IIO: ADC: New driver for the AD7298 8-channel SPI ADC This patch adds support for the AD7298: 8-Channel, 1MSPS, 12-Bit SAR ADC with Temperature Sensor via SPI bus. This patch replaces the existing ad7298.c driver completely. It was necessary since, the old driver did not comply with the IIO ABI for such devices. Changes since V1: IIO: ADC: New driver for the AD7298 8-channel SPI ADC Add documentation for new sysfs file tempX_input. Simplify bit defines. Remove outdated comments. Fix indention style. ad7298_show_temp(): Add locking. Simplify temperature calculation. Change temperature result from degrees into milli degrees Celsius. Rename file according to new sysfs ABI documentation Add timestamp attributes. Revise timestamp handling accordingly. Preset timestamp generation.

staging:iio: Move the ad7298 driver out of staging The driver does not expose any custom API to userspace and none of the standard static code checker tools report any issues, so move it out of staging.
