I am trying to define a few GPIO in the device tree. Somehow it seems not
to work.
I added the following to the &am33xx_pinmux node:
status_pins: status_pins {
pinctrl-single,pins = <
0x044 (PIN_OUTPUT_PULLUP | MUX_MODE7) /* Run LED/gpio1_17/sys
49 */
0x180 (PIN_OUTPUT_PULLUP | MUX_MODE7) /* Error
LED/gpio0_14/sys 14 */
0x184 (PIN_OUTPUT_PULLUP | MUX_MODE7) /* LAN LED/gpio0_15/sys
15 */
>;
};
Created a custom node as follows:
status {
compatible = "bone-pinmux-helper";
pinctrl-names = "default";
pinctrl-0 = <&status_pins>;
status = "okay";
};
After exporting gpio49 and checking the direction it is defined as input,
while I expect output.
Also tried to add &status_pins to the pinctrl of uart2 but it seems to have
no effect.
What am I overlooking here ?
Thanks for any help
