Commit 59a42707a094 ("arm64: tegra: Add interconnect properties for
Tegra210") populated interconnect properties for Tegra210 and this is
preventing the Tegra DRM driver from probing successfully. The following
error is observed on boot ...

  drm drm: failed to initialize 54240000.dc: -517

For now revert this change, until a fix is available.

Hi Arnd,

this is the only patch that I think we need in v6.19 for now, so do you
want me to send a PR or would you rather pick this up directly?

Here's a link to the patchwork for this, for convenience:

	https://patchwork.ozlabs.org/project/linux-tegra/patch/20251217104744.184153-1-jonathanh@nvidia.com/

Acked-by: Thierry Reding <redacted>

Please can you let us know if you can pick this up as a fix for v6.19? 
This is still the only fix we have outstanding that needs to be merged.

Sorry I missed the earlier message. I've applied it now, but in
the future please forward patches to soc@lists.linux.dev if you
want make sure they don't get lost. A pull request or a separate
patch works just as well, but sending it to the list means it
shows up in patchwork[1].

     Arnd
