[PATCH v4 0/2] Add Freescale ASRC driver

[Nicolin Chen]

This series of patches add Freescale ASRC module driver support along
with the extra request in imx-sdma structure required by SDMA Device
to Device script.

The previous version has been in the maillist for nearly six months
without any comment and reply. So I decide to drop the SDMA part's
change since this series focus on ASRC support (Later, we can send
SDMA part separately.) so that ASRC driver may get upstream first.

Changelog

 * PATCH-2: Added '\n' to dev_dbg() inside fsl_asrc_isr().
 * PATCH-2: Added indentations to DT binding document.
 * PATCH-2: Redefined fsl_asrc_set_watermarks() as void type.
 * PATCH-2: Put fsl_asrc_isr() and fsl_asrc_ids before probe()

 * PATCH-1: Added an Acked-by from Shawn Guo
 * PATCH-2: Dropped THIS_MODULE as Tobias suggests
