Subject: [PATCH net-next 0/3] riscv: spacemit: Add ethernet support for K3

Add initial support for ethernet controller of the Spacemit K3 SoC.
This ethernet controller is almost a standard Synopsys DesignWare
MAC (version 5.40a). This controller require a syscon device to
configure some basic features, like interface type and internal delay.

Inochi Amaoto (3):
  dt-bindings: net: Add support for Spacemit K3 dwmac
  net: stmmac: platform: Add snps,dwmac-5.40a IP compatible string
  net: stmmac: Add glue layer for Spacemit K3 SoC
