Alexander Steffen bbc23a07b0 tpm: Add tpm_tis_i2c backend for tpm_tis_core ... Implement the TCG I2C Interface driver, as specified in the TCG PC Client Platform TPM Profile (PTP) specification for TPM 2.0 v1.04 revision 14, section 8, I2C Interface Definition. This driver supports Guard Times. That is, if required by the TPM, the driver has to wait by a vendor-specific time after each I2C read/write. The specific time is read from the TPM_I2C_INTERFACE_CAPABILITY register. Unfortunately, the TCG specified almost but not quite compatible register addresses. Therefore, the TIS register addresses need to be mapped to I2C ones. The locality is stripped because for now, only locality 0 is supported. Add a sanity check to I2C reads of e.g. TPM_ACCESS and TPM_STS. This is to detect communication errors and issues due to non-standard behaviour (E.g. the clock stretching quirk in the BCM2835, see 4dbfb5f440). In case the sanity check fails, attempt a retry.
