Subject: [PATCH v2 00/13] Host1x support on Tegra234

From: Mikko Perttunen <mperttunen@...dia.com>

-------------
Merging notes
-------------

This series should be applied on top of the Host1x context isolation
series.

-------------
Changes in v2
-------------

Rebased on top of v5.19-rc3.

Updated Host1x device tree schema based on Rob's comments.

No changes to node names done, as that is a change that should be
done uniformly in a separate series for all Tegra generations,
if deemed appropriate.

Original message

Hi all,

This series adds support for Host1x and VIC on the recently released
Tegra234 (Orin) SoC. It's split into the following parts:

* Device tree binding updates
* Cleanup in host1x driver
* Add programming of new registers and old registers that now need to
  be programmed to a non-reset value
* Tegra234 device data and headers
* Rewrite of the job opcode sequence, and related patches to
  support MLOCKs on Tegra186+.

The rewrite of the job opcode sequence brings Tegra186, Tegra194 and
Tegra234 support to a 'full-featured' status that is necessary to
support all host1x features in the future. This should not have any
impact on older SoCs.

This series should be applied on top of the Host1x context isolation
series.

Tested on Jetson AGX Xavier and Jetson AGX Orin.

Thanks,
Mikko
