Plural, please, like in the previous version, cfr.
Documentation/devicetree/bindings/gpio/gpio.txt:
"GPIO properties should be named "[<name>-]gpios", with <name> being the purpose
of this GPIO for the device. While a non-existent <name> is considered valid
for compatibility reasons (resolving to the "gpios" property), it is
not allowed
for new bindings. Also, GPIO properties named "[<name>-]gpio" are valid and old
bindings use it, but are only supported for compatibility reasons and
should not
be used for newer bindings since it has been deprecated."
