[PATCH 1/2] arm64: dts: qcom: eliza-mtp: Fix the debug UART index
From: Abel Vesa
Date: Wed May 13 2026 - 08:34:54 EST
The Eliza MTP debug UART is QUPv3 WRAP2 SE5. The existing DTS labels it
as uart14, but the serial-engine index for this block is actually 13.
Rename the SoC UART label and pinctrl state to uart13 and update the MTP
alias and node reference accordingly.
Fixes: af20af39fc09 ("arm64: dts: qcom: Introduce Eliza Soc base dtsi")
Fixes: 2a5d4fc6f3f7 ("arm64: dts: qcom: eliza: Enable Eliza MTP board support")
