Subject[PATCH v2 0/6] tpm: Add driver for cr50
This patch series adds support for the the H1 secure microcontroller
running cr50 firmware found on various recent Chromebooks. This driver
is necessary to boot into a ChromeOS userspace environment. It
implements support for several functions, including TPM-like
functionality, and supports SPI and I2C interfaces.

The last time this was series sent looks to be [1]. I've looked over the
patches and review comments and tried to address any feedback that
Andrey didn't address (really minor things like newlines). The first
three patches add a couple pre-requisite core changes so that the
drivers can be merged. The last three patches add the SPI and i2c drivers
along with the DT binding.


Changes from v1:
* Dropped symlink and sysfs patches
* Removed 'is_suspended' bits
* Added new patch to freeze khwrng thread
* Moved binding to google,cr50.txt and added Reviewed-by tag from Rob

Andrey Pronin (4):
tpm_tis_core: add optional max xfer size check
tpm_tis_spi: add max xfer size
dt-bindings: tpm: document properties for cr50
tpm: add driver for cr50 on SPI

Duncan Laurie (1):
