[U-Boot] [PATCH v2 00/22] dm: sound: Convert to driver model

[Simon Glass]

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
