tpm: seal/unseal for TPM 2.0

2015-10-18T23:01:21Z

Added tpm_trusted_seal() and tpm_trusted_unseal() API for sealing trusted keys. This patch implements basic sealing and unsealing functionality for TPM 2.0: * Seal with a parent key using a 20 byte auth value. * Unseal with a parent key using a 20 byte auth value.

tpm: Provide a generic means to override the chip returned timeouts

2014-07-29T21:10:56Z

Some Atmel TPMs provide completely wrong timeouts from their TPM_CAP_PROP_TIS_TIMEOUT query. This patch detects that and returns new correct values via a DID/VID table in the TIS driver. Tested on ARM using an AT97SC3204T FW version 37.16 Cc: [PHuewe: without this fix these 'broken' Atmel TPMs won't function on older kernels] Signed-off-by: "Berg, Christopher" Signed-off-by: Jason Gunthorpe Signed-off-by: Peter Huewe

tpm: Create a tpm_class_ops structure and use it in the drivers

2014-01-06T13:37:25Z

This replaces the static initialization of a tpm_vendor_specific structure in the drivers with the standard Linux idiom of providing a const structure of function pointers.

tpm: Move tpm_get_random api into the TPM device driver

2012-08-22T16:11:33Z

Move the tpm_get_random api from the trusted keys code into the TPM device driver itself so that other callers can make use of it. Also, change the api slightly so that the number of bytes read is returned in the call, since the TPM command can potentially return fewer bytes than requested.
