+Subject: [PATCH] drm/vc4: hdmi: Implement a register layout
+ abstraction
+
+The HDMI controllers found in the BCM2711 have most of the registers
+reorganized in multiple registers areas and at different offsets than
+previously found.
+
+The logic however remains pretty much the same, so it doesn't really make
+sense to create a whole new driver and we should share the code as much as
+possible.
+
+Let's implement some indirection to wrap around a register and depending on
+the variant will lookup the associated register on that particular variant.
