Ah! O.K. Something odd going on with the threading of the patches. 1/3 seems to be last! > Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Andrew

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.
