drm/i2c: tda998x: add video and audio input configuration This patch adds tda998x specific parameters to allow it to be configured for different boards using it. Also, this implements rudimentary audio support for S/PDIF attached controllers.

drm/i2c: tda998x: Improve tda998x_configure_audio() audio related pdata Define struct tda998x_audio_params in include/drm/i2c/tda998x.h and use it in pdata and for tda998x_configure_audio() parameters. Also updates tda998x_write_aif() to take struct hdmi_audio_infoframe * directly as a parameter. Signed-off-by: Jyri Sarha <jsarha@ti.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

drm/i2c: tda998x: Register ASoC hdmi-codec and add audio DT binding Register ASoC HDMI codec for audio functionality and adds device tree binding for audio configuration. With the registered HDMI codec the tda998x node can be used like a regular codec node in ASoC card configurations. HDMI audio info-frame and audio stream header is generated by the ASoC HDMI codec. The codec also applies constraints for available sample-rates based on Edid Like Data from the display. The device tree binding document has been updated [1]. Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x: Add support of a DT graph of ports"-patch [2]. There may still be some identical lines left from the original patch and some of the ideas have come from there.
