This patch set enables TPM2 protocol and provides drivers for FIFO and CRB interfaces. v2: - 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. v3: - 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. v4: - 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. v5: - missing EXPORT_SYMBOL_GPL() - own class for TPM devices used for TPM 2.0 devices and onwards. v6: - 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. v7: - Release device number and free struct tpm_chip memory inside tpm_dev_release callback. - Moved code from tpm-interface.c and tpm_dev.c to tpm-chip.c. Opens: - What we should do with PPI and BIOS log sysfs attributes? Can we associate them with the character device without breaking anything? Can we postpone this issue after this patch set has been pulled?
