Hello there,
I am absolutely new to device tree and device tree overlay. I am using Raspberry Pi 4B as my microcontroller. And I have successfully re-compiled the kernel with the driver for AD5360/70 and am able to successfully load the driver using "modprobe ad5360".
I definitely think there are some major issues in my DTS file that i created using https://wiki.analog.com/resources/tools-software/linux-drivers/iio-dac/ad5360 information. Please can you help me debug my DTS file.
