Hi Stewart,
Take this with a grain of salt. I have never used the ioexpander ... took a
quick look after seeing your email.
You need to populate ioexpander_ops_s within your board specific files.
IOEXP_WRITEPIN is the "virtual function" that calls your board specific
write_pin function (which call

Hello,
I have a processor board with GPIO ports which I would like to use to
control such things as relays and PSU enable pins.
Do I need to write a GPIO driver? There is an I/O expander driver. Is
the I/O expander driver specific to expanders or can it be used for GPIO
control?
Kind regar
