965ebf33ea5afb Haavard Skinnemoen 2008-09-17 302 * =======
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 303 *
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 304 * @lock is a softirq-safe spinlock protecting @queue as well as
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 305 * @cur_slot, @mrq and @state. These must always be updated
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 306 * at the same time while holding @lock.
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 307 *
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 308 * @lock also protects mode_reg and need_clock_update since these are
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 309 * used to synchronize mode register updates with the queue
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 310 * processing.
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 311 *
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 312 * The @mrq field of struct atmel_mci_slot is also protected by @lock,
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 313 * and must always be written at the same time as the slot is added to
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 314 * @queue.
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 315 *
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 316 * @pending_events and @completed_events are accessed using atomic bit
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 317 * operations, so they don't need any locking.
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 318 *
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 319 * None of the fields touched by the interrupt handler need any
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 320 * locking. However, ordering is important: Before EVENT_DATA_ERROR or
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 321 * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 322 * interrupts must be disabled and @data_status updated with a
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 323 * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
25985edcedea63 Lucas De Marchi 2011-03-30 324 * CMDRDY interrupt must be disabled and @cmd_status updated with a
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 325 * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 326 * bytes_xfered field of @data must be written. This is ensured by
965ebf33ea5afb Haavard Skinnemoen 2008-09-17 327 * using barriers.

After platform data is gone, we always allocate memory for the slot information. Incapsulate the array of the latter into the host structure, so we allocate memory only once. This makes code simpler.
