This code is not working currently and it can be removed. There is a
conflict in sharing resources with the actual HDMI driver and with
the ASoC HDMI audio DAI driver.

The OMAP5 HDMI audio implementation needs HDMI_AUDIO_LAYOUT_6CH in
hdmi_core_audio_layout enum. I found the correct value from ti-linux
3.8 tree.

Name the anonymous hdmi struct as omap_hdmi. Move the struct definition to
hdmi.h and turn core member into a pointer to deal with it's different
definitions for omap4 and omap5. Make associated changes to hdmi4.c
and hdmi5.c.

I didn't understand this one. Why did you make struct hdmi_core_data a
pointer?

That is because there is no point to it :)... my mistake made in a

Integrate ASoC DAI component driver in to the OMAP hdmi driver. The
patch also updates the relevant entry in ti,omap5-dss DT binding
document. The driver registers a dummy hdmi codec driver and a
simple-card driver to produce a fully functional ALSA device. The DAI
driver is implemented in hdmi_audio.c, but it still needs to be
registered from hdmi4.c or hdmi5.c.

Add help section to OMAP4_DSS_HDMI_AUDIO with dependency to
OMAP4_DSS_HDMI and select for newly created OMAP_DSS_HDMI_AUDIO. The
OMAP_DSS_HDMI_AUDIO option is for common HDMI audio support and it is
is dependent on SND_SOC.
Also selects SND_OMAP_SOC, SND_SOC_HDMI_CODEC, and SND_SIMPLE_CARD for
OMAP2_DSS if OMAP_DSS_HDMI_AUDIO is enabled.

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.
