I have the same problem with Windows 10 Enterprise running under
qemu-2.5.0-9.fc23.1.tpmfix (which is the qemu version containing the fix
you mentioned above.) on fedora 23. The same qemu version runs windows 7
enterprise with TPM just fine. So there seems to be some change in the
way Windows uses TPM between 7 and 10.

Title:
Windows 10 reports no compatible TPM found yet device manager shows
it?
Status in QEMU:
New
Bug description:
Ubuntu 16.04 with stock kvm, libvirt, ovmf
Qemu 2.5 installed from stock ubuntu ppa
Qemu 2.6.1 built from tarball.
Qemu 2.7.0-rc4 built from tarball.
Windows 10 guest reports a TPM device is installed and the driver
functional under Device Manager-->Security Devices. TPM Administrator
however advises no compatible TPM chip can be found.
Qemu 2.5 is buggy and prevents the guest loading the TPM driver, this
was addressed by
http://git.qemu.org/?p=qemu.git;a=commit;h=2b1c2e8e5f1990f0a201a8cbf9d366fca60f4aa8
Have tested the below cmd out on both qemu-2.6.1 and qemu-2.7.0-rc4,
both suffer the same problem. My TPM is most certainly compatible as
installing Win10Pro onto the same host as bare metal provides me the
desired and expected functionality aka Bitlocker and TPM Administrator
work.
