Hi. The following patchset adds support for IDE interface controller found on Cirrus Logic's EP931x CPUs. It is based on an earlier work done by Alessandro Zummo, Lennert Buytenhek, Joao Ramos and Bartlomiej Zolnierkiewicz. I tried to take the best parts of code from previous attempts for inclusion and added dma support. The driver is working correctly in both PIO and DMA mode (with exception that it could give timeouts in DMA mode occasionally - the problem has been solved by me and solution proposed to LAKML; it's not related to this driver, but DMA/interrupt handling of ep93xx IMHO). I'm not sure about correctness of the following in the driver: - module copyrights/authorship - I just added all copyrights of the earlier drivers and MODULE_AUTHOR macro lists their authors, - timeout in IORDY polling (how long to wait for IORDY?), - GPIO/IDE pin muxing - I hope it's done in a way acceptable for ep93xx maintainers (patch 2/3). I would like for the driver to refuse loading when muxing is wrong (first commented out lines of ep93xx_pata_probe, patch 1/3), but some api is needed as raw access to SYSCON register is prohibited in drivers. Patchset is against current mainline kernel.
