-sync", "regulator-fixed";
#
compatible: "regulator-fixed"

GPIO to use to enable/disable the regulator.
Unlike the gpio property in the Linux bindings this array must
provide the GPIO polarity and open-drain status in the phandle
selector. The Linux enable-active-high and gpio-open-drain
properties are not valid for Zephyr devicetree files.
