Thank you for your understanding!

Both of linux-tpm2(for-peter-v44 branch) and linux-tpmdd(for-james branch)
kernel tree returned same log as follow:

-------------------------
debian@debian:~$ dmesg | grep -i tpm
[    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.3.0-rc4+

[    0.000000] Kernel command line:

[    1.026110] tpm_tis tpm_tis: Unable to request irq: 8 for probe
-------------------------
I ADDed tpm_tis.force=1 to kernel boot command.

At this status, if I run getcapability command of IBM TPM 2.0 TSS, the
machine returns some data.
Additionally, tpm2-util(by jethro G. B) can read vendor/chip name.

However, trousers and tpm-tool return error as follow:
-------------------------
root@debian:/home/debian# /usr/local/sbin/tcsd -f -e
TCSD TDDL ioctl: (25) Inappropriate ioctl for device
TCSD TDDL Falling back to Read/Write device support.
TCSD TCS ERROR: TCS GetCapability failed with result = 0x1e
-------------------------
May I think that Kernel supports TPM 2.0 but TrouSers TSS does not?
