There will be two drivers available. The first driver under the hpe,gxp-gpio binding will provide GPIO information for the VUHC, CSM, and FN2 host interfaces. The second driver under the hpe,gxp-gpio-pl will provide GPIO information from the CPLD interface. The main difference and need for two separate bindings is they have different interrupt parents. The other is hpe,gxp-gpio is a combination of physical and virtual GPIOs where as hpe,gxp-gpio-pl are all physical GPIOs from the CPLD.
