Related, we do have a way of adding code to run when a device is probed (events). Should we look at using that? Is it better or worse than weak functions?

No, the next step here would be to figure out what to do with the GPR register programming, that'd be likely syscon or similar, but that's for another series.
The return is never triggered due to the goto just above it. Drop it. No functional change.

The dm_gpio_free() is never called, because for stm32, the phy_reset_gpio pointer is never valid. This is because only tegra186 ever claims the phy_reset_gpio, all other platforms use the PHY framework to reset the PHY instead. Drop the dm_gpio_free() and dm_gpio_is_valid().

The driver currently only waits for DMA_MODE SWR bit to clear itself. This is insufficient e.g. on i.MX8M Plus, where the MAC must be reset before IOMUX GPR[1] content is latched into the MAC and used. Without the proper reset, the i.MX8M Plus MAC variant does not take the value in IOMUX GPR[1] into account, which makes it impossible e.g. to switch interface mode from RGMII to any other.
Since proper reset is desired in general to put the block into defined state, always assert the DMA_MODE SWR bit before waiting for the bit to clear itself.

The DWMAC clock in i.MX8M Plus were so far configured via ad-hoc architecture code. Replace that with DM clock instead. This way, the driver claims all its required clock, enables and disables them, and even gets the CSR clock rate and sets the TX clock rate, without any need of architecture specific register fiddling. Drop the architecture specific code while at it too.
The adjustment here is modeled after STM32MP15xx clock handling in this driver.

With DM clock support in place, it is easy to add RMII support into the MAC driver. The RMII cannot operate at 1000 Mbps and at 100 and 10 Mbps the clock frequency is 50 MHz and 5 MHz instead of 25 MHz and 2.5 MHz.
The board DT requires the following adjustments to EQoS node: phy-mode = "rmii"; assigned-clock-parents = <&clk IMX8MP_SYS_PLL1_266M>, <&clk IMX8MP_SYS_PLL2_100M>, <&clk IMX8MP_SYS_PLL2_50M>; assigned-clock-rates = <0>, <100000000>, <50000000>;

The FEC ref clock frequency on i.MX8M Mini/Nano/Plus was so far configured via ad-hoc board code. Replace that with DM clock clk_set_rate() instead. This way, the driver claims all its required clock and sets the ref clock rate, without any need of architecture specific register fiddling.
