ECSPI to SPI Controller Interface dts in iMX8MM

[sreedhar_appala]

Hi,

I am working with IMX8M Mini EVK and yocto project build details:

Build Configuration:
BB_VERSION = "1.38.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "ubuntu-16.04"
TARGET_SYS = "aarch64-poky-linux"
MACHINE = "imx8mmevk"
DISTRO = "fsl-imx-xwayland"
DISTRO_VERSION = "4.14-sumo"
TUNE_FEATURES = "aarch64"
TARGET_FPU = ""

We are interfacing Cx2070x evaluation board with iMX8MM EVK through ECSPI.
ECSPI2 of iMX8MM as Master and SPI controller of Cx2070x evaluation board as slave.

Do you have any suggestions/example code for dts changes for this kind of hardware interface.

Thank you,
Sreedhar
