The i.MX ASRC and EASRC hardware each support multiple independent
conversion pairs or contexts, but both drivers previously registered
only a single DAI with generic stream names. This prevented individual
pairs or contexts from being routed to separate audio paths at the same
time.
This series updates the DT bindings and drivers to expose one DAI per
conversion unit:
- fsl,imx-asrc: add a ports container (port@0/1/2 for pairs A/B/C)
alongside the deprecated single port property
- fsl,easrc: add a ports container (port@0/1/2/3 for contexts A/B/C/D)
- fsl_asrc: register three DAIs (paira/pairb/pairc); pair A keeps the
original stream names for backward compatibility
- fsl_easrc: register four DAIs (ctxa/ctxb/ctxc/ctxd); context A keeps
the original stream names for backward compatibility
Shengjiu Wang (4):
dt-bindings: sound: fsl,imx-asrc: update port binding to support
multiple pairs
dt-bindings: sound: fsl,easrc: add ports binding for multiple contexts
ASoC: fsl_asrc: expose individual DAIs per conversion pair
ASoC: fsl_easrc: expose individual DAIs per conversion context
