    drm/tegra: hdmi: Enable audio over HDMI · 2ccb396e
    Thierry Reding 提交于
    In order to use the HDA codec to forward audio data to the HDMI codec it
    needs the ELD that is parsed from the monitor's EDID.
    
    Also implement an interoperability mechanism between the HDA controller
    and the HDMI codec. This uses vendor-defined scratch registers to pass
    data from the HDMI codec driver to the HDMI driver (that implements the
    receiving end of the HDMI codec). A custom format is used to pass audio
    sample rate and channel count to the HDMI driver.
