I take back Ack for socionext,uniphier-gpio.yaml



Now "make dt_binding_check" produces a new warning.

gpio@...00000: 'interrupt-parent' does not match any of the regexes:
'pinctrl-[0-9]+'


This binding uses 'interrupt-parent'
without 'interrupts'.

Instead, the mapping of the interrupt numbers
is specified by the vendor-specific property
socionext,interrupt-ranges



I cannot add   "interrupt-parent: true" because
dt-schema/meta-schemas/interrupts.yaml
has "interrupt-parent: false".


Is there any solution?
