[PATCH v3 00/14] Rework OMAP4+ HDMI audio support

[Jyri Sarha <jsarha@ti.com>]

Question to ASoC maintainers:
  Do feel it is Ok to put ASoC code outside sound/soc the way I do
  in these patches (in patch 0006 particularly)?

The patches are based on:
git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git for-next

The base, the patches, and couple of additional not-to-be-merged
omap2plus_defconfig patches can be found here:

git://git.ti.com/~jyrisarha/ti-linux-kernel/jyrisarhas-audio-video-linux-feature-tree.git omap-hdmi-audio

Changes since v2 version of the patches:
- Add "OMAPDSS: hdmi_common: hdmi_compute_acr is needed for OMAP5 HDMI audio too"
- Fix "OMAPDSS: hdmi: Make hdmi structure public". There was no need to make
  "core"-member a pointer.
- Make functional division between hdmi_audio.c and hdmi[45].c more clear.
  hdmi_audio.c does not touch anything but "audio"-member in omap_hdmi struct
  that is stored in drvdata.

The patch set fixes OMAP4+ HDMI audio. The structure of the
implementation looks a bit different than before. Instead of creating
a driver specific API for a separate ASoC component driver to connect
to, this implementation integrates an the ASoC cpu-dai component
driver into the HDMI driver. Also the other ASoC component drivers
needed for operational audio are automatically registered by the HDMI
driver. There is no need to add anything to the device tree as long as
the nodes needed for HDMI video are there.

Big part of the HDMI audio code is still unchanged and there is a need
for a cleanup there. Also there is still probably something wrong with
speaker mapping of multi-channel streams. I will get back to cleaning
up these issues later.

Best regards,
Jyri
