[RESEND PATCH v3 0/2] ASoC: atmel-classd: add driver for Atmel CLASSD

[Songjun Wu]

The Audio Class D Amplifier driver includes two parts.
1) Driver code to implement the Audio Class D Amplifier function.
2) Device tree binding document, it describes how to add the Audio
   Class D Amplifier in device tree.

Changes in v3:
- Remove '.owner' field in variable 'atmel_classd_driver',
  since the core will do it.
- Correct 'IS_ERR(dd->aclk)' to 'IS_ERR(dd->gclk)',
  when geting the clock 'dd->gclk'.

Changes in v2:
- Change the "Mono", "Swap" and "Deemphasis" controls to
  "Mono Switch", "Swap Switch" and "Deemphasis Switch".
- Merge "EQ Bass", "EQ Medium" and "EQ Treble" controls
  into one "EQ" control.
- Change the "single-ended" and "differential" to
  "Single ended", "Differential".
- Merge separate left and right controls into one single
  stereo control.
- Add a warning if the user trys to specify an invalid
  value in function "atmel_classd_codec_probe".
- Use the "dev_get_regmap()" in function
  "atmel_classd_codec_get_remap".
- Check for errors when invoking the "clk_prepare_enable".
- Remove the "dev_info" in function "atmel_classd_probe".
- Add some code to create a sound card in function
  "atmel_classd_probe".
- Remove the DT node "Sound" and the related code.
- Delete the device node "Sound" in dts.
