[PATCH v3 0/3] ramips: mt7621-dts: fix dtc warning, links and pinctrl

[Arınç ÜNAL]

Hey everyone,

With this patch series:
- Fix dtc warning on switch at 1f node
- Enable flow control on port at 6 node to match the other side, GMAC0.
- Add pinctrl properties on ethernet node on the mt7621.dtsi. Overwrite
pinctrl-0 property without rgmii2_pins on devicetrees which use the rgmii2
pins as GPIO (22 - 33). Add rgmii2 pin group to gpio function on
mt7621_tplink_archer-x6-v3.dtsi which uses GPIO 28.

Now that pinctrl properties are properly defined on the ethernet node,
GMAC1 will start working.

The third patch opens the path to mux PHY 0 or 4 (usually one of it is a
wan port) directly to the second GMAC of the SoC. In a future patch, this
can be done on the majority of the devicetrees to give the wan port its
dedicated 1 Gbps link. I might do that once this series is applied.

Traffic flow on GMAC1 was tested on an mt7621a board with these modes:
External phy <-> GMAC1
PHY 0/4 <-> GMAC1

RGMII2 pins which are used as GPIO on some devicetrees were tested on a
TP-Link RE650 v1.

Cheers.

v3: Send with less recipients and add Sungbo Eo’s Tested-by tag on the
second patch.

v2: Overwrite pinctrl-0 property for devicetrees which give gpio function
to the rgmii2 pin group.
