/**
* \file psa/crypto_driver_common.h
* \brief Definitions for all PSA crypto drivers
*
* This file contains common definitions shared by all PSA crypto drivers.
* Do not include it directly: instead, include the header file(s) for
* the type(s) of driver that you are implementing. For example, if
* you are writing a dynamically registered driver for a secure element,
* include `psa/crypto_se_driver.h`.
*
* This file is part of the PSA Crypto Driver Model, containing functions for
* driver developers to implement to enable hardware to be called in a
* standardized way by a PSA Cryptographic API implementation. The functions
* comprising the driver model, which driver authors implement, are not
* intended to be called by application developers.
