Subject: [PATCH] arm64: dts: renesas: preserve drm HDMI connector naming on KF
Kingfisher adds encoders on ports 0 and 2 of the R-Car
display unit. The bare ULCB SK has only an HDMI encoder
in use on port 1. When the system is booted with an SK
dtb, port 1's HDMI encoder is assigned as HDMI-A-1 because
it is the first (and only) encoder present. When booting
a KF dtb, port 0's HDMI encoder preceeds port1 in the dtb due
to incremental ordering of the endpoint port nodes. This causes
the KF HDMI to be assigned HDMI-A-1 and the SK HDMI to be assigned
as HDMI-A-2. In order to preserve the SK's HDMI output naming as
connector HDMI-A-1, reorder the endpoint port nodes so that port1
is first.
