ACPICA: ACPI 6.2: Add support for PinGroup() resource
ACPICA commit 7d928e3174fb19d7dc0066b03c30bea07c001563 ACPI 6.2 introduced a new resource that is used to declare set of pins belonging to a GPIO controller. This resource is referenced by new PinGroupFunction() and PinGroupConfig() resources using ResourceSource and ResourceLabel fields. The PinGroup() resource looks like this: PinGroup (ResourceLabel, ResourceUsage, DescriptorName, VendorData) {Pin List} This resource should be listed in _CRS under the GPIO/pincontroller device providing these pins.
