-Amlogic Meson Firmware registers Interface
-------------------------------------------
-
-The Meson SoCs have a register bank with status and data shared with the
-secure firmware.
-
-Required properties:
- - compatible: For Meson GX SoCs, must be "amlogic,meson-gx-ao-secure", "syscon"

I have a hard time find how to define "syscon" here, if I put syscon in the compatible
it gets matched on other bindings and I get lot of warnings.

How should I model it ?

You have to add a custom 'select' key that doesn't include 'syscon'.
There should be a few examples in the tree.
