Hi Adrian,
Thinking a bit more about the discussion we were having in
https://github.com/lede-project/source/pull/6 about the ethernet and
switch configuration on the ea8500.
Given that the stock firmware apparently doesn't enable VLAN on the
switch, I suspect that this router actually has a different
configuration than AP148.
AP148: gmac1 (eth0) -> rgmii -> switch port 0
gmac2 (eth1) -> sgmii -> switch port 6
switch ports 1-4-> PHYs on LAN ports
switch port 5 -> PHY on WAN port
Suspected configuration of ea8500:
gmac1 (eth0) -> rgmii -> switch port 0
gmac2 (eth1) -> rmgii -> PHY on WAN port (bypassing the
switch but using the PHY normally connected to swich port 5)
switch ports 1-4-> PHYs on LAN ports
(switch port 5 is then unused)
In that case no vlans would be needed for the standard 1 WAN 1 LAN
configuration.
A bit of a guess on what would be needed in the device tree to handle
this is attached for the gmac and switch parts (but note the ??? in
pinctrl-0 for gmac2, since I'm not sure what to put here, and possibly
an additional block needs to be defined in the pinmux.)
gmac1: ethernet@37200000 {
status = "ok";
phy-mode = "rgmii";
qcom,id = <1>;
pinctrl-0 = <&rgmii2_pins>;
pinctrl-names = "default";
fixed-link {
speed = <1000>;
full-duplex;
};
};
gmac2: ethernet@37400000 {
status = "ok";
phy-mode = "rgmii";
qcom,id = <2>;
pinctrl-0 = ????
pinctrl-names = "default";
fixed-link {
speed = <1000>;
full-duplex;
};
};
phy0: ethernet-phy@0 {
device_type = "ethernet-phy";
reg = <0>;
qca,ar8327-initvals = <
0x00004 0x7600000 /* PAD0_MODE */
