Subject: [PATCH v1] arm64: dts: qcom: sc7280: Remove CTS/RTS configuration
Date: Tue, 16 Apr 2024 16:26:50 +0530
Message-Id: <20240416105650.2626-1-quic_vdadhani@quicinc.com>
Precedence: bulk

Remove CTS and RTS pinctrl configuration for UART5 node as
it's designed for debug UART for all the board variants of the
sc7280 chipset.

Also change compatible string to debug UART.

Fixes: 38cd93f413fd ("arm64: dts: qcom: sc7280: Update QUPv3 UART5 DT node")
