+/**
+ * \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.
