/**
 * \file psa/crypto_adjust_config_dependencies.h
 * \brief Adjust PSA configuration by resolving some dependencies.
 *
 * This is an internal header. Do not include it directly.
 *
 * See docs/proposed/psa-conditional-inclusion-c.md.
 * If the Mbed TLS implementation of a cryptographic mechanism A depends on a
 * cryptographic mechanism B then if the cryptographic mechanism A is enabled
 * and not accelerated enable B. Note that if A is enabled and accelerated, it
 * is not necessary to enable B for A support.
