Hi Dan,
Please have a look at this 3/3 as Vinod mentioned.

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.

Hongbo Zhang (3):
  DMA: Freescale: use spin_lock_bh instead of spin_lock_irqsave
  DMA: Freescale: add suspend resume functions for DMA driver
  DMA: Freescale: change descriptor release process for supporting
