iio: adc: ad7616: Add support for AD7616 ADC The AD7616 is a 12-bit ADC with 16 channels. The AD7616 can be configured to work in hardware mode by controlling it via gpio pins and read data via spi. No support for software mode yet, but it is a work in progress. This device requires a reset in order to update oversampling, so chip info has got a new attribute to mark this. The current assumption that this driver makes for AD7616, is that it's working in Hardware Mode with Serial, Burst and Sequencer modes activated. To activate them, following pins must be pulled high: -SER/PAR -SEQEN And following must be pulled low: -WR/BURST -DB4/SEQEN Datasheets: Link: https://www.analog.com/media/en/technical-documentation/data-sheets/ad7616.pdf Signed-off-by: Beniamin Bia <beniamin.bia@analog.com> Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
