+Subject: [PATCH] arm64: dts: qcom: qrb2210-rb1: Swap UART index
+
+Newer RB1 board revisions have a debug UART on QUP0. Sadly, it looks
+like even when ordering one in retail, customers receive prototype
+boards with "Enginering Sample" written on them.
+
+Use QUP4 for UART to make all known RB1 boards boot.
