Changes in v4 (Laurent):

        - Aligned the pinctrl group values with each other

Changes in v3 (Laurent):

    - Added IOB copyright notice
    - Removed the eth node for the connector that's on the separate I/O
    board
    - Re-ordered some pinctrl groups so they're alphabetical

Changes in v2:

    - Fixed the interrupt flag for i2c1/pmic@25
    - Fixed the node name for i2c4/rtc@51 (was "hym8563@51")
    - Fixed a group control name that didn't match the bindings pattern
    - Re-compared the rest of the DT with the EVK's .dts file to try to
    make sure it complies with the way things should be, hopefully without
    missing anything...

Did you run 'make dtbs_check'? The node name doesn't seem to match
pattern defined by leds-gpio.yaml.

We usually start properties with `compatible`.

Thanks for your patch. Some minor comments below.

I'd have left the FEC node in and described the PHY, but left the FEC disabled.
Only the magnetics are on the expansion board, while the PHY is on the
base board.

I see that Model A and Model B share the same SoC and PCB. Could you
add polyhex,imx8mp-debix as a second compatible? That way, bootloader
may match against that compatible when they support both.
You'll need to adjust the binding accordingly.

Could you append a /* RTL8211E */ comment here? This can be very useful for others
who need to bring up the same chip in the future.

Is the PHY really at address 0 or does it just answer at this address
because it's the broadcast address?

Why do you hog these?

This is unused.

Just to make sure this doesn't fry SD-Cards by mistake: VSELECT is indeed
connected to a 1.8V/3.3V switch powering vqmmc?

I wonder why this is necessary. Do you see a difference
in /sys/kernel/debug/mmcX/ios between having this and leaving
it out?

eMMC

Polyhex also make a SOM with the brand DEBIX.
- https://debix.io/hardware/debix-som-a-io-board.html

But perhaps it will be fine, as that will be
"polyhex,imx8mp-debix-som" (and perhaps they'll do an A/B variant too?)

Fair enough, though there's quite a lot else on the base board which 
we've left off simply because we're not currently using it. I'm inclined 
to treat this the same for now.

I confess I'm unsure here, the number here comes from the downstream 
.dts, which in this instance I've trusted...is there any way I can check?

Ah both for other elements of the board which aren't included in this 
set, as they don't work properly yet. Apologies; I'll remove those.

I don't actually...it's present in the imx8mp-evk.dts which this is 
based on, but in addition to not seeing any difference there the SD card 
still seems fine as far as I can tell (same read / write speed in 
practice) - I'll take it out, thanks

Overall I think it's a good strategy, if we haven't tested a peripheral
we shouldn't include it yet. Missing pieces can be added later. Of
course if there are pieces that are easy to test already, we can include
them.

I generally agree, but I tested the FEC with the magnetics on the I/O board
and the DT description from the older patch set worked correctly.
