Any idea why do I get this checkpatch.pl warnings: WARNING: Please update ABI in accordance with http://semver.org I did change the SOF_ABI_MINOR from src/include/kernel/abi.h though? |

@dbaluta it's just a nag to make sure ABI increments are not forgotten, although it's not clever enough to know you have updated all the time. Feel free to fix. |

Only add ESAI MCLK ID token for now Signed-off-by: Daniel Baluta <daniel.baluta@nxp.com>

ESAI is one of the DAIs found on i.MX8 platforms. Introduce esai_params used to pass configuration from topology via AP to DSP. Only MCLK and TDM related params for now. Because this is a new struct, increment only ABI MINOR version which makes the SOF FW backward compatible with older kernel versions. Signed-off-by: Daniel Baluta <daniel.baluta@nxp.com>

i.MX8QXP has one ESAI interface. Create a simple topology without a codec for playback of 2 channels, 16bits samples at 48Khz. Host -> Buffer0 -> Volume -> Buffer1 -> ESAI0 This is useful for testing various components like Dummy DMA, EDMA and ESAI drivers. For more information about ESAI you can read i.MX8QXP RM at: https://www.nxp.com/docs/en/reference-manual/IMX8DQXPRM.pdf Signed-off-by: Daniel Baluta <daniel.baluta@nxp.com>

i.MX8QXP contains one ESAI0 interface. This patch series adds helper m4 macros for ESAI and creates a simple playback topology with ESAI0 and nocodec.
With this we can test Dummy DMA, EDMA and ESAI drivers.
Corresponding changes for Linux kernel side will be sent right away.
