Before sending v2 could you run "make dt_binding_check" for the DT schema
modified in this patch? Like this:

make -j8 ARCH=mips CROSS_COMPILE=mipsel-baikal-linux- dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/gpio/snps,dw-apb-gpio.yaml

Yep, you've removed the "compatible" property but forgot to do the same from the
"required:" property of the sub-nodes schema. That's why the suggested
make-command above would have failed during the DT schema examples validation if
you ran it. Please, fix it and resend the series.

Yeah. Here I've forgotten to add the "reg" property constraints. Since certainly
the controller won't have more than four sub-nodes by design, could you add one
in an additional patch of the series since you'll need to resend the patchset anyway?
Like this:
       reg:
-        maxItems: 1
+        minimum: 0
+        maximum: 3
