The last patch (4/4) adds the support. 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). I had to chop through the driver to add support for sama7g5, so, let me know what you think, if something would need changing. Thanks, Eugen Eugen Hristev (4): dt-bindings: iio: adc: at91-sama5d2: add compatible for sama7g5-adc iio: adc: at91-sama5d2: initialize hardware after clock is started iio: adc: at91-sama5d2: remove unused definition iio: adc: at91-sama5d2: add support for sama7g5 device .../bindings/iio/adc/atmel,sama5d2-adc.yaml | 1 + drivers/iio/adc/at91-sama5d2_adc.c | 293 ++++++++++++++---- 2 files changed, 237 insertions(+), 57 deletions(-)
