SPI config for the SPI-NOR is incorrect and completely breaking
reading/writing to the onboard SPI-NOR.
SPI-NOR is connected in the single(x1) IO mode and not in the quad
(x4) mode.
Also, there is no need to override the max frequency from the DTSI
as the mx25u3235f that is used supports 104Mhz.

Both the Topaz switch and 88E1512 PHY have their reset and interrupts
connected to the SoC.
So, define the Topaz and 88E1512 reset pins in the DTS.
Defining the interrupt pins wont work as both the 88E1512 and the
Topaz switch uses active LOW IRQ signals but the A37xx GPIO controller
only supports edge triggers.
88E1512 would require special setup anyway as its INT pin is shared with
the LED2 and you first need to configure it as INT.

Are reset pins connected only on ultra variant? Or on all espressobin
variants? Because if they are on all variants then definitions should go
into common dtsi file.
I see that "gpionb 2" is on v7 variant connected to LED2. So I'm not
sure if this one gpio is also shared or not.

Do you plan to finish also this additional setup?

As far as I know only Ultra has the reset pins connected, on the v5 and v7 Topaz
reset is tied to the system reset so it's not controllable.
I checked both the v5 and v7 schematics and it's like that.

Yes as the MOCHAbin board that I have sent the DTS for also has it connected
so I can use it as Armada 7040 supports level triggers, unlike the A3720.
It's in the queue but as a low priority, so I don't know when will I get to it.

I have WIP patch for A37xx gpio/pinctrl driver which adds support for
level interrupts. I think you would need it for testing...

Espressobin Ultra has a front panel USB3.0 Type-A port which works
just fine so enable it.
I dont see a reason why it was disabled in the first place anyway.

If USB 3.0 port is was tested and is working fine, then what about
adding Fixes: tag into commit message?

Sure, gotta send a v4 anyway dropping the first patch.

This code is duplication of common espressobin code from
armada-3720-espressobin.dtsi file:
