Here's V4 of the AC97/I2S ASoC patchset for early Alchemy
chips and their respective evaluation boards.
The patches are largely based on the old mips/au1x00.c driver which
AC97 Tested on a Db1500 development board; I2S untested since none
of the testboards I have actually have an I2S codec (just testpoints).
Changes since V3:
- dropped the hunk which removed the I2S constants from the au1000.h header
to avoid merge conflicts with other patches.
- use the context structure declared in psc.h. Follow-up patches for psc* code
depend on this.
Changes since V2:
- implemented changes after feedback from Lars-Peter Clausen:
* split patch 1 in two, one for the ASoC drivers, and a separate for
DB1000 machine code.
* get rid of automatic dma device registration
* tidied the I2S/AC97 sources
- mark sound/mips/au1x00.c as DEPRECATED instead of removing it outright.
Changes since V1:
- added untested I2S controller driver for completeness, removed the audio
defines from the au1000 header.
