This is shown with Samsung Chromebook Pro (Caroline) with TPM 1.2
(SLB 9670):

Background
==========
TCG PC Client Platform TPM Profile (PTP) Specification, paragraph 6.1 FIFO
Interface Locality Usage per Register, Table 39 Register Behavior Based on
Locality Setting for FIFO - a read attempt to TPM_STS_x Registers returns
0xFF in case of lack of locality. The described situation manifests itself
with the following warning trace:
The fix
=======
Add the proper decorations to tpm_tis_gen_interrupt() and
tpm_get_timeouts().
I tried that patch (alone on the top of the HEAD of Linus master) and I
still get the same trace in dmesg
Can you give a shot to
git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd.git
It has couple of more fixes, and paste the log.
And if possible a full stack trace :-)
And apply this patch on top. Cannot apply it there before it's reviewed.
I get the following stacktrace with your branch and the patch here:

If I also apply the patch to change the WARN_ONCE in dev_warn_once, and grep
on the string "tpm", I get the following:

No immediate idea why this happens as the code should take locality.
I noticed that the original patch bundles incorrectly two fixes, so I
send mu PT without the current fix and turn into a patch set. Let's
try to debug this for rc2/rc3.
Hey, I'm coming back regarding this issue, I'm running 5.10 (from debian
unstable) and still getting this issue
