I'm still not convinced you got this right, the document you cite only
seems to mention TPM 1.2 as the base for TIS 1.3, but not TPM 1.3.

You are right, I was careless, thanks for your reply.
Thanks and best,

The TPM version number in the help message is wrong, which will
cause confusion. This patch fixes it.

If you have a TPM security chip which is connected to a regular,
non-tcg SPI master (i.e. most embedded platforms) that is compliant with the
- TCG TIS 1.3 TPM specification (TPM1.2) or the TCG PTP FIFO
+ TCG TIS 1.3 TPM specification (TPM1.3) or the TCG PTP FIFO
specification (TPM2.0) say Yes and it will be accessible from
within Linux. To compile this driver as a module, choose M here;
the module will be called tpm_tis_spi.
