Kernel 4.1 without cap ( am335x-bone-common-no-capemgr.dtsi ) and GPIO


I’m using the beaglebone black without the capemanager ( am335x-bone-common-no-capemgr.dtsi ) .

My problem is to figure out how to use the gpio without the cape manager.

how do you declare in the device tree a gpio ?

gpio_node {
compatible = “bone-pinmux-helper”;
pinctrl-names = “default”;
pinctrl-0 = <&gpio_micka>;
status = “okay”;

I don’t see which driver can handle the “bone-pinmux-helper”

Any idea ?
