This patch enables Tx-related SIER_FLAGS only when direction is PLAYBACK
and does same thing for CAPTURE. Also, after TRIGGER_STOP/PAUSE, it will

Naming issue here again.
At least from my point of view, if you actually merged imx-sgtl5000 with
vf610-sgtl5000 and made it also compatible to othe

However, your driver doesn't take care of them.
The SAI's synchronous mode looks like more flexible

so that it can handle multiple cases when TX/RX clocks

The normal mode of SSI allows it to send/receive data to/from the first

Patch-1 adds device to device support in SDMA driver along with a secondary
request in struct imx_dma_data which's requred in the Patch-2 ASRC driver.

This patch adds DEV_TO_DEV support for i.MX SDMA driver to support data

Is that possible for you to drop this one? If not, I'll send another patch

For trigger start, we don't need to check if it's the first time to
enable TE/RE or second time. It doesn't hurt to enable them any way,
which in the meantime can reduce race condition for TE/RE enabling.
For trigger stop, we will definitely clear FRDE of cu

TE/RE bit of T/RCSR will remain set untill the current frame is physically
finished. The FIFO reset operation should wait this bit's totally cleared
rather than ignoring its status which might cause TE/RE disabling failed.
This patch adds delay and timeout to wait fo

The previous enable flow:
1, Enable TE&RE (SAI starts to consume tx FIFO and feed rx FIFO)
2, Mask IRQ of Tx/Rx to enable its interrupt.
3, Enable DMA request of Tx/Rx.
As this flow would enable DMA request later than TERE, the Tx FIFO
would be easily emptied into unde
