            There are three types of ATECC608A ( Secure Element) chips, which are
            Trust & GO, TrustFLex and Trust Custom. For more details consult README
            file of esp_cryptoauth_utility which is part of esp-cryptoauthlib component.
        config ATECC608A_TNG
            bool "ATECC608A chip type Trust & GO"

        bool "Force use of legacy I2C driver"
        default n
        help
            Enable this option if you're using an I2C device that requires the legacy I2C driver and encounter conflicts related to I2C driver usage.
            This will force the use of the legacy driver for ATECC608A communication.

            For ESP-IDF versions < 5.2: Only the legacy I2C driver is available, so this option has no effect.
            For ESP-IDF versions >= 5.2: New I2C driver is in use by default. Enable this option to switch back to the legacy driver if needed.

    config ATCA_MBEDTLS_ECDSA
        bool "Enable Hardware ECDSA keys for mbedTLS (ESP-IDF 5.x only)"
        depends on MBEDTLS_ECDSA_C
        help
            Enable ATECC608 hardware ECDSA integration with mbedTLS using the
            ALT mechanism. This allows using ATECC private keys for TLS client
            authentication and other ECDSA operations.

            NOTE: This option only works with ESP-IDF 5.x (mbedTLS 3.x).
            For ESP-IDF 6.x+ (mbedTLS 4.x), use CONFIG_MBEDTLS_HARDWARE_ATECC
            in the mbedtls component Kconfig instead.
