I meant that when ST-Ericsson imploded, STMicroelectronics inherited the SoC family but never did any follow-up chips. We only really ever supported the original U8500 but not the later models (which have partial support), and that is very unlikely to change, so all the devices that can run this driver are already known. This is only relevant because the dynamic allocation size depends on the chip model. > Mixup with SuperH-based ST40? No, but I wouldn't be surprised to find an ST40 inside the D40 engine ;-) Arnd -- To unsubscribe from this list: send the line "unsubscribe dmaengine" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
