[alsa-devel] about ALSA subdevice

[lei.ge at freescale.com]

Dear ALSA-devel members,
I want to add subdevices to our ASoC drivers, for example:
card 0: imxesai [imxesai], device 0: imxesai PCM [imxesai PCM]
  Subdevices: 3/4
  Subdevice #0: subdevice #0
  Subdevice #1: subdevice #1
  Subdevice #2: subdevice #2
  Subdevice #3: subdevice #3
I saw BCM2835 use 8 subdevices in sound/arm/, but it is not standard ASoC driver.
What should I do  if I want to add subdevices in standard ASoC driver?
Can anyone show me an example?
Thanks!
