From c9ec155b5962233aff3df65210bd6a4788dee21c Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Mon, 18 Nov 2019 17:18:23 -0800 Subject: [PATCH] arm64: dts: qcom: msm8998-mtp: Add alias for blsp1_uart3 The msm_serial driver has a predefined set of uart ports defined, which is allocated either by reading aliases or if no match is found a simple counter, starting at index 0. But there's no logic in place to prevent these two allocation mechanism from colliding. As a result either none or all of the active msm_serial instances must be listed as aliases. Define blsp1_uart3 as "serial1" to mitigate this problem.
