Then what's your problem with these patches again ? I am just asking the driver to match the generic binding instead of the SoC specific, because we are also using it on other SoC, as explain in the patch comment. Does not seems that "pointless" to me. Right now the driver match only on: vendor,soc-one in dts, we have compatible = "vendor,family", "vendor,soc-one" but it is compatible with soc-two as well. to match we would have to put "vendor,soc-one" as well which is a mess By expressing correctly what the driver is compatible with, "vendor,family" we can dts that makes sense for soc-two as well compatible = "vendor,family", "vendor,soc-two" Same goes for the other patches > > Rob -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
