This module can be found on the Turris Omnia board connected via the I2C interface. Among some cryptographic functions, the chip has a 512 bit One Time Programmable memory, 88 byte configuration memory and 512 byte general purpose memory. The Turris Omnia stores serial number and device MAC address in the OTP memory. This commit adds basic support for reading the EEPROM and also exposes the chips Random Number Generator. The driver is based on code by Josh Datko, Cryptotronix, jbd@cryptotronix.com and also Tomas Hlavacek, CZ.NIC, tomas.hlavacek@nic.cz Signed-off-by: Tomas Hlavacek <tomas.hlavacek@nic.cz> Signed-off-by: Marek Behun <marek.behun@nic.cz> create mode 100644 drivers/misc/atsha204a-i2c.c create mode 100644 include/atsha204a-i2c.h Signed-off-by: Stefan Roese <sr@denx.de>

depends on MISC

help
|

Enable (read-only) access for the e-fuse block found in Rockchip

SoCs: accesses can either be made using byte addressing and a length
|
|
or through child-nodes that are generated based on the e-fuse map
|
|
retrieved from the DTS.
|
|

|
This driver currently supports the RK3399 only, but can easily be
|
|
extended (by porting the read function from the Linux kernel sources)
|
|
to support other recent Rockchip devices.

help
|

Enable command-line access to the Chrome OS EC (Embedded

Controller). This provides the 'crosec' command which has
|
|
a number of sub-commands for performing EC tasks such as
|

updating its flash, accessing a small saved context area
|

and talking to the I2C bus behind the EC (if there is one).

Enable access to the Chrome OS EC. This is a separate

|
microcontroller typically available on a SPI bus on Chromebooks. It
|
|
provides access to the keyboard, some internal storage and may
|
|
control access to the battery and main PMIC depending on the
|

device. You can use the 'crosec' command to access it.

Enable I2C access to the Chrome OS EC. This is used on older
|
|
ARM Chromebooks such as snow and spring before the standard bus
|
|
changed to SPI. The EC will accept commands across the I2C using
|
|
a special message protocol, and provide responses.

Enable I2C access to the Chrome OS EC. This is used on x86
|

Chromebooks such as link and falco. The keyboard is provided
|
|
through a legacy port interface, so on x86 machines the main
|
|
function of the EC is power and thermal management.

Enable a sandbox emulation of the Chrome OS EC. This supports
|
|
keyboard (use the -l flag to enable the LCD), verified boot context,
|

EC flash read/write/erase support and a few other things. It is

|
enough to perform a Chrome OS verified boot on sandbox.

Enable SPI access to the Chrome OS EC. This is used on newer

ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
|
|
provides a faster and more robust interface than I2C but the bugs
|
|
are less interesting.

auxiliary CPU embedded into Tegra to perform power management work,

PMIC I2C bus, etc. This driver provides the core low-level

driver in the Linux kernel.
