Top level is saying reset=1, so did you test your bindings?

Umm, I didn't see any errors on dt_binding_check, anyway I'll add
initial minItems:1 and maxItems:3 on top level first.

You need to test also all DTS using these bindings. Yours and others.
If you tested the DTS (with proper binding, not one which is basically
noop):

uniphier-pro4-ace.dtb: sata@65600000: resets: [[27, 12], [27, 28], [37,
3]] is too long

I've tried updating tools and doing dtbs_check, but I couldn't find this
error. It seems that this error can't be detected unless there is the
specified compatible in "select:".

BTW, the patch has other errors - just look at the beginning of the
file. I cannot see it here in the diff, but when you open the file you
should notice it.

Sorry, but I cannot see anything wrong.
I'll check the header or something...

Thank you,
