Subject: drm/vc4: hdmi: Store the encoder type in the variant structure
Git-commit: 7d73299dad3edd3e3caf7b9d2817c3db931a26d3
Patch-mainline: v5.10-rc1
References: jsc#SLE-15318
The vc4 CRTC will use the encoder type to control its output clock
muxing. However, this will be different from HDMI0 to HDMI1, so let's
store our type in the variant structure so that we can support multiple
controllers later on.
