[PATCH 4/4] ASoC: fsl_asrc: swap input and output clocks in capture mode

streams. As some of the clocks have different ID's depending on whether they are used as input or output, this requires adding a new function to find the output clock ID corresponding to a given input clock. Signed-off-by: Arnaud Ferraris --- sound/soc/fsl/fsl_asrc.c | 50

[PATCH 3/4] ASoC: fsl_asrc: always use ratio for conversion

Even when not in "Ideal Ratio" mode, ASRC can use an internally measured ratio, which greatly improves the conversion quality. This patch ensures we always use at least the internal ratio. Signed-off-by: Arnaud Ferraris --- sound/soc/fsl/fsl_asrc.c | 5 ++--- 1 file changed, 2 insert

[PATCH 1/4] dt-bindings: sound: fsl, asrc: add properties to select in/out clocks

The ASRC peripheral accepts a wide range of input and output clocks, but no mechanism exists at the moment to define those as they are currently hardcoded in the driver. This commit adds new properties allowing selection of arbitrary input and output clocks. Signed-off-by: Arnaud Ferraris
