is it possible to use the Linux SDMA driver for I2C communication on a i.MX8MQ (EVK)?
I see DMA releated code in drivers/i2c/busses/i2c-imx.c. But when booting Linux 4.14.78 I get
i2c i2c-0: IMX I2C adapter registered
i2c i2c-0: can't use DMA, using PIO instead.
I supposed I need to configure the device tree accordingly. But Documentation/devicetree/bindings/dma/fsl-imx-sdma.txt does not mention I2C as possible peripheral type.
Thanks in advance!
