Hi Stefan,
I was also looking for the answer on the same question. According to the information regarding the end of sale information, AP7522 would be end of life (EOL) on 30-03-2022. See http://bit.ly/2klBhab
Although the product EOL date is due to 30 March 2022, the End Of Software Maintenance (EOSM) has a different basis and should be considered. According to the EOSM policy, the support for the most of the software components will be ended 12-24 months after the End of Sale date (see http://bit.ly/2BQEGbD). Since AP7522 is end of sale on 15-02-2018, the maintenance for many software components will be ended on 15-03-2020.
Best regards,
Ali
