Subject: [PATCH v2 0/6] tpm: Add driver for cr50
Date: Tue, 16 Jul 2019 15:45:12 -0700 [thread overview]
Message-ID: <20190716224518.62556-1-swboyd@chromium.org> (raw)
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.
