dt-bindings: net: Add Lynx PCS binding

2022-10-19T12:25:09Z

This binding is fairly bare-bones for now, since the Lynx driver doesn't parse any properties (or match based on the compatible). We just need it in order to prevent the PCS nodes from having phy devices attached to them. This is not really a problem, but it is a bit inefficient. This binding is really for three separate PCSs (SGMII, QSGMII, and XFI). However, the driver treats all of them the same. This works because the SGMII and XFI devices typically use the same address, and the SerDes driver (or RCW) muxes between them. The QSGMII PCSs have the same register layout as the SGMII PCSs. To do things properly, we'd probably do something like ethernet-pcs@0 { #pcs-cells = <1>; compatible = "fsl,lynx-pcs"; reg = <0>, <1>, <2>, <3>; }; but that would add complexity, and we can describe the hardware just fine using separate PCSs for now.

dt-bindings: net: pcs: add bindings for Renesas RZ/N1 MII converter

2022-06-29T14:08:06Z

This MII converter can be found on the RZ/N1 processor family. The MII converter ports are declared as subnodes which are then referenced by users of the PCS driver such as the switch.
