Enhance SPI using DMA for STM32MP157c-dk2

[swatikumari1-eaton]

I want SPI to use DMA so that I can free the processor for tasks.
Enable feature
Update device tree
When sending/receiving data, the processor should be freed up. With just interrupt-based SPI, it seems like the SPI driver is taking a lot of time to the point where Catalina is not able to meet timing requirements for sampling.

I am enabling CONFIG_SPI_STM32_DMA config then I am getting many linker error

Can somebody suggest!!

I am trying to enable CONFIG_SPI_STM32_DMA macro in my config file but I am getting below error

[erwango]

ok, this likely requires a fix. Could you raise an issue?

Raised..Thanks!!

Ok, Thanks. Note that this isn't a bug as DMA was not supported yet on MP1. We'll work on the support.
