The current ASRC driver hardcodes the input and output clocks used for
sample rate conversions. In order to allow greater flexibility and to
cover more use cases, it would be preferable to select the clocks using
device-tree properties.

This series also fix register configuration and clock assignment so
conversion can be conducted effectively in both directions with a good
quality.

Arnaud Ferraris (4):
dt-bindings: sound: fsl,asrc: add properties to select in/out clocks
ASoC: fsl_asrc: allow using arbitrary input and output clocks
ASoC: fsl_asrc: always use ratio for conversion
ASoC: fsl_asrc: swap input and output clocks in capture mode
