Merge tag 'tegra-for-4.16-memory' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/drivers
Pull "memory: tegra: Changes for v4.16-rc1" from Thierry Reding: The Tegra memory controller driver will now instruct the SMMU driver to create groups, which will make it easier for device drivers to share an IOMMU domain between multiple devices. Initial Tegra186 support is also added in a separate driver. * tag 'tegra-for-4.16-memory' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tegra/linux: iommu/tegra-smmu: Fix return value check in tegra_smmu_group_get() iommu/tegra: Allow devices to be grouped memory: tegra: Create SMMU display groups memory: tegra: Add Tegra186 support dt-bindings: memory: Add Tegra186 support dt-bindings: misc: Add Tegra186 MISC registers bindings
