As far as I know the 568 has some fixed OTP settings which are used after reset.

Due to the support of the 567 variant it is already supported in the kernel. jb -- Pengutronix e.K. | Juergen Borleis | Steuerwalder Str. 21 | https://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-128 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-9 |
