[PATCH v2 0/7] Host1x/VIC support on Tegra264

[Mikko Perttunen <mperttunen@nvidia.com>]

Hello everyone,

this series adds support for Host1x and VIC on Tegra264 SoCs.
The Host1x side is not very interesting, just adding the usual register
definitions and other information. One thing of note is that multimedia
engines apart from VIC have moved away from Host1x on this generation.

On the VIC side, there is a bit more of a change, as the VIC Falcon is
now RISC-V based. Unlike NVDEC, VIC is still "externally booted", so
the boot sequence is very similar to before.

host1x uapi-test[1] has been updated for Tegra264. Necessary headers for 
constructing VIC jobs have been added to open-gpu-doc[2].

Patches 1 and 2 add new compatible strings to Host1x and VIC device tree
bindings.

Patch 3 fixes the context device device tree parsing code to handle
iommu-map entries with length more than 1.

Patch 4 adds Tegra264 support to the Host1x driver.

Patches 5 and 6 add Tegra264 support to the VIC driver.

Patch 7 adds Host1x and VIC nodes to the Tegra264 device tree.

Thank you,
Mikko
