There's a bug in the gpio-export code. :)
But I'm rewriting it to use the following syntax:
gpio-export,name = "mario";
gpio-export,flags = "out_init_high", "active_low", "changeable";
gpio-export,gpios = <&gpio0 11 1>;
Which will support the following flags (had to add GPIOF_ACTIVE_LOW):
static struct of_gpio_flag of_gpio_flags[] = {
{ "in", GPIOF_DIR_IN },
{ "out_init_low", GPIOF_OUT_INIT_LOW },
{ "out_init_high", GPIOF_OUT_INIT_HIGH },
{ "open_drain", GPIOF_OPEN_DRAIN },
{ "open_source", GPIOF_OPEN_SOURCE },
{ "active_low", GPIOF_ACTIVE_LOW },
{ "changeable", GPIOF_EXPORT_CHANGEABLE },
{ /* sentinel */ }
};
