Also: you can include rate here if you need a convenient place to store it (which sadly means that this structure can't be const). ...but I do like Tomasz's idea of actually calculating it. You can't know it at compile time since the parent rate comes from the device tree. compatible = "samsung,clock-xxti"; clock-frequency = <24000000>; > + unsigned int pdiv; > + unsigned int mdiv; > + unsigned int sdiv; > + unsigned int kdiv; I think kdiv is signed. -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
