Subject: [GIT PULL] tpmdd updates for Linux 4.8
James,
This patch set contains two new major features:
* Multi-instance TPM proxy driver
* Rework of sharing common TIS code with different physical interfaces.
In addition, there are a vast number of small fixes and cleanups.
/Jarkko
Multi-instance TPM proxy driver
===============================
Using an ioctl on the provided /dev/vtpmx, a client-side vTPM device and
a server side file descriptor is created. The file descriptor must be
passed to a TPM emulator. The device driver will initialize the emulated
TPM using TPM 1.2 or TPM 2 startup commands and it will read the command
durations from the device in case of a TPM 1.2. The choice of emulated
TPM device (1.2 or 2) must be provided with a flag in the ioctl.
Rework of sharing common TIS code with different physical interfaces
====================================================================
There is a new common tpm_tis_core module that contains the core TIS
interface and a callback API for sharing the behavior between different
physical layers like LPC, SPI and I2C. For the 4.8 release adaptations
for standard TCG MMIO and SPI have been provided.
The following changes since commit 26703c636c1f3272b39bd0f6d04d2e970984f1b6:
