Motorcomm YT921x is a series of ethernet switches developed by Shanghai
Motorcomm Electronic Technology, including:
- YT9215S / YT9215RB / YT9215SC: 5 GbE phys
- YT9213NB / YT9214NB: 2 GbE phys
- YT9218N / YT9218MB: 8 GbE phys
and up to 2 serdes interfaces.
This patch adds basic support for a working DSA switch.
