The NPCT75x TPM is TIS compatible. It has an I2C and SPI interface.

Add a compatible string for it, and the generic compatible.

I don't understand why you broke this series up and dropped patches.
NAK, these compatibles are not documented.
Cheers,
Conor.

The original series has three patches:
1) Adding compatibility string which I am adding in this series.
2) Adding schema for the TIS I2c devices which is already covered by
Lukas's patch (already merged in linux-next)
https://lore.kernel.org/all/3f56f0a2bb90697a23e83583a21684b75dc7eea2.1701093036.git.lukas@wunner.de/
3) Removing "Infineon,slb9673" from trivial-devices.yaml which is not
done as it is already added in the TPM specific file. I will add it in
my patch. Good catch!
Thanks for the review.
Regards,
Ninad

I have reconfirmed and other two patches are already dropped and merged
by Lukas:
https://lore.kernel.org/all/3f56f0a2bb90697a23e83583a21684b75dc7eea2.1701093036.git.lukas@wunner.de/
This is the only one pending from that series. Please let me know if I
need to do anything else for this patch series.
Regards,
Ninad

Dropping this should be a standalone patch (with a Fixes tag I suppose).
Looking at what got merged:
- description: Generic TPM 2.0 chips conforming to TCG PTP interface
items:
- enum:
- infineon,slb9673
- nuvoton,npct75x
- const: tcg,tpm-tis-i2c
There's no need to add "nuvoton,npct75x" to this driver, since a
fallback to tcg,tpm-tis-i2c is required by the binding. Adding the
generic compatible however makes sense.
If there's a good reason to add it (like existing QEMU releases that do
not have the generic compatible, but claim to have the npct75x) then
please note why we should make an exception in your commit message.
You need not carry the NAK, the motivation behind patch is fine.
Thanks,
Conor.

Make sense. As there is no specific code for npct75x in the driver, I
will remove it.
Thanks for the review.
