[PATCH 1/4] dt-bindings: iio: light: sharp,gp2ap020a00f: Add supplies

[Linus Walleij <linusw@kernel.org>]

The GP2AP020A00F needs a core supply as well as power for its infrared
LED. Its I2C and interrupt pull-up resistors may also be supplied from
a separately controlled rail.

Describe the core supply as vdd-supply and the pull-up supply as
vio-supply. Keep both properties optional to preserve compatibility
with existing device trees that only describe vled-supply.
