This leads to warnings upon dtbs_check, e.g.
arch/arm64/boot/dts/freescale/imx93-tqma9352-mba93xxla.dtb: gpio@43810000: 
'ngpios' does not match any of the regexes: '^.+-hog(-[0-9]+)?$', 'pinctrl-
[0-9]+'
  from schema $id: http://devicetree.org/schemas/gpio/gpio-vf610.yaml#

Please address this as well.

Best regards,
Alexander
