4 Subject: [PATCH] drm/vc4: hdmi: Implement a register layout
5 abstraction
6
7 The HDMI controllers found in the BCM2711 have most of the registers
8 reorganized in multiple registers areas and at different offsets than
9 previously found.
10
11 The logic however remains pretty much the same, so it doesn't really make
12 sense to create a whole new driver and we should share the code as much as
13 possible.
14
15 Let's implement some indirection to wrap around a register and depending on
16 the variant will lookup the associated register on that particular variant.
