linux.git/include/linux/tpm_ptp.h, branch master Linux kernel source tree tpm: Move platform specific definitions to the new PTP header 2026-08-25T15:13:35+00:00 Ross Philipson ross.philipson@gmail.com 2026-07-11T16:01:05+00:00 5467ade151973477742af922cc33bb30e816af42 These are definitions for TPM 2.0 interface and interactions with the platform as defined in the TCG specification: These definitions are located here in a separate file to avoid conflicts with vendor specific TIS/FIFO definition (e.g. STMicroelectronics, Infineon Technologies, etc). This allows the TCG defined TIS/FIFO interface to be in a public header while the former chip specific implementations contain their own definitions. TPM 1.x family chips that adhere to the TCG specifications use the TIS/FIFO interface as defined here.
