The pin group for the gpio line must have the corresponding pinconf properties: PIN_CONFIG_BIAS_PULL_UP requires "pinctrl-single,bias-pullup" PIN_CONFIG_BIAS_PULL_DOWN requires "pinctrl-single,bias-pulldown" This is necessary for pcs_pinconf_set() to find the requested bias parameter in the PIN_MAP_TYPE_CONFIGS_GROUP pinctrl map.
