[PATCH] Documentation: devicetree: Add PHY no lane swap binding

From: Lukasz Majewski
Date: Sat Feb 04 2017 - 10:48:51 EST


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.
