In this series I gathered patches touching various subsystems to make the overall review easier, finally I'm going to post independently patches for each subsystem and the dts patch(es) will be postponed to subsequent merge window.
The main purpose of this series is to add audio codec interface to the Exynos DRM driver, so HDMI audio can be properly supported, also on boards where HDMI is the only connector available for audio.
Currently in mainline the ASoC simple-card is used for Odroid XU3, I decided to change it and use a dedicated ASoC machine driver, which allowed to implemement specific clock settings (EPLL and the I2S root clock adjusted to audio sample rates) and to ensure proper number of audio channels gets negotiated in multicodec system configuration.
This series is based on v4.11-rc6, has been tested on Odroid XU3.
