New driver for AD7190/AD7192/AD7195 4.8 kHz, Ultralow Noise, 24-Bit
Sigma-Delta ADC with PGA

These devices features a dual use data out ready DOUT/RDY output.
In order to avoid contentions on the SPI bus, it's necessary to use
spi bus locking. The DOUT/RDY output must also be wired to an
interrupt capable GPIO.

In INDIO_RING_TRIGGERED mode, this driver may block its SPI bus segment
for an extended period of time.

Changes since V1:

Add missing documentation.
Remove obsoleted include files.
Fix typos and style issues.
Fix buffer size.
Split ad7192_show() into two functions.
Avoid race condition add mutex.
Abandon IIO_CHAN macro.
Reorder elements in ad7192_platform_data.
Remove driver bus type.

Added suspend/resume functions.
Changed attribute names to match existing where applicable and updated
or documented new ABI as discussed.
Changed integration time ABI from using index (0 to 3) to use actual
gain values (1x,8x, etc.).
Removed various unused variables, declarations, and functions.
Revised code to accommodate different endianess (le16_to_cpu).
Updated error return codes in various functions.
Changed from mdelay to msleep after determining that longer wait would
be acceptable.

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Remove outdated comments.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():
