I will send V2 with following changes

1) Dt binding related to changes for adding optional property " gpio-reserved-ranges" on renesas binding documentation
2) SoC Dtsi with  " gpio-ranges = <&pfc 0 96 30>"
3) SoC Dtsi with" gpio-reserved-ranges = <17 10>" which defines unused gpios
4) Handle unused gpios in
       a) gpio_rcar_request
       b) gpio_rcar_set_multiple
       c)  gpio_rcar_resume

Regards,
Biju
