Delta TN48M CPLD is used as a GPIO expander for the SFP GPIOs. It is a mix of input only and output only pins. Since there is no logical GPIO numbering arbitrary one is used along dt-bindings to make it humanly readable.
Can gpio/gpio-regmap.c be used here? See gpio/gpio-sl28cpld.c for an example. -michael
