The vendor in ODROID-M1 is hardkernel, but it was incorrectly written

You need to start testing your patches. Your last M1 fails as well in
multiple places.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

The DTS change will break the users, so would be nice to mention this in
its commit msg.
I notice there are a couple of other boards that incorrectly use
rockchip as the vendor also:

             - const: rockchip,rk3399-orangepi
             - const: rockchip,rk3568-bpi-r2pro

Perhaps these should also be fixed at the same time?
What is happening with rockchip boards?
Copy-paste stuff ... boards using rockchip,boardname instead of
vendor,boardname for their compatible.

I do remember us noticing this a number of times on some boards
and requesting fixes, but looks like some slipped through.

So I guess Tim is suggesting changing the compatible, but with boards
being merged a while ago, this would break backwards compatibility.
So I guess both the Orange and Banana Pies will need to live with that.
You may get away with it because we generally don't use the names...

Though there are some discussions to start using them to select dtbs by
bootloaders.
Ah, that's good to know (both points) ... so essentially right now would be
a good time to do what Tim suggested, before the names get actual usage.

@Tim: is that something you'd want to do?

Sure, I will prepare patches and send them out soon.
As I stumbled upon this patch just now, how is that coming along? :-)


Thanks for the reminder, I will send them now ;)

Regards
  Tim


Thanks
Heiko
