[alsa-devel] [PATCH v2 0/7] ASoC: pcm512x: Clock master modes

[Peter Rosin]

From: Peter Rosin <peda at axentia.se>

Hi!

[ Note that the dt change is in patch 5/7, for those only interested
  in that particular bit. ]

This series implements BCLK master modes for the pcm512x driver. It has
only been tested with the pcm5142 chip, but they are from the same family
and should be compatible. I have mainly used the spec for the newer
pcm5242 chip (also from the same family) as it fills in a lot of blanks
in the pcm512x/pcm514x specs.

The code has also seen most of its testing in a 3.10 environment, so
there might be some forward-porting warts. But it is able to play sound
in 3.18 as well, and most of the changes have little to do with anything
but the clocking in the chip itself.

Changes since v1:
- Use snd_soc_params_to_frame_size and snd_soc_params_to_bclk instead of
  implementing home-grown versions based on the physical width. The
  I2S-communication will no longer have padding bits for S24_LE.

Cheers,
Peter
