-Subject: [PATCH 506/513] net-next: mediatek: add support for rt3050
-
-Add support for SoCs from the rt3050 family. This include rt3050, rt3052,
-rt3352 and rt5350. These all have a builtin 5 port 100mbit switch. This patch
-includes rudimentary code to power up the switch. There are a lot of magic
-values that get written to the switch and the internal phys. These values
-come straight from the SDK driver and we do not know the meaning of most of
-them.
