Subject: [PATCH] arm64: dts: qcom: ipq8074: add SMEM support
Date: Thu, 2 Sep 2021 23:47:08 +0200 [thread overview]
Message-ID: <20210902214708.1776690-1-robimarko@gmail.com> (raw)
IPQ8074 uses SMEM like other modern QCA SoC-s, so since its already
supported by the kernel add the required DT nodes.
