Do you need it to support negative values?
Patches welcome!

Maybe I misunderstand, but pinconf_generic_parse_dt_config()
looks at  pctldev->desc->custom_params and
pctldev->desc->num_custom_params found in
struct pinctrl_desc in
include/linux/pinctrl/pinctrl.h

$ git grep custom_params drivers/pinctrl/
gives you a list of all drivers using this.

Yours,
