Hi, This series adds support for sama7g5. The sama7g5 is slightly different from sama5d2, but has the same basic operations. The register map is a bit different, so, I added some primitives to differentiate between the two classes of hardware blocks (sama5d2-sam9x60 and sama7g5). Sama7g5 has 16 channels ADC, no resistive touch, and extra features (FIFOs, better oversampling , not implemented yet). It is a rework of the series initially sent here: https://marc.info/?l=linux-iio&m=161461656807826&w=2 Changes in v3: updates for the channel indexes ABI minor nitpicks fixes fixed krobot report Changes in v2: I reworked this according to review by Jonathan, meaning that first I created a no-op patch that will convert the driver to a more platform specific data dedicated type of driver. This adds various structures that hold things like register layout and channel information. After this I created few patches that implement the main differences between sama7g5 and older products: the end-of-conversion new register. I added helper functions to make code more easy to read and more simple. One the last patches adds the layout and channels for sama7g5. At this moment in linux-next, the DT for sama7g5 and sama7g5ek is present, and the last patches add and enable this node in DT for this board.
