Hi Vinod Koul, Please have a look at the v5 patch set. v4 -> v5 changes: - since previous 5 of 8 patches have been merged by Vinod, this iteration oly inludes the last 3 patches of v4. - patches order is changed for being reviewed and merged easier. - remove the .prepare functions, and use the suspend_late and resume_early in the suspend-and-resume patch. v3 -> v4 changes: - Fixed a typo in [2/8] commit message. - There was a potential double call of list_del() when apply [4/8] only, although this defect is removed again in later [6/8]. This version eliminates this problem by updating [4/8] and [6/8] slightly. - Updated [8/8] to use register access method introduced by [2/8] v2 -> v3 change: Only add "chan->pm_state = RUNNING" for patch[8/8]. v1 -> v2 change: The only one change is introducing a new patch[1/7] to remove the unnecessary macro FSL_DMA_LD_DEBUG, thus the total patches number is 8 now (was 7) v1 notes: Note that patch 2~6 had beed sent out for upstream before, but were together with other storage patches at that time, that was not easy for being reviewed and merged, so I send them separately this time.
