From c0a824edb6bf694a2d5a9eede29e1628f093cb22 Mon Sep 17 00:00:00 2001 From: Bryan Hinton Date: Sun, 21 Sep 2025 22:58:09 -0500 Subject: [PATCH] arm64: dts: mediatek: mt7981b: add labels for UART0/1/2 nodes Add stable labels (uart0, uart1, uart2) to the MT7981B SoC UART nodes so board DTS files can reference them directly. This change is purely cosmetic and introduces no functional differences. Verification: Built dtbs and boot-tested mainline Image+DTB via U-Boot on MT7981B hardware; decompiled DT shows the uart0 label present and the serial0 alias (or absolute path) resolves to serial@11002000.
