Subject: [PATCH net-next 1/4] arm64: dts: sdm845: add IPA iommus property
Date: Fri, 1 May 2020 16:46:22 -0500 [thread overview]
Message-ID: <20200501214625.31539-2-elder@linaro.org> (raw)
In-Reply-To: <20200501214625.31539-1-elder@linaro.org>
Add an "iommus" property to the IPA node in "sdm845.dtsi". It is
required because there are two regions of memory the IPA accesses
through an SMMU. The next few patches define and map those regions.
