i.MX8M SPI DMA

Hello,

 

All eCSPI nodes in imx8mq.dtsi lack "dmas" and "dma-names" properties, see fsl-imx8mq.dtsi\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel. As as result SPI DMA is disabled on i.MX8M. Is there any problem with SPI DMA on this platform ? The eCSPI controller on i.MX8M is the same as on i.MX6UL, but on i.MX6UL SPI DMA is enabled. I'd appreciate a clarification from NXP folks.

 

Thanks a lot.

 

Felix.
