[PATCH v5 3/4] MAINTAINERS: Add entry for ULTRATRONIK BOARD SUPPORT

[Goran Rađenović]

Add a new MAINTAINERS section for the ULTRATRONIK BOARD SUPPORT, covering
the stm32mp157c-ultra-fly-sbc.dts board support file.

This ensures that maintainers of this board are properly listed and can be
notified for any relevant changes.

[PATCH v5 4/4] ARM: dts: stm32: add initial support for stm32mp157-ultra-fly-sbc board

[Goran Rađenović]

Add support for Ultratronik's stm32mp157c fly board. This board embeds
a STM32MP157c SOC and 1GB of DDR3. Several connections are available on
this boards: 2*USB2.0, 1*USB2.0 MiniUSB, Debug UART, 1*UART, 1*USART,
SDcard, RJ45, ...

This patch enables basic support for a kernel boot - SD-card or eMMC.

max-speed is probably pointless, rgmii cannot do more than 1G.

PHY interrupts are 99% time level, not edge.

Agreed. I'll drop the `max-speed` property in the next revision.

That is correct, but I am facing strange behavior, when I set 
IRQ_TYPE_LEVEL_LOW.
My board stops booting at:

I must investigate this. If You have any idea, You are welcome to share it.

Could be an interrupt storm. The interrupt is not getting cleared
because of something missing in the PHY driver, so it just fires again
and again.

After a brief investigation, I tend to agree with your assessment that 
the issue lies in the driver—likely the stmmac driver — which is outside 
the scope of my changes.

Therefore, I would suggest keeping IRQ_TYPE_EDGE_FALLING for now, or 
alternatively not using a hardware IRQ at all and falling back to 
polling, as done in stm32mp15xx-dkx.dtsi.

Best regards,
Goran

Since edge is wrong, please use polling.

No, the mdio node is driven by stmmac driver. The issue was maybe more 
linked between pinctrl driver / exti driver where the level trigger is 
probably not well managed (gpio is level but exti driver manage edge 
interrupt). When saw those defering probes, EXTI drivers and pinctrl 
drivers were well probed ?
