[PATCH v3] ALSA: sound/atmel/ac97c.c: Add device tree support

[PATCH v3] ALSA: sound/atmel/ac97c.c: Add device tree support

[Alexander Stein]

This adds device tree support for the AC97 controller. It uses the
soc-ac97link bindings, but actually only ac97-reset is used.

Changes in v3:
* Renamed the compatible string to atmel,at91sam9263-ac97c
* Added 'Acked-By Alexandre Belloni <alexandre.belloni@free-electrons.com>'

Changes in v2:
* It now uses the soc-ac97link bindings (partly) instead of defining its own.
  This should ease the transition to ASoC once a new driver has been written.

[PATCH v3] ARM: at91/dt: sam9263: Add ac97 device node

[Alexander Stein]

Now that the implementation has been applied to sound/for-next (https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/log/?h=for-next
), who is going to pick the related patches (this one and the other two adding documentation and default config)?
