+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.
