I initially used the license commonly used by Amlogic (reference: meson-s4-gpio.h):
```
/* SPDX-License-Identifier: (GPL-2.0+ OR MIT) */
```

But when I checked the patch, some warnings appeared:
```
WARNING: DT binding headers should be licensed (GPL-2.0-only OR .*)
#37: FILE: include/dt-bindings/gpio/amlogic-c3-gpio.h:1:
+/* SPDX-License-Identifier: (GPL-2.0+ OR MIT) */
```
So I followed the prompts and changed the license.

Can I ignore this warning and use the (GPL-2.0+ OR MIT) license?
