This patch set enables TPM2 protocol and provides drivers for FIFO and CRB interfaces.
Major changes since v1: - Improved struct tpm_chip life-cycle by taking advantage of devres API. - Refined sysfs attributes as simple key-values thereby not repeating mistakes in TPM1 sysfs attributes. - Documented functions in tpm-chip.c and tpm2-cmd.c. - Documented sysfs attributes. Major changes since v2: - Lots of fixes in calling order in device drivers (thanks to Jason Gunthorpe for pointing these out!). - Attach sysfs attributes to the misc device because it represents TPM device to the user space. Major changes since v3: - Disable sysfs attibutes for TPM 2.0 for until we can sort out the best approach for them. - Fixed all the style issues found with checkpatch.pl. Major changes since v4: - missing EXPORT_SYMBOL_GPL() - own class for TPM devices used for TPM 2.0 devices and onwards. Major changes since v5: - Non-racy initialization for sysfs attributes using struct device's groups field. - The class 'tpm' is used now for all TPM devices. For the first device node major MISC_MAJOR and minor TPM_MINOR is used in order to retain backwards compatability.
