This is the driver for TPM chip from ST Microelectronics.
If you have a TPM security chip from STMicroelectronics working with
an I2C, in menuconfig or .config choose the tpm driver on
device --> tpm and activate the protocol of your choice before compiling
the kernel.
The driver will be accessible from within Linux.

The TPM will respond to TPM_GET_CAP with TPM_ERR_INVALID_POSTINIT if
TPM_STARTUP has not been issued. Detect this and automatically
issue TPM_STARTUP.
This is for embedded applications where the kernel is the first thing
to touch the TPM.

This patch changes the semantics of the duration calculation for an
ordinal, by masking out the higher bits of a tpm command, which specify
whether it's an TPM_PROTECTED_COMMAND, TPM_UNPROTECTED_COMMAND,
TPM_CONNECTION_COMMAND, TPM_CONNECTION_COMMAND, TPM_VENDOR_COMMAND.
(See TPM Main Spec Part 2 Section 17 for details).
For all TPM_PROTECTED and TPM_CONNECTION commands the results are
unchanged.
The TPM_UNPROTECTED commands are TSS commands and thus irrelevant as
they are not sent to the tpm.
For vendor commands the semantics change for ordinals 10 and 11 but
they were probably wrong anyway.
For everything else which has the ordinal set to 10 or 11 the semantics
change as it now uses TPM_UNDEFINED instead of TPM_SHORT which was
probably wrong anyway (but irrelevant as not defined by the standard).
This patch also gets rid of the (false positive) smatch warning:
drivers/char/tpm/tpm.c:360 tpm_calc_ordinal_duration() error: buffer
overflow 'tpm_protected_ordinal_duration' 12 <= 243

The entries in tpm_protected_ordinal_duration are exactly the same as
the first 12 in tpm_ordinal_duration, so we can simply remove this one,
and save some bytes.
This does not change the behavior of the driver.

There's a slightly non-trivial merge in virtio-net, as we cleaned up the
virtio add_buf interface while DaveM accepted the mq virtio-net patches.
You can see my solution in my pending-rebases branch, if that helps, but I
know you love merging:

Here is the "big" char/misc driver patches for 3.8-rc1. I'm starting to
put random driver subsystems that I had previously sent you through the
driver-core tree in this tree, as it makes more sense to do so.
Nothing major here, the various __dev* removals, some mei driver
updates, and other random driver-specific things from the different
maintainers and developers.
Note, some MFD drivers got added through this tree, and they are also
coming in through the "real" MFD tree as well, due to some major
mis-communication between me and the different developers. If you have
any merge conflicts, take the ones from the MFD tree, not these ones,
sorry about that.

Merge tag 'char-misc-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull Char/Misc driver merge from Greg Kroah-Hartman:
"Here is the "big" char/misc driver patches for 3.8-rc1. I'm starting
to put random driver subsystems that I had previously sent you through
the driver-core tree in this tree, as it makes more sense to do so.
Nothing major here, the various __dev* removals, some mei driver
updates, and other random driver-specific things from the different
maintainers and developers.
Note, some MFD drivers got added through this tree, and they are also
coming in through the "real" MFD tree as well, due to some major
mis-communication between me and the different developers. If you
have any merge conflicts, take the ones from the MFD tree, not these
ones, sorry about that.

Here's the large driver core updates for 3.8-rc1.
The biggest thing here is the various __dev* marking removals. This is
going to be a pain for the merge with different subsystem trees, I know,
but all of the patches included here have been ACKed by their various
subsystem maintainers, as they wanted them to go through here.
If this is too much of a pain, I can pull all of them out of this tree
and just send you one with the other fixes/updates and then, after
3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
it's up to you. The merges should all be trivial, and Stephen has been
doing them all in linux-next for a few weeks now quite easily.
Other than the __dev* marking removals, there's nothing major here, some
firmware loading updates and other minor things in the driver core.
All of these have (much to Stephen's annoyance), been in linux-next for
a while.

Merge 'block-dev' branch.
I was going to just mark everything here for stable and leave it to the
3.8 merge window, but having decided on doing another -rc, I migth as
well merge it now.
This removes the bd_block_size_semaphore semaphore that was added in
this release to fix a race condition between block size changes and
block IO, and replaces it with atomicity guaratees in fs/buffer.c
instead, along with simplifying fs/block-dev.c.
This removes more lines than it adds, makes the code generally simpler,
and avoids the latency/rt issues that the block size semaphore
introduced for mount.
I'm not happy with the timing, but it wouldn't be much better doing this
during the merge window and then having some delayed back-port of it
into stable.
* block-dev:
blkdev_max_block: make private to fs/buffer.c
direct-io: don't read inode->i_blkbits multiple times
blockdev: remove bd_block_size_semaphore again
fs/buffer.c: make block-size be per-page and protected by the page lock
This reverts the block-device direct access code to the previous
unlocked code, now that fs/buffer.c no longer needs external locking.
With this, fs/block_dev.c is back to the original version, apart from a
whitespace cleanup that I didn't want to revert.

After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.
To be sure, the TTY buffers (and later some stuff) are gone along with
the tty_port, we have to call tty_port_destroy at tear-down places.
This is mostly where the structure containing a tty_port is freed.
This patch does exactly that -- put tty_port_destroy at those places.

As a quick hack we make the old intel_gtt structure mutable so we can
fool a bunch of the existing code which depends on elements in that data
structure. We can/should try to remove this in a subsequent patch.
This should preserve the old gtt init behavior which upon writing these
patches seems incorrect. The next patch will fix these things.
The one exception is VLV which doesn't have the preserved flush control
write behavior. Since we want to do that for all GEN6+ stuff, we'll
handle that in a later patch. Mainstream VLV support doesn't actually
exist yet anyway.

The value stored in last_data must be primed for FIPS 140-2 purposes. Upon
first use, either on system startup or after an RNDCLEARPOOL ioctl, we
need to take an initial random sample, store it internally in last_data,
then pass along the value after that to the requester, so that consistency
checks aren't being run against stale and possibly known data.

This moves the MTU timer driver from arch/arm/plat-nomadik
to drivers/clocksource and moves the header file to the
platform_data directory.
As this moves the last file being compiled to an object out
of arch/arm/plat-nomadik, we have to "turn off the light"
and delete the plat-nomadik directory, because it is not
allowed to have an empty Makefile in a plat-* directory.
This is probably also a desired side effect of depopulating
the arch/arm directory of drivers. Luckily we have just
deleted all the <plat/*> include files prior to this so
by moving the last one we may delete the directory.
After this all the Ux500 and Nomadik device drivers live
outside of the arch/arm hierarchy.
