Ok. Do you think that we can go forward with this patch series if I drop the last patch (spi/ep93xx: add DMA support)? This way we will have dmaengine implementation in place, whatever SPI driver we choose to use with ep93xx. We can then try to use amba-pl022 driver with ep93xx and see if it works or not, and how much work is needed. I would like some comments from Hartley and Ryan also. > Is there some inexepensive hardware with EP93xx I can get to fix this > myself? Check for example Technologic Systems (embeddedarm.com), I have their TS-7260 board which has ep9302. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
