[U-Boot] [PATCH 00/30] dm: sound: Convert to driver model

[Simon Glass]

The sound subsystem has never been converted to driver model. It is not
widely used and is a little bit complicating 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. So far this is only
tested on snow. I intend to test also on spring and pit/pi when I can.
I do not have smdk5250/5420 or arndale to test with.
