Hi,
I have a problem with the ports on the A35, the ports on the M33 work.
In the dts:
gpio_export {
compatible = "gpio-export";
#size-cells = <0>;
SIO0_INIT_OUT {
gpio-export,name = "SIO0_INIT_OUT";
gpio-export,output = <0>;
gpios = <&gpiof 14 0>;
};
SIO1_INIT_OUT {
gpio-export,name = "SIO1_INIT_OUT";
gpio-export,output = <0>;
gpios = <&gpiof 21 0>;
};
};
and
&iomuxc1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_hog>;
…
pinctrl_hog: hoggrp {
fsl,pins = <
MX8ULP_PAD_PTF12__PTF12 0x3
MX8ULP_PAD_PTF13__PTF13 0x3
MX8ULP_PAD_PTF14__PTF14 0x3
MX8ULP_PAD_PTF21__PTF21 0x3
>;
};
…
But on command line I get:
root@imx8ulp-microgea:~# cat /sys/kernel/debug/gpio
gpiochip0: GPIOs 0-31, parent: platform/gpio@0, imx-rpmsg-gpio-0:

gpiochip6: GPIOs 508-511, parent: usb/1-1.1:1.0, ftdi-cbus, can sleep:
The GPIOs are inside gpiochip4, PTFxx should be inside gpiochip5, what goes wrong?
Thanks in advance, Tom
