Subject: [PATCH] ARM: dts: Add ethernet to a bunch of platforms
|
|
|
|
These platforms have the PHY defined already so we just
|
|
need to add a single device node to each of them to activate
|
|
the ethernet device.
|
|
|
|
The PHY skew/delay settings for pin control is known from a
|
|
few vendor trees and old OpenWRT patch sets.
|
|
|
|
This is a modified version of upstream commit
|
|
95220046a62c00b5afb1aa7c1971989d427db977,
|
|
just dropping the NAS4220B changes.
