/**
 * \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.
