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).

Common MDIO bus properties.
|
|
|
|
These are generic properties that can apply to any MDIO bus.
|
|
|
|
Optional properties:
|
|
- reset-gpios: One GPIO that control the RESET lines of all PHYs on that MDIO
|
|
bus.
|
|
- reset-delay-us: RESET pulse width in microseconds.
|
|
|
|
A list of child nodes, one per device on the bus is expected. These
|
|
should follow the generic phy.txt, or a device specific binding document.
|
|
|
|
The 'reset-delay-us' indicates the RESET signal pulse width in microseconds and
|
|
applies to all PHY devices. It must therefore be appropriately determined based
|
|
on all PHY requirements (maximum value of all per-PHY RESET pulse widths).
|
|
|
|
Example :
|
|
This example shows these optional properties, plus other properties
|
|
required for the TI Davinci MDIO driver.
|
|
|
|
davinci_mdio: ethernet@0x5c030000 {
|
|
compatible = "ti,davinci_mdio";
|
|
reg = <0x5c030000 0x1000>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;
|
|
reset-delay-us = <2>;
|
|

|
ethphy0: ethernet-phy@1 {
|
|
reg = <1>;

};

ethphy1: ethernet-phy@3 {

reg = <3>;
