The sound subsystem has never been converted to driver model. It is is a little bit complicated since it needs an audio codec, an i2s device and a sound device to bring them together.
Sound is the main subsystem holding back removal of CONFIG_DM_I2C_COMPAT.
This series takes a stab at doing the conversion. This is tested on snow, pit and pi. I do not have smdk5250/5420 or arndale to test with.
Changes in v2: - Add fix for pit and pi also - Fix up tabs in this commit instead of the later one - Use Kconfig instead of defconfig to define DM_SOUND - Update 'init' command to print the error code - Correct conversion for pit - Use void * for i2c and sound data - Add new patch to move common code out of maxim98095 - Add new patch with support for max98090 - Correct conversion for pit and pi, updating commit message - Add new patch to convert sandbox to use driver model - Drop CONFIG_DM_SOUND from all defconfig files - Fix up sandbox files to remove old code - Update the rest of the samsung boards - Remove unused sandbox code also - Drop patches previously applied - Add new patch to fix license headers - Add new patch to tidy up error codes in max98095 - Add new patch to use the correct number of channels for sound
