[PATCH RFC v2 0/7] Implement generic ASoC HDMI codec

Only the first three patches are meant for serious review.

The ASoC part should be ready for review in other respects but the
EDID SADs handling is waiting for Russell King's DRM ELD helper
patches. There is a copy-pasted not-to-be-merged patch with the same
functionality in the patch series.

The tda998x part is not complete and I do not think Jean-Francois'
binding are ready as such either. At least the usage of reg property in
a port node for something that is not an address or even guaranteed to
be unique is not a good idea. Some documentation of how to configure
AP0-AP4 pins (REG_ENA_AP?) would help in making a proper binding for
the tda998x audio configuration.

These patches, my tilcdc refactoring[1], and my latest BCLK fixes for
davinci-mcasp driver [2], can be found in a branch that produces
working HDMI audio on Beaglebone-Black here:
