Subject: [PATCH v3 0/3] gpio: support i.MX93 truly available GPIO pins

All four GPIO ports of i.MX93 SoC show 32 pins available, but
not every port has 32 pins.
Add support on the GPIO driver to 'ngpios' property and set
the truly available pins on the SoC device tree.

v3
* Move DT bindings to a patch of its own
* Improve reasoning for adding support in driver

v2
* Add 'ngpios' property to DT binding for proper validation

Hector Palacios (3):
      gpio: vf610: add support to DT 'ngpios' property
      dt-bindings: gpio: vf610: add optional 'ngpios'
      arm64: dts: imx93: specify available 'ngpios' per GPIO port
