From 2c85e517b159051fd33c5245d406dd1dcbb97b24 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Sun, 9 Jul 2017 19:36:14 +0300 Subject: ARM: tegra: Register host1x node with IOMMU binding on Tegra124 This registers the host1x node with the SMMU (as HC swgroup) to allow the host1x code to attach to it. It avoid failing the probe sequence, which resulted in the Tegra DRM driver not probing and thus nothing being displayed on-screen.
