Proposal for GSoC 2019 IIO Driver: AD7292

Main goal: have the AD7292 driver in the Linux kernel tree.

Secondary goal: develop a series of tutorial posts for newcomers.

The following summarizes the deliverables I want to provide.

• AD7292 driver

Develop the AD7292 driver incrementally adding small pieces of code every week and gathering feedback from the community during this process. This deliverable will be the sum of several minor contributions along the entire GSoC period.

• Post about AD7292 structure overview

A first blog post describing the main blocks of code that should compose de AD7292 driver. This post will aim to elucidate for the basic structure of an IIO driver comprehensively for newcomers.

• Post about AD7292 SPI

Approach how an IIO driver communicates through SPI. What kind of API does IIO have to help to establish communication with an SPI device?

• Post about AD7292 operation details

Describe the driver’s probe, read_raw, and write_raw functions. I may want to talk about the IIO channels, the ABI, the support for devicetree and other stuff so this can give origin to a tutorial composed by a series of posts.

• Post about Final results on the AD7292

Final post about the operation of the driver as a whole.
