We did that because the same core is used in many different platforms (OMAP, discrete chips, ST-Ericsson, DaVinci, PCI cards, etc) so we needed to "abstract" platform-specific details such as clock handling and power management. There's still work to be done, for sure, e.g. the DMA part is still quite screwed up, but the drivers are correctly named which means they should be matching and probing. Now, musb-hdrc isn't probing, as you say, and I'd like to know why. I'll try to spend some time in it when I get back to the office. -- balbi -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
