From 0da2eff44e78ded247fe35d8a3f73508263d0948 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Wed, 11 Jan 2023 18:00:04 +0530 Subject: [PATCH] arm64: dts: qcom: sm8450: Allow both GIC-ITS and internal MSI controller The devicetree should specify both MSI implementations and the OS/driver should choose the one based on the platform requirements. Currently, Linux DWC driver will choose GIC-ITS over the internal MSI controller.
