Hi marcingrzelak

please look at linux/Documentation/devicetree/bindings/spi/fsl-imx-cspi.txt  

Since sdma/ecspi modules are the same as in i.MX6DQ/SDL one can look at example in

linux/arch/arm/boot/dts/imx6qdl.dtsi
http://git.freescale.com/git/cgit.cgi/imx/linux-imx.git/tree/arch/arm/boot/dts/imx6qdl.dtsi?h=imx_4....

Best regards
igor
