[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Allow parsing GPIO controller children nodes with GPIO hogs to fix the
following warning:

  uniphier-ld11-ref.dtb: gpio@55000000: 'xirq0-hog' does not match any of the regexes: 'pinctrl-[0-9]+'
      From schema: Documentation/devicetree/bindings/gpio/socionext,uniphier-gpio.yaml
