ASoC: Remove rbtree register cache

2011-12-12T16:20:28+00:00

All users now use regmap directly so delete the ASoC version of the code.

ASoC: Remove LZO cache type

2011-11-10T13:08:09+00:00

There are no current users and new drivers ought to be using the regmap
API and its cache implementation directly so just delete the ASoC copy.

sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where needed

2011-10-31T23:31:22+00:00

These aren't modules, but they do make use of these macros, so
they will need export.h to get that definition.  Previously,
they got it via the implicit module.h inclusion.

ASoC: Fix register cache sync register_writable WARN_ONs

2011-08-31T08:46:16+00:00

Currently the condition for these WARN_ONs is reversed and they are placed
before the actual check whether we are going to write to that register. So if
the codec implements the register_writable callback we'll get a warning for each
writable register when syncing the register cache.

While we are at it change the check to use snd_soc_codec_writable_register
instead of open-coding it.

ASoC: soc-cache: Remove unneeded codec_drv pointer variable in snd_soc_lzo_get_blksize

2011-08-15T13:52:03+00:00

Since commit aea170a099793abcd0e6de46b947458073204241
"ASoC: soc-cache: Add reg_size as a member to snd_soc_codec",
the codec_drv pointer variable is not used in snd_soc_lzo_get_blksize.

ASoC: soc-cache: Remove unneeded codec_drv pointer variable in snd_soc_flat_cache_init

2011-08-15T13:52:02+00:00

Since commit d779fce5d79525d66269c8f6e430e1515d697f3d
"ASoC: soc-cache: Ensure flat compression uses a copy of the defaults cache",
the codec_drv pointer variable is not used any more.

ASoC: Move register I/O code into a separate file

2011-06-13T17:56:10+00:00

For clarity and to help ongoing refactoring in this area create a new file
to contain the physical I/O functions, separating them out from the cache
operations.

ASoC: Factor out redundant read() functions

2011-06-13T13:22:57+00:00

We've got a whole bunch of functions which just call straight through to
do_hw_read(). Simplify this situation by removing them and using hw_read()
directly.

ASoC: Suppress restore of default register values for rbtree cache sync

2011-06-08T14:24:36+00:00

Currently the rbtree code will write out the entire register map when
doing a cache sync which is wasteful and will slow things down. Check
to see if the value we're about to write is the default and don't bother
restoring it if it is, either the value will have been retained or the
device will have been reset and holds the value already.

We should really store the defaults in the nodes but this resolves the
immediate issue.
