[PATCH v3 1/3] ASoC: Add ADAV80x codec driver

[PATCH v3 1/3] ASoC: Add ADAV80x codec driver

[Lars-Peter Clausen]

This patch adds support for the Analog Devices ADAV801 and ADAV803 audio codec.

Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

---
Changes since v2:
* Allow to enable/disable SYSCLK outputs by using snd_soc_dai_set_sysclk
Changes since v1:
* Sync register on resume
* Don't use arrays for the mux enums and controls
* Rework PLL handling. Use DAPM for powering the PLL and OSC down and use
  set_sysclk to select the system clock instead of doing this implicitly in
  set_pll.

[PATCH v3 3/3] Blackfin: bf537: Stamp: Register adav801 codec and ASoC machine driver

[Lars-Peter Clausen]

There is already an entry in the spi device table for the codec, but the
modalias was wrong. Also the config symbol name for the codec is wrong, so this
is fixed as well.
