Hi everyone,
Here's a (pretty long) series to introduce support in the VC4 DRM driver for the display pipeline found in the BCM2711 (and thus the RaspberryPi 4).
The main differences are that there's two HDMI controllers and that there's more pixelvalve now. Those pixelvalve come with a mux in the HVS that still have only 3 FIFOs. Both of those differences are breaking a bunch of expectations in the driver, so we first need a good bunch of cleanup and reworks to introduce support for the new controllers.
Similarly, the HDMI controller has all its registers shuffled and split in multiple controllers now, so we need a bunch of changes to support this as well.
Only the HDMI support is enabled for now (even though the DPI output has been tested too). There's a couple of rough edges still that should be addressed in the next versions: - Dual output doesn't work - The transposer (and thus writeback) doesn't work either and conflicts with the output mux too.
Let me know if you have any comments Maxime
