The i.MX8M Plus has an HDMI controller, which depends on several other systems. The Parallel Video Interface (PVI) and the HDMI-TX are already in the Linux-Next staging area 20240209, but the HDMI PHY driver and several device trees updates are still needed. This series is adapted from multiple series from Lucas Stach with edits and suggestions from feedback from various attemps, but it since it's difficult to use and test them independently, I merged them into on unified series. The version history is a bit ambiguous since different components were submitted at different times and had different amount of attempts. The previous attempt I did used the wrong starting point for the PHY, so this update includes a newer starting point with tags from that version and fixes from various people's feedback. I hope I caught them all, but I apologize if I missed something. Any tags from the previous attempt I made were intentionally dropped, because of the significant change, but I kept tags from the newer version I grabbed from patchwork. Because several items from the last attempt were merged, this series is only focussed on adding the HDMI PHY driver, and enabling the power domain, irqsteer interrupt controller, and HDMI pipeline in the device tree. The version numbers are a bit strange since these all got pulled from various attempts with different versions, but I wanted to push them together as a series to complete the pending work. This series restarted at V4 based on the version of the PHY driver and the other drivers and power-domain changes have been applied already. V5 primarily updates feedback from the PHY driver itself, but a small adjustment was made to the register size in the device tree.
