Subject: [PATCH 1/4] AC97 wm9713 support
Date: Fri, 25 Feb 2005 14:23:17 +0000 [thread overview]
Message-ID: <1109341397.30473.671.camel@cearnarfon> (raw)
[-- Attachment #1: Type: text/plain, Size: 1076 bytes --]
This patch is against ac97_codec.c and includes parts of Takashi's AC97
low power codec patch posted to lkml on Jan 4th 2005. It also includes
better enumerated mixer type support.
Apologies for the size of this patch. This was the minimum changes
required to get audio in/out of the codec.
Changes:-
o Added WM9713/WM9714 to codec ID table
o Removed snd_ac97_[info|get|put]_mux().
o Added snd_ac97_[info|get|put]_enum_single() for single channel enums
o Added snd_ac97_[info|get|put]_enum_double() for double channel enums
o Moved AC97_ENUM_DOUBLE macro to ac97_local.h
o Moved AC97_DOUBLE macro to ac97_local.h
o Changed existing std enums to use new enum macros
o Added the following AC97 flags to be checked at setup:-
AC97_HAS_NO_PC_BEEP, AC97_HAS_NO_PHONE, AC97_HAS_NO_CD,
AC97_HAS_NO_VIDEO, AC97_HAS_NO_REC_GAIN.
o Added look_for_codec_id() to match given id with the codec id.
o Added register reset protection for codecs that need it.
