I added the following to the dts:
[EMAIL PROTECTED] {
compatible = "linux,gpio-led";
linux,name = "green";
gpios = <&GPIO1 31>;
};
[EMAIL PROTECTED] {
compatible = "linux,gpio-led";
linux,name = "red";
gpios = <&GPIO1 30>;
};
I then map the gpio base as follows (I removed the if checks just to
make things short and sweet):
np = of_find_compatible_node(NULL, NULL, "linux,gpio-led");
gpios = of_get_property(np, "gpios", &lenp);
of_node_put(np);
np = of_find_node_by_phandle(gpios[0]);
gpio_base = of_iomap(np, 0);
of_node_put(np);
Comments?
Cheers,
Sean
