It doesn't work.
I missed something. But what it is?
I use
FreeBSD-12.1-STABLE-arm-armv7-GENERICSD-20191212-r355610.img
> grep gpioiic /boot/loader.conf
gpioiic_load="YES"
fdt_overlays="sun8i-h3-sid,sun8i-h3-ths,sun8i-h3-opp,sun8i-h3-i2c0,sun8i-h3-gpioiic"
I did make /boot/dtb/overlays/sun8i-h3-gpioiic.dtbo from
> cat sun8i-h3-gpioiic.dtso
/dts-v1/;
/plugin/;
/ {
compatible = "allwinner,sun8i-h3";
};
&{/soc/pinctrl@1c20800} {
gpioiic@0 {
compatible = "allwinner,sun8i-h3,gpioiic";
scl = <0>; /* GPIO pin 00 (PA0) */
sda = <2>; /* GPIO pin 02 (PA2) */
};
};
I see gpioiic in ofwdump:
> ofwdump -a | grep -B 1 gpio
Node 0x1b7c: pinctrl@1c20800
Node 0x1c74: gpioiic@0
But I do not see in /dev and devinfo
:-(
