This series adds driver model support for Trusted Platform Modules (TPMs).
These have a very simple interface and are configured via the device tree.
Two bus types are supported at present: I2C and LPC (Intel Low-Pin-Count).
Most drivers and users are converted over to driver model. The exception is
the Atmel TPM and its users.
The I2C driver has been cleaned up and simplified. It was ported from Linux
and was pretty hard to follow. This series includes patches to unify the
code, remove duplicated data structures and drop unnecessary indirection.
Also this series enables the TPM on all Chromebooks (snow, spring, nyan-big,
pit, pi, link) since some did not have it fully enabled.
As before, the 'tpm' command can be used to implement TPM functionality.
