Subject: arm64: dts: qcom: eliza-mtp: Fix the debug UART index
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=179d11c1c0cfaddcfc984edc3c1863ab600f679f;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: qcom: eliza-mtp: Fix the debug UART index

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")
