ACPICA: ACPI 6.2: Add support for PinGroupConfig() resource
ACPICA commit 08b83591c0db751769d61fa889f4f50f575aeffb PinGroupConfig() is analogous to PinGroupFunction() but instead of mode (muxing), it is used to apply specific fine-grained configuration to a set of referenced pins. The format of this new resource is: PinGroupConfig (Shared/Exclusive, PinConfigType, PinConfigValue, ResourceSource, ResourceSourceIndex, ResourceSourceLabel, ResourceUsage, DescriptorName, VendorData) The PinConfigType/PinConfigValue are the same used by PinConfig() resource. Here also the combination of ResourceSource and ResourceSourceLabel is used to specify the PinGroup() this resource refers to.
