[yocto] GPIO configuration in imx6ull

[Vincent Prince]

Hi,

Are you aware of pin-muxing subject?

You can change GPIO settings in U-boot with gpio_* functions.
You can change them in DTS with gpio-edm driver from Wandboard kernel (
https://github.com/wandboard-org/linux/blob/4.1-2.0.x-imx/drivers/input/keyboard/gpio_edm.c
)
You can also change them in running Linux environment, i found this
resource quite complete

Best Regards,
Vincent
