Subject: [PATCH 0/5] synquacer - wire up Atmel SHA204A as RNG in DT and ACPI mode
Date: Tue, 30 Apr 2019 18:29:04 +0200	[thread overview]
Message-ID: <20190430162910.16771-1-ard.biesheuvel@linaro.org> (raw)

The Socionext SynQuacer based 96boards DeveloperBox platform does not
incorporate a random number generator, but it does have a 96boards low
speed connector which supports extension boards such as the Secure96,
which has a TPM and some crypto accelerators, one of which incorporates
a random number generator.

This series implements support for the RNG part, which is one of several
functions of the Atmel SHA204A I2C crypto accelerator, and wires it up so
both DT and ACPI based boot methods can use the device.

Ard Biesheuvel (5):
  i2c: acpi: permit bus speed to be discovered after enumeration
  crypto: atmel-ecc: add support for ACPI probing on non-AT91 platforms
  crypto: atmel-ecc: factor out code that can be shared
  crypto: atmel-i2c: add support for SHA204A random number generator
  dt-bindings: add Atmel SHA204A I2C crypto processor
