[net-next v1 v1 0/5] Add StarFive JHB100 soc SGMII GMAC support

[net-next v1 v1 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

[net-next v1 v1 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 dwmacc 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 v1 v1 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.
