Hello Andy,

    I have confirmed about issues with my colleague, see following, please!

------------------

>>1. page 173,  SAI3 only RX FIFO on SDMA event 39 and 40

Correction : 40 is for SAI3 TX FIFO

2. page 1272, SDMA_event only  sai2.ipd_req_sai_tx,  sai2.ipd_req_sai_rx,  sai1.ipd_req_sai_tx 

    Have any SAI3 setting on sdma_event?

No errors here! it is not used to select MUX for SAI3's DMA events in I.MX6UL.

Actually, All SAIs have no need to configure GPR to select MUX for their DMA events.

-------------------

Best Regards,

Weidong
