This is the driver for TPM chip from ST Microelectronics.
If you have a TPM security chip from STMicroelectronics working with
an I2C, in menuconfig or .config choose the tpm driver on
device --> tpm and activate the protocol of your choice before compiling
the kernel.
The driver will be accessible from within Linux.
Tested on linux x86/x64 on kernel 3.x
