2009-08-11ASoC: fix I2C build errorsRandy Dunlap
Fix soc build errors when I2C is built as a loadable module: (.text+0x5d26b): undefined reference to `i2c_master_send' soc-cache.c:(.text+0x5d32d): undefined reference to `i2c_transfer' Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-08-03ASoC: Factor out 7 bit register 9 bit data SPI writeMark Brown
This converts all the Wolfson drivers using this format (the only devices that do) except WM8753 to use it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-08-03ASoC: Factor out I2C 8 bit address 16 bit data I/OMark Brown
As part of this refactoring the type of the CODEC hw_read operation is changed to match the regular read operation. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-08-03ASoC: Add I/O control bus information to factored out cache setupMark Brown
While writes tend to be able to use a fairly bus independant format to do the writes reads are all bus specific. To allow us to factor out this code include the bus type as a parameter when setting up the cache. Initially just use this to factor out hw_write_t for I2C.

2009-07-05ASoC: Begin to factor out register cache I/O functionsMark Brown
A lot of CODECs share the same register data formats and therefore replicate the code to manage access to and caching of the register map. In order to reduce code duplication centralised versions of this code will be introduced with drivers able to configure the use of the common code by calling the new snd_soc_codec_set_cache_io() API call during startup. As an initial user the 7 bit address/9 bit data format used by many Wolfson devices is supported for write only CODECs and the drivers with straightforward register cache implementations are converted to use it.
