Hello, I have prepared some patches that debug and modify the behaviour of extant S3C I2S support towards managing I2Sv4 controllers as well. Overall pic... For now the 'new' I2Sv4 CPU driver(s3c64xx-i2s-v4.c) is almost a copy of s3c64xx-i2s.c The driver will evolve as support for more features is added. Minor quirks in otherwise similar controllers are handled by defining a new field(feature) in 'struct s3c_i2sv2_info' that is meant to contain 1-bit flags for absence/presence of such quirks. The header with I2S register map and bit definitions has been copied to where the drivers are(sound/soc/s3c24xx/) since the header has nothing usable for platform code. Also, it will help avoid need for co-ordination between ASoC and S3C ARCH trees. For now, the header regs-s3c2412-iis.h is left intact but rendered useless by making ASoC drivers include the newly copied version of it (sound/soc/s3c24xx/regs-i2s-v2.h) Later the header could be dropped by patches to S3C PLAT tree. The patches apply against 'for-2.6.35' of http://www.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git Regards.
