Subject: [PATCH v5 00/80] drm/vc4: Support BCM2711 Display Pipeline
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 and DSI
outputs have been tested too).
Let me know if you have any comments
Maxime
