Subject: [PATCH 0/3] ALSA: update sample rate definition for eARC

This patchset updates some sample rate definition for eARC support.
Notably it:
 * adds the definition for 128kHz
 * update the ASoC spdif codecs to include all supported rates, up to 768kHz
 * adds missing IEC958 definition for 128k, 352.4k, 384k and 705.6kHz

On that last point, as noted in the related commit description, I'd like to
stress that I have found the definitions using a testing equipement. I
do not have access to the IEC958 specification. It would be best if someone
with access to this specification could review/ack patch #2, before
applying it.

Jerome Brunet (3):
  ALSA: pcm: add support for 128kHz sample rate
  ALSA: IEC958 definition for consumer status channel update
  ASoC: spdif: extend supported rates to 768kHz
