This patch serial is to update the supported format for fsl_asrc
and fix some format issue.
Shengjiu Wang (4):
ASoC: fsl_asrc: Use in(out)put_format instead of in(out)put_word_width
ASoC: fsl_asrc: update supported sample format
ASoC: pcm_dmaengine: Extract
snd_pcm_format_t is more formal than enum asrc_word_width, which has
two property, width and physical width, which is more accurate than
enum asrc_word_width. So it is better to use in(out)put_format
instead of in(out)put_word_width.

Fixed point controls are used by the user to configure
the audio sample rate to driver.
Add V4L2_CID_ASRC_SOURCE_RATE and V4L2_CID_ASRC_DEST_RATE
new IDs for ASRC rate control.

changes in v2:
- decouple the implementation in v4l2 and ALSA
- implement the memory to memory driver as a platfrom driver
and move it to driver/media
- move fsl_asrc_common.h to include/sound folder

ASoC: fsl_asrc: define functions for memory to memory usage
ASoC: fsl_
output length according to input length
m2m_get_maxburst: burst size for dma
m2m_pair_suspend: suspend function of pair, optional.
m2m_pair_resume: resume function of pair
get_output_fifo_size: get remaining data size in FIFO
