From b94c280d0b45d1304e920f6edb07141161237a5f Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Mon, 4 May 2020 13:13:50 -0500 Subject: arm64: dts: sdm845: add IPA iommus property 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. Signed-off-by: Alex Elder Signed-off-by: David S.
