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

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.

Best regards,
