Re: [PATCH v1 2/3] ARM: MR26: fix dt schema violations

Hi,

I've include "BCM5301X: " in the subject line.

See below too.

On 3.06.2023 16:16, Christian Lamparter wrote:
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. Furthermore, both erronous unit properties
in the gpio-keys node are removed (#size-cells, #address-cells don't
belong here).

It was never clear to me how to exactly specify "phy-mode".

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? There are more devices with warnings:
