regmap: Supply ranges to the sync operations

2012-02-24T14:52:40+00:00

In order to allow us to support partial sync operations add minimum and
maximum register arguments to the sync operation and update the rbtree
and lzo caches to use this new information. The LZO implementation is
obviously not good, we could exit the iteration earlier, but there may
be room for more wide reaching optimisation there.

regmap: Don't use bitfields for booleans

2012-02-06T19:24:35+00:00

This was a cut'n'paste from some older code.

Since we're about to add debugfs support don't do the obvious thing and
use bool, use u32 instead (which debugfs has been using since time
immemorial).

regmap: Support register patch sets

2012-01-23T14:01:18+00:00

Device manufacturers frequently provide register sequences, usually not
fully documented, to be run at startup in order to provide better defaults
for devices (for example, improving performance in the light of silicon
evaluation). Support such updates by allowing drivers to register update
sets with the core. These updates will be written to the device immediately
and will also be rewritten when the cache is synced.

The assumption is that the reason for resyncing the cache will always be
that the device has been powered off. If this turns out to not be the case
then a separate operation can be provided.

Currently the implementation only allows a single set of updates to be
specified for a device, this could be extended in future.

regmap: Add support for padding between register and address

2012-01-20T12:15:39+00:00

Some devices, especially those with high speed control interfaces, require
padding between the register and the data. Support this in the regmap API
by providing a pad_bits configuration parameter.

Only devices with integer byte counts are supported.

regmap: Remove indexed cache type

2011-11-20T20:56:34+00:00

There should be no situation where it offers any advantage over rbtree
and there are no current users so remove the code for simplicity.

regmap: Move initialization of regcache related fields to regcache_init

2011-11-16T17:34:53+00:00

Move the initialization regcache related fields of the regmap struct to
regcache_init. This allows us to keep regmap and regcache code better
separated.

regmap: Track if the register cache is dirty and suppress unneeded syncs

2011-11-08T11:38:15+00:00

Allow drivers to optimise out the register cache sync if they didn't need
to do one. If the hardware is desynced from the register cache (by power
loss for example) then the driver should call regcache_mark_dirty() to
let the core know about this.
