From 58fddc288b5cec192ad9eb9221da7ed14d974a27 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Thu, 8 Jan 2015 17:54:14 +0200 Subject: drm/i915: add component support Register a component to be used to interface with the snd_hda_intel driver. This is meant to replace the same interface that is currently based on module symbol lookup. v2: - change roles between the hda and i915 components (Daniel) - add the implementation to a new file (Jani) - use better namespacing (Jani) v3: - move the implementation to intel_audio.c (Daniel) - rename display_component to audio_component (Daniel) - add kerneldoc (Daniel) v4: - run forgotten git rm i915_component.c (Jani) Signed-off-by: Imre Deak Reviewed-by: Takashi Iwai Signed-off-by: Daniel Vetter --- include/drm/i915_component.h | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 include/drm/i915_component.h (limited to 'include/drm/i915_component.h') diff --git a/include/drm/i915_component.h b/include/drm/i915_component.h new file mode 100644 index 000000000000..3e2f22e5bf3c --- /dev/null +++ b/include/drm/i915_component.h @@ -0,0 +1,38 @@ +/* + * Copyright © 2014 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
