This patch set does two things about the MXS-DMA:
[1] patch 1 ~ patch 5: move the mxs dma header to a more common place.
	Beside the mx23/mx28, the APBH-DMA is also used by MX50 and MX6Q.
	So move the mxs dma header file to a more common place, and rename
	it to mxs-dma.h

For the sake of bitsec, these 5 patches need to be one.

[2] patch 6 ~ patch 10: rewrite the last parameter of mxs_dma_prep_slave_sg().

For the sake of bitsec, at least patches #7 and #8 need to be one patch.
That said, if I apply the series and then check out the commit at patch
#7, you need to all mxs-dma client drivers, mxs-mmc, gpmi do not break.

	In the new GPMI version, some hardware behavior changes.
	The WAIT4END bit should be set in the middle one of the ECC READ page DMA chain.
	The DMA chain should be set like this:

          +-----+               +-----+                      +-----+
          | cmd | ------------> | cmd | ------------------>  | cmd |
          +-----+               +-----+                      +-----+
                                   ^                            ^
                                   |                            |
                                   |                            |
                              set WAIT4END here too        set WAIT4END here

         Please read the comment in patch "MXS-DMA : add more flags for MXS-DMA".

Huang Shijie (10):
  MXS-DMA : move the mxs-dma.h to a more common place
  MXS-DMA : change the header
  MXS-MMC : change the DMA header file
  MTD/GPMI : change the DMA header file
  ASoc : change the DMA header file
  MXS-DMA : add more flags for MXS-DMA
  MXS-DMA : change the last parameter of mxs_dma_prep_slave_sg()
  MXS-MMC : use the new DMA flags
  MTD/GPMI : add a new field `gpmi_version`
  MTD/GPMI : change the code for new DMA interface

Please try to make these subject prefix consistent with the existing
ones in the tree.  You can get them from 'git log' output.  For example
"mxs-dma: ..." is better than "MXS-DMA : ...".
