Subject[PATCH] regulator: fixed: Use more standard GPIO binding
Date
The fixed regulator uses "gpio" (singularis) for the GPIO line
but the standard GPIO bindings recommend "gpios" (pluralis).

We have augmented the Linux kernel to handle both, so recommend
the best practice and deprecate the singularis variant.
