Subject: [PATCH RFC net-next 0/4] Add the dwmac driver support for T-HEAD
 TH1520 SoC.

I am marking this as an RFC since it has been almost a year since the
previous series and Jisheng has handed it off to me. There was
discussion about the syscon for the APB registers in Jisheng's v2. I've
gone a different route and switched to adding a second memory region to
the gmac node:

  dwmac: DesignWare GMAC IP core registers
    apb: GMAC APB registers

This patch depends my clock controller series:

 [PATCH v3 0/7] clk: thead: Add support for TH1520 AP_SUBSYS clock controller
 https://lore.kernel.org/linux-riscv/20240711-th1520-clk-v3-0-6ff17bb318fb@tenstorrent.com/

and the pinctrl series from Emil:

 [PATCH v2 0/8] Add T-Head TH1520 SoC pin control
 https://lore.kernel.org/linux-riscv/20240103132852.298964-1-emil.renner.berthing@canonical.com

I have a branch with this series and the dependencies on top of 6.10-rc7:
 https://github.com/pdp7/linux/tree/b4/thead-dwmac

Changes since Jisheng v2:
 - remove thead,gmacapb that references syscon for APB registers
 - add a second memory region to gmac nodes for the APB registers
 - Link: https://lore.kernel.org/all/20230827091710.1483-1-jszhang@kernel.org/

Changes since Jisheng v1:
 - rebase on the lastest net-next
 - collect Reviewed-by tag
 - address Krzysztof's comment of the dt binding
 - fix "div is not initialised" issue pointed out by Simon
 - Link: https://lore.kernel.org/all/20230820120213.2054-1-jszhang@kernel.org/
