i.MX7 Sabre HSIC interface

Hello,

We are working with i.MX7 Sabre evaluation board kernel version 4.9.88 (based on Yocto core-image-base) connected to MicroChip LAN7930-EVB evaluation board by HSIC interface. We do not see activity on HSIC signals: both DATA and STROBE are low. We would appreciate instructions to activate HSIC interface. Do we need to upgrade DTS, compile drivers to kernel? Should HSIC be enabled in uboot and how?

Thank you very much.

Anton.
