From 7edd7961e58d531d19758134919de13dac47bcbe Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 28 Oct 2019 13:37:08 +0100 Subject: drm/tegra: Simplify IOMMU group selection All the devices that make up the DRM device are now part of the same IOMMU group. This simplifies the handling of the IOMMU attachment and also avoids exhausting the number of IOMMUs available on early Tegra SoC generations.
