[PATCH 00/21] ASoC: Use static DAI format setup

[PATCH 00/21] ASoC: Use static DAI format setup

[Lars-Peter Clausen]

There is still a rather large amount of board driver which manually call
snd_soc_dai_set_fmt() for both the CPU and the CODEC DAI, while pretty much
all of them can use static DAI setup by setting the dai_fmt field in the
snd_soc_dai_link struct.

Using the later method results in shorter and cleaner code and will also
make it easier to eventually switch to a component type independent way to
specify the clock master/slave settings (Right now the meaning of the value
depends on whether a DAI belongs to a CODEC or not).

This series converts all the trivial cases of snd_soc_dai_set_fmt() users to
use the dai_fmt field instead.

[PATCH 09/21] ASoC: zylonite: Use static DAI format setup

[Lars-Peter Clausen]

Set the dai_fmt field in the dai_link struct instead of manually calling
snd_soc_dai_fmt(). This makes the code cleaner and shorter.
