7 TCG PTP Specification defines two interface types: FIFO and CRB. The former is
11 FIFO (First-In-First-Out) interface is used by the tpm_tis_core dependent
18 tpm_tis comes from the TPM Interface Specification, which is the hardware
19 interface specification for TPM 1.x chips.
21 Communication is based on a 20 KiB buffer shared by the TPM chip through a
23 further split into five equal-size 4 KiB buffers, which provide equivalent
24 sets of registers for communication between the CPU and TPM. These
