According to NXP HRM for i.MX93, the following GPIO pins are available:
- GPIO1: 16 pins (0..15)
- GPIO2: 30 pins (0..29)
- GPIO3: 32 pins (0..31)
- GPIO4: 30 pins (0..29)

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,
