Subject: [PATCH 5/8] arm64: dts: qcom: Add SDX75 platform and IDP board support
Date:   Fri, 19 May 2023 14:39:07 +0530
Message-Id: <1684487350-30476-6-git-send-email-quic_rohiagar@quicinc.com>
In-Reply-To: <1684487350-30476-1-git-send-email-quic_rohiagar@quicinc.com>
References: <1684487350-30476-1-git-send-email-quic_rohiagar@quicinc.com>
Precedence: bulk

Add basic devicetree support for SDX75 platform and IDP board from
Qualcomm. The SDX75 platform features an ARM Cortex A55 CPU which forms
the Application Processor Sub System (APSS) along with standard Qualcomm
peripherals like GCC, TLMM, UART, QPIC, and BAM etc... Also, there
exists the networking parts such as IPA, MHI, PCIE-EP, EMAC, and Modem
etc..

This commit adds basic devicetree support.
