- Remove "mips,mips1004Kc" compatible string from the cpu nodes. This
doesn't exist anywhere.
- Change "memc: syscon@5000" to "memc: memory-controller@5000".
- Change "uartlite: uartlite@c00" to "serial0: serial@c00" and remove the
aliases node.
- Remove "clock-names" from the serial0 node. The property doesn't exist on
the 8250.yaml schema.
- Change "sdhci: sdhci@1e130000" to "mmc: mmc@1e130000".
- Change "xhci: xhci@1e1c0000" to "usb: usb@1e1c0000".
- Add "mediatek,mtk-xhci" as the second compatible string on the usb node.
- Change "switch0: switch0@0" to "switch0: switch@0"
- Change "off" to "disabled" for disabled nodes.
Remaining warnings are caused by the lack of json-schema documentation.

Instead of removing this, since compatible is correct here, I think a
cpus yaml file needs to be added to properly define mips CPU's but
compatible strings using all around the sources are a bit messy. Take
a look of how is this done for arm [0]

I think syscon nodes need to use 'syscon' in the node name, but I am
not 100% sure.

I did investigate the arm bindings beforehand. I've seen that some of
the strings are also checked by code. I don't see the mips strings used
anywhere but DTs so I had decided to remove it here. I guess we can make
a basic binding to list the mips processor cores.
What do you think Thomas?

I've tested this patch series on my GB-PC2, it currently works fine.
Also, DT binding for MT7621 memory controller uses memory-controller on
the example so I guess it's fine?

At the very least I do think a compatible string should exist for cpu
nodes :). And because of the mess with MIPS cpu nodes in dts files all
around I think we should only add this 'compatible' as a requirement
and mark 'reg' and 'device_type' as optionals.

I know that works fine but when the node is a syscon it is good to
have that syscon in the node name (I don't know if having it is a rule
or something, I guess no). In any case I agree that binding and dts
should match.

I have just sent a patch to start from containing all compatible
strings I have found in the 'arch/mips/boot/dts' folder:

Awesome, I'll keep the string on v2.
