Subject: [PATCH v3 0/2] tpm: add driver for cr50 on SPI
Date: Wed, 27 Jul 2016 21:25:15 -0700 [thread overview]
Message-ID: <1469679917-120240-1-git-send-email-apronin@chromium.org> (raw)
In-Reply-To: <1468549218-19215-1-git-send-email-apronin@chromium.org>
In-Reply-To: <1468549218-19215-1-git-send-email-apronin@chromium.org>
This patchset adds support for H1 Secure Microcontroller running
Cr50 firmware. It implements several functions, including TPM-like
functionality, and communicates over SPI using the FIFO protocol
described in the PTP Spec, section 6.
H1 is a proprietary chip that the Chrome OS team is investigating
for inclusion in future Chromebooks.
Depends on the following patchset:
- tpm_tis_core: add optional max xfer size check
v2: Removed driver-specific sysfs attributes.
Compatible id changed to cr50 from cr50_spi.
Updated descriptions of the supported device/interface.
v3: Fixed potential race-condition with last_access_jiffies.
Started using tx_buf/rx_buf in cr50_spi_phy to avoid
potential problems with DMA.
Removed DT properties for fw timing parameters.
Fixed style.
