[PATCH v5 00/21] ASoC: fsl_micfil: Driver updates

[Sascha Hauer]

This series has a bunch of cleanups for the FSL MICFIL driver. There is
not much chance for regressions in this series as the driver currently
can't work at all. The MICFIL needs multififo support in the i.MX SDMA
engine which is added with this series, see 11/20.

The multififo support is selected in the dma phandle arguments in the
device tree, the transfer type must be '25' aka IMX_DMATYPE_MULTI_SAI.
This is set already to 25 in the upstream i.MX8M[NM] dtsi files, but the
SDMA driver silently ignores unsupported values instead of throwing an
error. This is fixed in this series and multififo support is added.

The dmaengine patches have acks from Vinod, so the series is free to
go through the ASoC tree.

Changes since v4:
- collect more acks
- whitespace cleanup in 16/21

Changes since v3:
- Add commit log to "ASoC: fsl_micfil: drop unused variables"
- Fix include name in "ASoC: fsl_micfil: add multi fifo support"
- Drop unnecessary temporary adding of struct fsl_micfil::osr
- Leave default quality setting at 'medium'
- Drop debugging message printed at error level
- collect acks from Shengjiu Wang and Vinod Koul

Changes since v2:
- Add forgotten commit log to dmaengine patches
- Add patch to move include/linux/platform_data/dma-imx.h to include/linux/dma/imx-dma.h
- Use prefix dmaengine: for dma patches

Changes since v1:
- Drop unused variable sw_done_sel
- Evaluate sdmac->direction directly instead of storing value in n_fifos
- add missing include linux/bitfield.h
