Overview

The Smart Card interface TDA8035 driver handles the external interface chip TDA8035 which supports all necessary functions to control the ICC. These functions involve PHY pin initialization, ICC voltage selection and activation, ICC clock generation, ICC card detection, and activation/deactivation sequences.
