The registers for AD193X are defined as 0x800-0x810 for spi which uses
16_8 mode, for i2c to support AD1937, we will use 8_8 mode, only the low
byte of 0x800-0x810 is valid. The patch will not destory other codecs,
but make soc cache interface more useful.Signed-off-by: Barry Song

Add a bit to the CODEC structure indicating if a cache sync is required.
By default this will be set if a cache only write is done to a soc-cache
register cache. This allows us to avoid syncing the cache back after
using cache only writes if there were no changes.Signed-off-by: Mark Brown

Currently the soc-cache code will always write to the device, meaning
that we need the device to be powered and active at pretty much all
times the system is active. Allowing cache only writes lays some
groundwork for future enhancements to allow devices to be put into a
full off state when the audio subsystem is idle.Signed-off-by: Mark Brown

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

This converts all the Wolfson drivers using this format (the only devices
that do) except WM8753 to use it.Signed-off-by: Mark 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
-
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.

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.Signed-off-by: Mark Brown
