Add support for imx8qm. Shengjiu Wang (2): ASoC: fsl_esai: introduce SoC specific data ASoC: fsl_esai: Add new compatible string for imx8qm Changes in v2 - drop the 0002 patch in v1, the dma relate limitation should be done in dma driver, or define a new DMA API for it. .../devicetree/bindings/sound/fsl,esai.txt | 1 + sound/soc/fsl/fsl_esai.c | 46 +++++++++++++++---- 2 files changed, 38 insertions(+), 9 deletions(-) -- 2.21.0
