Hello *!

I have an Intel-based mainboard with build-in gpios that I'd like to use.
However, I cannot get the kernel (5.16) to recognise the chip (NXP PCA9554).
To my understanding, this should be supported with the gpio_pca953x kernel
module. Upon loading this, the kernel reports no device or chip found, so all
further actions via /sys/class/gpio/ or gpioinfo return nothing.

Any ideas what I might be missing here?


Regards,
Gerrit
