This set of patches fixes OMAP4+ HDMI audio. The structure of the
implementatin 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 component driver into the
HDMI driver.
The idea is to use an existing ASoC component driver API instead of
creating a new custom API for each HDMI IP and to avoid splitting the
driver to half for separate video and audio parts connected with the
API.
The new implementation also uses simple-audio-card for a machine
driver instead of having its own HW specific machine driver.
The patches are based on 3.15-rc2 merged with
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next
and
git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git work/dss-dt-omap5
Everything is pushed here here:
git://git.ti.com/~jyrisarha/ti-linux-kernel/jyrisarhas-audio-video-linux-feature-tree.git omap-hdmi-audio

Jyri

Integrate ASoC DAI component driver in to the OMAP4 hdmi driver. The
implementation removes the callbacks for an external audio driver and
the old external DAI driver does not work anymore after this patch.
The patch also updates the relevant entry in ti,omap4-dss DT binding
document.

hdmi_core_audio_layout enum. I found the correct value from ti-linux

Integrate ASoC DAI component driver in to OMAP5 hdmi driver. The
implementation removes the callbacks for an external audio driver and
the old external DAI driver does not work anymore after this patch.

Removes omap-hdmi DAI driver, omap-hdmi-card driver, the related
Kconfig options, and Makefile entries. The HDMI DAI drivers has been
integrated directly to OMAP4+ HDMI drivers and simple-card driver is
used instead of omap-hdmi-card driver.

Removes all code related to external audio driver callbacks. There is
no need for those now that sound/soc/omap/omap-hdmi.c is removed.
