| Message-ID | <t86vM-6Us-5@gated-at.bofh.it> |
Add the documentation to avoid PHY lane swapping. This is a boolean entry to notify the phy device drivers that the TX/RX lanes NO need to be swapped. The use case for this binding mostly happens after wrong HW configuration of PHY IC during bootstrap.

Ah! O.K. Something odd going on with the threading of the patches. 1/3
seems to be last!
