AM6421: Enabling DMA for internal ADC via Device Tree

Part Number: AM6421

Tool/software:

Hello,

I am working on AM6421 ,

I want to achieve deterministic ADC sampling with consistent timing for all 8 internal ADC channels.

I plan to use a hardware timer trigger along with DMA to store internal ADC data in a buffer.

So what changes are required in the device tree and kernel to enable DMA support for the ADC on the AM4621? Are there existing examples or documentation that outline the necessary steps? and is there anything else I need to change in code ?
