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 integrated 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 7.1-rc2

previous patch link:
v2: https://patchwork.kernel.org/project/netdevbpf/cover/20260417024523.107786-1-minda.chen@starfivetech.com/

changes
v3:
patch2: Add jhb100 attach to jh7110 compatibible, remove redundant commit
message. just descript the jhb100 hardware.
patch3: Add oneOf 5 clocks / 6 clocks to claim the clocks and make it
pass yaml test.
patch4: Add review tag and unused tag to phy interface.

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()

Remove jh8100 dt-bindings because do not support it now.
StarFive have stopped jh8100 developing and will not release
it outside.

The jhb100 GMAC still using Synopsys designware GMAC core.
hardware features are similar with jh7100.
Add jhb100 GMAC compatible and reset, interrupts features.
jhb100 dwmac has only one reset signal and one interrupt
line.

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.
So in jhb100 SGMII interface contain 6 clocks, RMII/RGMII
interface still contail 5 clocks.

Add jhb100 compatible and SGMII support. jhb100 soc contains
2 SGMII interfaces and integrated with serdes PHY. SGMII with
split TX/RX MAC clock and need to set 2.5M/25M/125M TX/RX clock
rate in 10M/100M/1000M speed mode.

Why (void *) when it is already a void *?

Why is this not being done in the commit adding the jhb100 in the first
place?

This can just be "maxItems: 5", since minItems is set outside the
conditional to 5.

Remove these constraints, since they don't do anything more than the
outside ones do.

Can't you just leave this list outside the conditional section, and add
the extra item to the end? The only difference appears to be the
sgmii_rx clock, and it's at the end.

I'm also not really convinced that this flexibility is required, unless
there are some controllers on the platform that do not support sgmii.

You've declared compatibility with the jh7110, why do you also need to
add the new comaptible?
