AM5718: SPI configuration

Hi Khushboo,

for that you would want to have a look at the "IIO" framework in the Kernel. There is already a large library of supported ADC/DACs (via SPI, I2C, etc.). I would see that you can use one of those devices (preferably one from TI:) that already has a driver in your current Kernel (or in the upstream Kernel, so you can backport) to avoid development effort (although ADC/DAC drivers are not too hard to do from scratch, based on leveraging code from existing drivers).

https://www.kernel.org/doc/html/v4.19/driver-api/iio/index.html

https://git.ti.com/cgit/processor-sdk/processor-sdk-linux/tree/drivers/iio?h=processor-sdk-linux-4.19.y

There's a wealth of information out there on that topic if you search for it but hopefully this gives you something to start from.

Also please move to Processor SDK v6.x+ to benefit from a larger selection of supported IIO devices (and other improvements).

Regards, Andreas
