Subject[PATCH 0/3] Add dual-fifo mode support of i.MX ssi
Date
Changelog
v1:
* SSI can reduce hardware overrun/underrun possibility when using dual
* fifo mode. To support this mode, we need to first update sdma sciprt
* list, and then enable dual fifo BIT in SSI driver, and last update DT
* bindings of i.MX series.
*
* ! This series of patches has a direct dependency between them. When
* ! applying them, we need to apply in one single branch. Otherwise,
* ! it would break currect branches.

dma: imx-sdma: Add ssi dual fifo script support
ASoC: fsl_ssi: Add dual fifo mode support
ARM: dts: imx: use dual-fifo sdma script for ssi
