Its NETC integration differs from i.MX95 and i.MX94 in the following ways: - there are two standalone ENETCs and no switch: ENETC 0 on PCIe bus 0 (RMII/RGMII) and ENETC 1 on PCIe bus 1 (RMII/RGMII/SGMII), plus a single IEEE 1588 timer; - the NETC system clock is 133 MHz instead of 333 MHz; - the reset value of the ENETC 0 Tx byte credit registers is too small for jumbo frames. The DTS patch set will be sent separately after this series is applied.
