Move tpm_vendor_specific data related to TCG PTP specification to tpm_chip. All those fields are directly linked with well known concepts defined in the following chapters common to every TCG tpms. timeout: See see 5.5.1.4 Timeouts duration: See 5.5.1.3 Command Duration Also they are used in TPM drivers (tpm_i2c_atmel, tpm_i2c_infineon, tpm_i2c_nuvoton, tpm_tis and xen-tpmfront) as well as in TPM core files (tpm-sysfs, tpm-interface and tpm2-cmd).
