[alsa-devel] [PATCH 7/8] ASoC: SOF: imx: Describe SAI parameters to be sent to DSP

[Pierre-Louis Bossart]

From: Guido Roncarolo <guido.roncarolo at nxp.com>

Introduce sof_ipc_dai_sai_params to keep information that
we get from topology and we send to DSP FW.
For the moment it is identical to ESAI one but it will
evolve shortly independently
