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).

Properties for an MDIO bus multiplexer found in Broadcom iProc based SoCs.
|
|
|
|
This MDIO bus multiplexer defines buses that could be internal as well as
|
|
external to SoCs and could accept MDIO transaction compatible to C-22 or
|
|
C-45 Clause. When child bus is selected, one needs to select these two
|
|
properties as well to generate desired MDIO transaction on appropriate bus.
|
|
|
|
Required properties in addition to the generic multiplexer properties:
|
|
|
|
MDIO multiplexer node:
|
|
- compatible: brcm,mdio-mux-iproc.
|
|
|
|
Every non-ethernet PHY requires a compatible so that it could be probed based
|
|
on this compatible string.
|
|
|
|
Additional information regarding generic multiplexer properties can be found
|
|
at- Documentation/devicetree/bindings/net/mdio-mux.txt
|
|
|
|
|
|
for example:
|
|
mdio_mux_iproc: mdio-mux@6602023c {
|
|
compatible = "brcm,mdio-mux-iproc";
|
|
reg = <0x6602023c 0x14>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
mdio@0 {
|
|
reg = <0x0>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
pci_phy0: pci-phy@0 {
|
|
compatible = "brcm,ns2-pcie-phy";
|
|
reg = <0x0>;
|
|
#phy-cells = <0>;
|
|
};
|
|
};
|
|
|
|
mdio@7 {
|
|
reg = <0x7>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
pci_phy1: pci-phy@0 {
|
|
compatible = "brcm,ns2-pcie-phy";
|
|
reg = <0x0>;
|
|
#phy-cells = <0>;
|
|
};
|
|
};
|
|
mdio@10 {
|
|
reg = <0x10>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|

gphy0: eth-phy@10 {
