Thanks.
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. v2: - update DT binding patches so the SHA204A and ECC508A module bindings are in trivial-devices.yaml. - add acks from Linus and Mika Assuming Rob is ok now with the DT binding patches, can we please take this through the crypto tree?
