[PATCH 00/19] 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 10/19.

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.

I think the series should go via the ASoC tree, so I'll need an ack from
the DMA guys for 9/19 and 10/10.
