My understanding is that it would be better to add a mtk specific
compatible instead of adding this "generic-reset", especially since we
can't guarantee this binding will be considered generic in the future.
I think there is nothing wrong with specifying
compatible = "mtk,your-compatible", "ti,syscon-reset";
in your device tree if your hardware is indeed compatible with the
specified "ti,syscon-reset" binding, but I may be wrong: Therefore,
please add devicetree@vger.kernel.org to Cc: for binding changes.
regards
Philipp
