commit 1dcc6dd56926cc662e4e82d4b207f3c927de1545 Author: Nico Huber nico.huber@secunet.com Date: Thu May 23 18:13:23 2013 +0200
WIP: Start ACPI framework for PnP (super i/o) devices
I'm trying to make writing ACPI code for super i/o devices more comfortable.
pnp.asl hosts some general cpp macros.
The other four files are to be included in dsdt trees. They are controlled by cpp macros which should be defined/undefined before inclusion.
Work was inspired by Christoph Grentz' ACPI code for the W83627HF.
