[net-next v2 0/5] Add StarFive JHB100 soc SGMII GMAC support

[net-next v2 0/5] Add StarFive JHB100 soc SGMII GMAC support

[Minda Chen]

JHB100 is a Starfive new RISC-V SoC for datacenter BMC (BaseBoard
Managent Controller). Similar with Aspeed 27x0.

The JHB100 minimal system upstream is in progress:
https://patchwork.kernel.org/project/linux-riscv/cover/20260403054945.467700-1-changhuang.liang@starfivetech.com/

JHB100 GMAC still using designware GMAC core like JH7100 and JH7110,
and contains 2 SGMII interfaces, 1 RGMII/RMII interface, 1 RMII
interface. In JH7100/JH7110 dwmac-starfive.c have supported RGMII/RMII
interface. So require to add SGMII support to dwmac-starfive.c for JHB100.

SGMII serdes PHY has been intergrated in JHB100 and do not have driver
setting.

In JHB100 EVB board, SGMII connect with motorcomm YT8531s external PHY
and support RJ45 ethernet port.

The patch base in 7.0-rc5

changes
v2:
1. patch1 Add the remove reason
2. patch2 rename rx clock to sgmii_rx
3. patch4 confirm sgmii rx clock exist, or will probe error
   sgmii will not call starfive_dwmac_set_mode()

[net-next v2 1/5] dt-bindings: net: starfive,jh7110-dwmac: Remove JH8100

[Minda Chen]

Remove JH8100 dt-bindings because do not support it now.
StarFive have stopped JH8100 developing and will release it
outside.

Is there a missing "not" in that sentence?

[net-next v2 2/5] dt-bindings: net: starfive,jh7110-dwmac: Add JHB100 support

[Minda Chen]

Add StarFive JHB100 dwmac support and compatible.
The JHB100 dwmac shares the same driver code as the JH7110 dwmac,
which contains 2 SGMII interfaces, 1 RGMII/RMII interface and
1 RMII interface.
JHB100 dwmac has only one reset signal and one main interrupt
line.

Please refer to below:

JHB100: reset-names = "stmmaceth";

Example usage of JHB100 in the device tree:

gmac0: ethernet@11b80000 {
        compatible = "starfive,jhb100-dwmac",
                     "snps,dwmac-5.20";
        interrupts = <225>;
        interrupt-names = "macirq";
        ...
};

[net-next v2 3/5] dt-bindings: net: starfive,jh7110-dwmac: Add JHB100 sgmii rx clk

[Minda Chen]

JHB100 SGMII interface tx/rx mac clock is split and require to
set clock rate in 10M/100M/1000M speed. So dts need to add a
new rx clock in code, dts and dt binding doc.

My bot found errors running 'make dt_binding_check' on your patch:

./Documentation/devicetree/bindings/net/starfive,jh7110-dwmac.yaml:56:8: [warning] wrong indentation: expected 8 but found 7 (indentation)

See https://patchwork.kernel.org/project/devicetree/patch/20260417024523.107786-4-minda.chen@starfivetech.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

phy_interface_t interface is likely unused in stmmac_starfive_sgmii_set_clk_rate → may need __maybe_unused or (void)interface to avoid -Werror=unused-parameter on strict builds.
