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.
