Subject: [PATCH v7 00/10] TPM 2.0 support

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?

Jarkko Sakkinen (9):
  tpm: merge duplicate transmit_cmd() functions
  tpm: two-phase chip management functions
  tpm: fix multiple race conditions in tpm_ppi.c
  tpm: rename chip->dev to chip->pdev
  tpm: device class for tpm
  tpm: fix: move sysfs attributes to the correct place.
  tpm: TPM 2.0 baseline support
  tpm: TPM 2.0 CRB Interface
  tpm: TPM 2.0 sysfs attributes

Will Arthur (1):
  tpm: TPM 2.0 FIFO Interface
