ACPICA: ACPI 6.2: Add support for PinGroupFunction() resource
ACPICA commit bd9a745749eac7137cd23085e6bdeb322de14ea2 PinGroupFunction() is a new resource introduced with ACPI 6.2. It is used with PinGroup() to configure specific mode for a set of pins exposed by a GPIO controller. The format of the resource is: PinGroupFunction (Shared/Exclusive, FunctionNumber, ResourceSource, ResourceSourceIndex, ResourceSourceLabel, ResourceUsage, DescriptorName, VendorData) The resource_source and ResourceSourceLabel fields are used to specify the PinGroup() resource referenced by PinGroupFunction(). Device (GPIO) { Name (_CRS, ResourceTemplate () { PinGroup ("group1") {2, 3} PinGroup ("group2") {4, 5} ... }) } Device (I2C) { Name (_CRS, ResourceTemplate () { PinGroupFunction (Exclusive, 6, "^GPIO", 0, "mygroup2") }) } In the above example the PinGroupFunction() references the second PinGroup() resource (using label "mygroup2" and configures pins 4 and 5 into mode 6.
