From 4827f0cabc16ab83a6ad5c058d26d966beaef8f2 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Sun, 22 Nov 2020 23:23:05 -0600 Subject: [PATCH] arm64: dts: qcom: sdm845: Limit ipa iommu streams [ Upstream commit 95e6f8467c83c4074a6f6b47bad00653549ff90a ] The Android and Windows firmware does not accept the use of 3 as a mask to cover the IPA streams. But with 0x721 being related to WiFi and 0x723 being unsed the mapping can be reduced to just cover 0x720 and 0x722, which is accepted.
