[v2] Add motorcomm 8531s set ds func and 8522 driver

[net-next v2 0/3] Add motorcomm 8531s set ds func and 8522 driver

Posted by Minda Chen 1 month, 4 weeks ago

This patch is for Starfive JHB100 EVB board. JHB100  contain
1 RGMII/RMII and 1 RMII synopsys GMAC cores. In the EVB board, RGMII
interface connect with YT8531s Ethernet PHY. RMII interface connect
with YT8522 ethernet PHY. So patch 1-2 is for RGMII interface
patch 3 is RMII is for RMII interface.

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/

The patch base in V7.0-rc5

The change list:
v2:
1. patch1 move mdio lock out from  yt8531_set_ds().
2. patch2 changed to phy_interface_is_rgmii().
