No need for status = "okay", it is the default one.
I will remove the regulator in patch v2.

Two SPIs on the same flexcom? It looks to me something is wrong here.
I will use only 1 spi node and pinctrl in patch v2.

Keep pinctrl-X grouped together.
Sure, I will update.

Should any phy/mdio container be placed here? Also, any reason this node is disabled?
The board has no phy.
We will add external phy boards to macb interface and they will be present in dt-overlay.

The only thing about it (FMPOV) is that there might be people expecting the
default bindings to work with every PHY.

I undestand your POV but DTS should describe the hardware. At least, is
there any PHY shipped with the board to be considered the default one?
SAMA5D3 EDS uses the same approach: it defines individual overlays for each
supported ethernet PHYs.
Thank you,
