Hi, The patches are to cater the need for non-ACPI system whereby a platform device has to be created in order to bind with Apollo Lake Pinctrl GPIO platform driver. The MMIO BAR is accessed over the Primary to Sideband bridge (P2SB). Since the BIOS prevents the P2SB device from being enumerated by the PCI subsystem, so we need to hide/unhide P2SB to lookup the P2SB BAR and pass the PCI BAR address to the gpio platform driver. All these three patches have dependencies on each other.
