| H A D | gpiolib-of.c | 6a537d48 Wed Dec 27 09:37:44 CST 2017 Linus Walleij <linus.walleij@linaro.org> gpio: of: Support regulator nonstandard GPIO properties
Before it was clearly established that all GPIO properties in the
device tree shall be named "foo-gpios" (with the deprecated variant
"foo-gpio" for single lines) we unfortunately merged a few bindings
for regulators with random phandle names.
As we want to switch the GPIO regulator driver to using descriptors,
we need devm_gpiod_get() to return something reasonable when looking
up these in the device tree.
Put in a special #ifdef:ed kludge to do this special lookup only
for the regulator case and gets compiled out if we're not enabling
regulators. Supply a whitelist with properties we accept.
