[PATCH v2 05/11] ACPI: property: Allow direct graph endpoint references

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



By using device and further data node references, allow direct references
to endpoints. These are of form

	Package() { \DEV, "portX", "endpointY" }

where X is the number of the port and Y is the number of the endpoint.
