• aa5eb9a3a   drivers/misc: Add basic support for ATSHA204A Crypto module ... Browse Code »

  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
