Commit e762232f ("arm64: tegra: Add ISO SMMU controller for Tegra194")
added the ISO SMMU for display devices on Tegra194. The SMMU is enabled by
default but not hooked up to the display controllers yet because we do not
have a way to pass frame-buffer memory from the bootloader to the kernel.
However, even though the SMMU is not hooked up to the display controllers'
SMMU faults are being seen if a display is connected. Therefore, keep the
ISO SMMU disabled by default for now.

case they would end up merged in the final DTB), append the name of the

The display controllers are attached to a separate ARM SMMU instance
that is dedicated to servicing isochronous memory clients. Add this ISO
instance of the ARM SMMU to device tree.

Please note that the display controllers are not hooked up to this SMMU
yet, because we are still missing a means to transition framebuffers
used by the bootloader to the kernel.
