[PATCH 00/11] arm64: tegra: Add NVIDIA Jetson AGX Orin support

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Hi,

This set of patches adds support for the new NVIDIA Jetson AGX Orin
module and the corresponding developer kit. It builds on the existing
Tegra234 support introduced a while ago for the simulation VDK platform
and updates a couple of details and adds a few more things that have
changed since then.

Most of this work was done by Mikko Perttunen.

Mikko Perttunen (7):
  dt-bindings: Update headers for Tegra234
  misc: sram: Add compatible string for Tegra234 SYSRAM
  arm64: tegra: Add clock for Tegra234 RTC
  arm64: tegra: Update Tegra234 BPMP channel addresses
  arm64: tegra: Fill in properties for Tegra234 eMMC
  arm64: tegra: Add Tegra234 TCU device
  arm64: tegra: Add NVIDIA Jetson AGX Orin Developer Kit support

Thierry Reding (4):
  dt-bindings: tegra: Describe recent developer kits consistently
  dt-bindings: tegra: Document Jetson AGX Orin (and devkit)
  dt-bindings: sram: Document NVIDIA Tegra SYSRAM

Hi Greg,

I forgot to Cc you on the initial submission, not realizing that I had
this one-line driver change mixed into a set of DT bindings and device
tree updates.

Quoting in full. Would you mind if I pick this up into the Tegra tree,
or do you want me to resend this to you for inclusion in your tree?

Thanks,
Thierry

A separate stand-alone patch would be great as b4 wants to grab all of

[PATCH 06/11] arm64: tegra: Fixup SYSRAM references

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

The json-schema bindings for SRAM expect the nodes to be called "sram"
rather than "sysram" or "shmem". Furthermore, place the brackets around
the SYSRAM references such that a two-element array is created rather
than a two-element array nested in a single-element array. This is not
relevant for device tree itself, but allows the nodes to be properly
validated against json-schema bindings.
