Please add also your own closing "Signed-off-by" tag, please reference
to "Developer's Certificate of Origin 1.1", point (c), it is found in
Documentation/process/submitting-patches.rst

My assumption is that Thierry would prefer to get 4 separate patches,
one for each platform, please split the patch.
Also thanks for your time and your efforts applied to push my occasional
change, please feel free to take your own authorship for 3 out of 4 patches.

Unfortunately Thierry hasn't yet replied, but my assumption is that
the list of compatibles should be extended with one more SoC specific
value like
compatible = "nvidia,tegra114-sysram", "mmio-sram";
I'm not sure, if Tegra maintainers want to see a new compatible
described in Documentation/devicetree/bindings.

The considerations from above are applicable to the rest of
the touched platforms.
