Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

XILINX GMIITORGMII Converter Driver Device Tree Bindings
|
|
--------------------------------------------------------
|
|
|
|
The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media
|
|
Independent Interface (RGMII) core provides the RGMII between RGMII-compliant
|
|
Ethernet physical media devices (PHY) and the Gigabit Ethernet controller.
|
|
This core can be used in all three modes of operation(10/100/1000 Mb/s).
|
|
The Management Data Input/Output (MDIO) interface is used to configure the
|
|
Speed of operation. This core can switch dynamically between the three
|
|
Different speed modes by configuring the conveter register through mdio write.
|
|
|
|
This converter sits between the ethernet MAC and the external phy.
|
|
MAC <==> GMII2RGMII <==> RGMII_PHY
|
|
|
|
For more details about mdio please refer phy.txt file in the same directory.
|
|
|
|
Required properties:
|
|
- compatible : Should be "xlnx,gmii-to-rgmii-1.0"
|
|
- reg : The ID number for the phy, usually a small integer
|
|
- phy-handle : Should point to the external phy device.
|
|
See ethernet.txt file in the same directory.
|
|
|
|
Example:
|
|
mdio {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
phy: ethernet-phy@0 {
|
|
......
|
|
};
|
|
gmiitorgmii: gmiitorgmii@8 {
|
|
compatible = "xlnx,gmii-to-rgmii-1.0";
|
|
reg = <8>;
|
|
phy-handle = <&phy>;
|
|
};
|
|
};
