[PATCH v2 0/3] ASoC: Add devicetree support for spdif dummy codecs.

[Marek Belisko]

changes from v1 (for patch 2 and 3):
- add prefix linux for compatible property (for both tx and rx)
- rename spdif_transceiver.c to spdif_transmitter.c
- add bindings documentation

Marek Belisko (3):
  ASoC: spdif_transceiver: Change driver filename to
    spdif_transmitter.c.
  ASoC: spdif_transmitter: Add DT support.

[PATCH v2 1/3] ASoC: spdif_transceiver: Change driver filename to spdif_transmitter.c.

[Marek Belisko]

Transceiver usually means receiver + transmitter. This codec can do only
transmit. Update driver accordingly.

Marek,

I remember Daniel commenting on the name already, but
what about "spdif-transmitter" and "spdif-receiver" respectively?
That is very generic and should allow to remove "linux," prefix.
And there is a lot of drivers using more informative compatible
strings compared to the driver name.

Sebastian

Agree.

Not sure if linux, prefix can be removed. I believe (at least what 
documentation said) is that <manufacturer>,<model> must be format for 
compatible.

Yeah, you're supposed to have some prefix.  I guess for stuff that we're
really happy is totally generic we could use "generic" or something but
it doesn't make much practical difference.
