e931609425 dt-bindings: gpio: vf610: Add i.MX94 support 
Add compatible string "fsl,imx94-gpio" for the i.MX94 chip, which is
backward compatible with i.MX8ULP. Set it to fall back to
"fsl,imx8ulp-gpio".

1619a09444 dt-bindings: gpio: vf610: correct i.MX8ULP and i.MX93 
i.MX8ULP and i.MX93 actually has two interrupts for each gpio
controller, one for Trustzone non-secure world, one for secure world.

And they has one register based, not two as i.MX7ULP or VF610.

Although the Linux Kernel driver gpio-vf610.c could work with
fsl,imx7ulp-gpio compatible, it is based on some tricks did in
device tree with some offset added to base address.

So actually i.MX8ULP/i.MX93 is not compatible with i.MX7ULP.

Last, i.MX93 is directly derived from i.MX8ULP, so make i.MX93 GPIO
compatible with i.MX8ULP

690acef3c4 dt-bindings: gpio: vf610: update gpio-ranges 
i.MX93 supports four gpio-ranges at max. To fix below issue:
"gpio@43820080: gpio-ranges: [[30, 0, 84, 8], [30, 8, 66, 18],
 [30, 26, 34, 2], [30, 28, 0, 4]] is too long"

 Update the gpio-ranges property
