[dts] Does "fsl, sai-synchronous-rx" set SAI to I2S Slave?

[Takashi_Kashiwagi]

Hi Community.

We want to run SAI as Slave of I2S / TDM as follows.

According to fsl-sai.txt\sound\bindings\devicetree\Documentation - linux-imx - i.MX Linux kernel ,

there is an option called “fsl, sai-synchronous-rx”.

Can this option be used when TX_SYNC / TX_BCLK / MCLK is not connected as shown above?

Do I need to connect MCLK?

Best Regards,

T.Kashiwagi
