Per the current implementation yes, worst case if one or more of them isn't the more specific compatible can be used to alter the behavior of that platform. > Why not using dedicated compatible of one soc, e.g. the > oldest here? We already did like that for BWMON, DMA and few others. > Because if we say compatible = "qcom,sc8180x-osm-l3", "qcom,sdm845-osm-l3" and there is a quirk needed for "qcom,sdm845-osm-l3" we're forced to add a "special case" every other *-osm-l3 in the driver. This way we can have a generic implementation for the qcom,osm-l3 and if we realize that we need to quirk something for the oldest platform, we can do so without affecting the others.
