acpi_dev_add_driver_gpios() makes it possible to set up mapping between
properties and ACPI GpioIo resources in a driver, so we can take index
parameter in acpi_find_gpio() into use with _DSD device properties now.
This index can be used to select a GPIO from a property with multiple
GPIOs:
Package () {
"data-gpios",
Package () {
\_SB.GPIO, 0, 0, 0,
\_SB.GPIO, 1, 0, 0,
\_SB.GPIO, 2, 0, 1,
}
}
In order to retrieve the last GPIO from a driver we can simply do:
desc = devm_gpiod_get_index(dev, "data", 2);
and so on.

Cool. :-)
Any objections anyone?
Looks good to me!

Since this looks like a bug fix, shouldn't this be squashed into the
relevant patch of the device-properties set?
