Subject: Reforming S3C I2S towards supporting I2Sv4
Date: Wed, 10 Mar 2010 16:48:55 +0900 [thread overview]
Message-ID: <1268207335-9947-1-git-send-email-jassi.brar@samsung.com> (raw)
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.
