From f16eedf982b8e580ad863f36b1ec7175e877ea76 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Mon, 9 Aug 2021 17:11:02 +0200 Subject: [PATCH] arm64: dts: qcom: msm8998: Add disabled support for lpass iommu for q6 Add support for the LPASS (Q6) SMMU and keep it disabled as this is used only when the audio DSP is present and used, which is not mandatory to have. It is expected for board-specific device-trees to enable this node if supported.
