In imx7s.dtsi the gpio nodes have:

compatible = "fsl,imx7d-gpio", "fsl,imx35-gpio";

If you add fsl,imx7d-gpio entry in the gpio driver, then the match
will be done against "fsl,imx7d-gpio" since it is more specific.

Then in the mx8 dts you can add:

compatible = "fsl,imx8m-gpio", "fsl,imx7d-gpio";

and it will also match the more generic "fsl,imx7d-gpio" compatible.

I did not see the v2. Did you put me on Cc?
