Since commit 26c9d152ebf3 ("dt-bindings: tpm: Consolidate TCG TIS
bindings"), several issues are reported by "make dtbs_check" for arm64
devicetrees:

The compatible property needs to contain the chip's name in addition to
the generic "tcg,tpm_tis-spi" and the nodename needs to be "tpm@0"
rather than "cr50@0":

  tpm@1: compatible: ['tcg,tpm_tis-spi'] is too short
        from schema $id: http://devicetree.org/schemas/tpm/tcg,tpm_tis-spi.yaml#

  cr50@0: $nodename:0: 'cr50@0' does not match '^tpm(@[0-9a-f]+)?$'
        from schema $id: http://devicetree.org/schemas/tpm/google,cr50.yaml#

Fix these schema violations.

phyGATE-Tauri uses an Infineon SLB9670:

The commit mentioned above, 26c9d152ebf3 ("dt-bindings: tpm: Consolidate
TCG TIS bindings") landed in Linus' tree yesterday.

Because this consists only of fixes, I think it could be picked up and
forwarded to Linus at any time, even outside the merge window.

The issues reported for imx8m*-venice-gw7*xx.dts* devicetrees will not
go away until Jarrko picks up this amendment patch for the dt-bindings:

you might want to split this per sub-architecture perhaps (freescale,
mediatek, rockchip) as such dts changes normally go through the trees
of the subarchitecture maintainers.


For the rockchip-parts itself, I'm also fine with them going through
somewhere else - gru devices are pretty much "finished" by now,
so for the rockchip changes

My concern was that other developers may see these new warnings
and start submitting piecemeal fixes.  That would be a waste
of time since I already prepared fixes for everything weeks ago.
I was only waiting for the schema changes to hit mainline.

I was hoping that these might make it to Linus during the back half
of the merge window so that the warnings are gone by rc1 time
and nobody will ever see them.

Of course I can split them up if that's what Arnd & Olof prefer.

...but I think you should split this per-SoC.

Anyway, if Arnd wants to take this patch directly I'm also totally fine with that.

I would prefer to apply the combined patches:
if you end up with a series of patches that all have
identical commit texts, it's better to combine them
as that gives a more readable git history.

However, I got some conflicts trying to apply them on
top of v6.7, so maybe check that and resend.

This patch needs to be applied on top of the soc-dt-6.8 tag,
not v6.7, because there were changes in your v6.8 pull request
which introduce a new TPM DT node in:

  arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx.dtsi
  arch/arm64/boot/dts/freescale/imx8mp-venice-gw72xx.dtsi

and modify an existing TPM DT node in:

  arch/arm64/boot/dts/freescale/imx8mp-venice-gw74xx.dts

So if I'd base this patch on top of v6.7, it would be missing
the fixes for these three devicetrees and I'd have to submit
a separate patch with them.  Happy to do so if that's what
you want but basing on top of soc-dt-6.8 seemed more reasonable
to me as initial submission.

Thanks!
