Hi all,
this adds support for the HDMI output pipeline on the i.MX8MP. It currently depends on the i.MX8MP HDMI power domain series [1] and support for the new LCDIF [2] in the i.MX8MP. I guess the implementation presented here also still has some warts that require fixing and the individual patches most likely need to go through different maintainer trees, so I don't expect this series to be applied right away.
However this complete series should allow people to test it more easily and provide feedback on the implementation with the full picture available.
Compared to downstream this implementation actually allows to power down the separate HDMI PHY power domain when the display is inactive or no HDMI cable is connected.
Regards, Lucas
