Subject[PATCH 0/8] tpm: Add driver for cr50
Date
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 two patches add some sysfs attributes
and make symlinks so that ChromeOS userspace works.
