Add a machine driver to support the ADAU1701 SigmaDSP processors on Analog Devices BF5XX evaluation boards.
So, I keep on complaining about the way these drivers are just generic to any random Blackfin plus CODEC combination rather than being board specific. It'd be good if we could improve this, even adding something into the driver name to make it clear these are for the EVB would help.
I think this is due, that the codecs them-self sit on an add-on board to the bf5xx eval boards. So you have two boards, the bf5xx eval board with has the codec eval board connected to it. That's why it it is kept so generic. You could connect the codec eval board to any of the bf5xx boards.
But it's about the same as all the other drivers so...
+static struct snd_soc_dai_link bf5xx_adau1701_dai[] = {
- {
.name = "adau1701",.stream_name = "adau1701",.cpu_dai_name = "bfin-i2s.0",.codec_dai_name = "adau1701",.platform_name = "bfin-i2s-pcm-audio",.codec_name = "adau1701.0-0034",.ops = &bf5xx_adau1701_ops,- },
- {
.name = "adau1701",.stream_name = "adau1701",.cpu_dai_name = "bfin-i2s.1",.codec_dai_name = "adau1701",.platform_name = "bfin-i2s-pcm-audio",.codec_name = "adau1701.0-0034",.ops = &bf5xx_adau1701_ops,- },
For example this mapping could vary between systems, and I guess there may be some possiblity that the CODEC I2C address could change.
The I2C address is specific to the add-on board and since there is only one adau1701 eval board it should be static.
