3872d25bd384f7e Lukas Wunner 2023-09-23 13 The Infineon SLB9670 Trusted Platform Module requires a specific reset
3872d25bd384f7e Lukas Wunner 2023-09-23 14 sequence on its RST# pin which is documented in sections 5.4 and 5.5 of
3872d25bd384f7e Lukas Wunner 2023-09-23 15 the datasheet [1]. This driver performs the reset sequence using a GPIO.
