Hi Simon,
I just submitted a new version of the patch, actually, when I tried to
use the GPIO on the header I saw a typo in the code.
To test it, you have to define these nodes in the device tree (should be
there by default or not?):
soc_gpio_s5_0@0 {
gpio-offset = <0x80 0>;
pad-offset = <0x1d0>;
mode-gpio;
output-value = <0>;
direction = <PIN_OUTPUT>;
};
soc_gpio_s5_1@0 {
gpio-offset = <0x80 1>;
pad-offset = <0x210>;
mode-gpio;
output-value = <0>;
direction = <PIN_OUTPUT>;
};
soc_gpio_s5_2@0 {
gpio-offset = <0x80 2>;
pad-offset = <0x1e0>;
mode-gpio;
output-value = <0>;
direction = <PIN_OUTPUT>;
};
And after, you can use the GPIO commands:
=> gpio set E0
gpio: pin E0 (gpio 128) value is 1
=> gpio clear E0
gpio: pin E0 (gpio 128) value is 0
=> gpio set E2
gpio: pin E2 (gpio 130) value is 1
=> gpio clear E2
gpio: pin E2 (gpio 130) value is 0
E0 E1 and E2 correspond to the GPIO0 1 and 2.
Regards,
Gabriel

Hi Gabriel,
I have two patches in patchwork:
http://patchwork.ozlabs.org/patch/471146/
http://patchwork.ozlabs.org/patch/471147/
Are they the correct ones? Also do you know how to use the gpio
command to toggle a bin on the Minnowboard MAX header? I'd like to try
that.
Regards,
Simon
