Here's the pertinant question: "is it platform data?" Looking at the file, it appears to be internal data structures and register definitions for the driver itself. Therefore, it isn't platform data, and it shouldn't be living separately from the driver. If the driver itself only makes use of the data structures, the data structures should be defined either within the driver, or a header file co-located next to the driver itself. The same goes for register definitions too. The only structure that I can find which isn't internal to the driver is struct edma_soc_info, struct edma_rsv_info, and the enum dma_event_q. Those can go to include/linux/platform_data, but the rest should not. -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
