Subject: [PATCH] arm64: dts: qcom: qrb2210-rb1: Swap UART index
Git-commit: 973c015facabcbd320063648010942c51992c1a1
Patch-mainline: v6.7-rc1
References: git-fixes
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.
