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.
All of this has been in linux-next for a while.

Fix up trivial conflict in drivers/mmc/host/Kconfig due to new drivers
having been added (both at the end, as usual..)

This patch adds a driver to support Infineon's SLB 9635 TT 1.2 Soft I2C TPMs
which follow the TGC TIS 1.2 TPM specification[1] and Infineon's I2C Protocol
Stack Specification 0.20.
The I2C Protocol Stack Specification is a simple adaption of the LPC TIS
Protocol to the I2C Bus.
The I2C TPMs can be used when LPC Bus is not available (i.e. non x86
architectures like ARM).
The driver is based on the tpm_tis.c driver by Leendert van Dorn and Kyleen
Hall and has quite similar functionality.
Tested on Nvidia ARM Tegra2 Development Platform and Beagleboard (ARM OMAP)
Tested with the Trousers[2] TSS API Testsuite v 0.3 [3]
Compile-tested on x86 (32/64-bit)
Updates since version 2.1.4:
- included "Lock the I2C adapter for a sequence of requests", by Bryan Freed
- use __i2c_transfer instead of own implementation of unlocked i2c_transfer
- use struct dev_pm_ops for power management via SIMPLE_DEV_PM_OPS
Updates since version 2.1.3:
- use proper probing mechanism
* either add the tpm using I2C_BOARD_INFO to your board file or probe it
* during runtime e.g on BeagleBoard using :
* "echo tpm_i2c_infineon 0x20 > /sys/bus/i2c/devices/i2c-2/new_device"
- fix possible endless loop if hardware misbehaves
- improved return codes
- consistent spelling i2c/tpm -> I2C/TPM
- remove hardcoded sleep values and msleep usage
- removed debug statements
- added check for I2C functionality
- renaming to tpm_i2c_infineon
Updates since version 2.1.2:
- added sysfs entries for duration and timeouts
- updated to new tpm_do_selftest
Updates since version 2.1.0:
- improved error handling
- implemented workarounds needed by the tpm
- fixed typos
