3  * \brief Definitions for all PSA crypto drivers
4  *
5  * This file contains common definitions shared by all PSA crypto drivers.
6  * Do not include it directly: instead, include the header file(s) for
7  * the type(s) of driver that you are implementing. For example, if
8  * you are writing a driver for a chip that provides both a hardware
9  * random generator and an accelerator for some cryptographic algorithms,
10  * include `psa/crypto_entropy_driver.h` and `psa/crypto_accel_driver.h`.
11  *
12  * This file is part of the PSA Crypto Driver Model, containing functions for
13  * driver developers to implement to enable hardware to be called in a
14  * standardized way by a PSA Cryptographic API implementation. The functions
15  * comprising the driver model, which driver authors implement, are not
16  * intended to be called by application developers.
