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

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

What's the point of the generic compatible if you are adding the device
specific ones to the driver anyway?

Thanks,

I have removed this commit from this patchset and send it as a separate patch.
