Hi, I've include "BCM5301X: " in the subject line. See below too.

It'd values are documented in the: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ethernet-controller.yaml In Broadcom's bcmrobo.c we can find: #define PAGE_GPHY_MII_P0 0x10 /* Port0 Internal GPHY MII registers page */ #define PAGE_GPHY_MII_P4 0x14 /* Last/Port4 Internal GPHY MII registers page */ That suggests ports 0, 1, 2, 3 and 4 use internal MII. Does it make "rgmii" a valid value for that? Could we just specify a proper value for all 5 ports in the bcm-ns.dtsi? > port@5 { > reg = <5>; > label = "cpu"; > ethernet = <&gmac0>; > + phy-mode = "internal"; > > fixed-link { > speed = <1000>; > - duplex-full; > + full-duplex; > + pause; > }; > }; > }; Same here: could we specify "phy-mode" and "fixed-link" for ports 5, 7 and 8 in the bcm-ns.dtsi?

From what I remember, the "RGMII" comes simply from the PHY-Chip's datasheet itself. I "think" that it was a BCM50610. (The POE is done by a separate TPS23754 chip). The datasheet ( B50610-DS07-R ) boast the following line in the spec overview: "Supports only RGMII MAC interface" . So by that logic, it can only be RGMII, since it's the only mode the PHY-chip accepts. But let's wait, I see if I can get phytool dump by the weekend, that should tell me the ID. This can be matched with the kernel's broadcom phy driver to tell which PHY-chip it is. > > Could we just specify a proper value for all 5 ports in the bcm-ns.dtsi? > puh, in a dtsi for the whole platform that can stand up to that schema validation? Well, I just ask myself: "What can we really set them to, if like "nothing" is connected? Are they internally unmuxed, pulled-down or maybe even kept floating? don't know...". Is it possible to skip over this question, if all the ports@X are by default all set to ' status = "disabled" ' in the dtsi? And each device's dts has to set the individual status = "okay" property to activate them and then we can expect that the device's dts sets a proper phy-mode setting? (I mean this is a established method that all nodes should follow anyway already?) (don't know if a per-port ' status = "disabled" ' property is evaluated by the switch drivers/dsa though, they might just ignore that) > > port@5 { > > reg = <5>; > > label = "cpu"; > > ethernet = <&gmac0>; > > + phy-mode = "internal"; > > > > fixed-link { > > speed = <1000>; > > - duplex-full; > > + full-duplex; > > + pause; > > }; > > }; > > }; > > Same here: could we specify "phy-mode" and "fixed-link" for ports 5, 7 > and 8 in the bcm-ns.dtsi?

trying to handle that issue... Now in case of the MR26 and MR32 this ethernet switch is a IP-Block inside the SoC right next to the Ethernet-Core. So without any of broadcom's datasheet about this, I would just say that the link between the internal switches MAC (on the "CPU"-port) to the internal ethernet MAC is as "internal as it gets". (i.e. there's no phy there at all, it's the one MAC talking directly to the other MAC and vice versa.) But for real "switches" chips this is an issue too. Recently, I read this explanation in a commit write-up for the rtl8365mb switch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=487994ff75880569d32504d7e70da8b3328e0693 | Since commit a18e6521a7d9 ("net: phylink: handle NA interface mode in | phylink_fwnode_phy_connect()"), phylib defaults to GMII when no phy-mode | or phy-connection-type property is specified in a DSA port node of the | device tree. | [...] | | It should be noted that the aforementioned regression is not because the | blamed commit was incorrect: on the contrary, the blamed commit is | correcting the previous behaviour whereby unspecified phy-mode would | cause the internal interface mode to be PHY_INTERFACE_MODE_NA. The | rtl8365mb driver only worked by accident before because it _did_ | advertise support for PHY_INTERFACE_MODE_NA, despite NA being reserved | for internal use by phylink. With one mistake fixed, the other was exposed. (In a way, phylib's default (whatever they currently are) could be the answer to that decision?) Cheers, Christian

fixes the "duplex-full" typo, adds phy-modes for the internal switch and the PHY-chip. This also includs adding pause support for the internal cpu port.
