regmap: Add the LZO cache support This patch adds support for LZO compression when storing the register cache. For a typical device whose register map would normally occupy 25kB or 50kB by using the LZO compression technique, one can get down to ~5-7kB. There might be a performance penalty associated with each individual read/write due to decompressing/compressing the underlying cache, however that should not be noticeable. These memory benefits depend on whether the target architecture can get rid of the memory occupied by the original register defaults cache which is marked as __devinitconst. Nevertheless there will be some memory gain even if the target architecture can't get rid of the original register map, this should be around ~30-32kB instead of 50kB.

regmap: Provide register map dump via debugfs Copy over the read parts of the ASoC debugfs implementation into regmap, allowing users to see what the register values the device has are at runtime. The implementation, especially the support for seeking, is mostly due to Dimitris Papastamos' work in ASoC. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
