As a precursor to splitting buffer.h, lets make sure all drivers include the relevant headers rather than relying on picking them up from kfifo_buf.h. Signed-off-by: NJonathan Cameron <jic23@kernel.org> Reviewed-by: NLars-Peter Clausen <lars@metafoo.de>

commit 1961bce7 "iio: ina2xx: Remove trace_printk debug statements" removed the code that used the chip->prev_ns field. This patch cleans it up further by removing the unused field and assignments.

Adds a new per-device sysfs attribute "current_timestamp_clock" to allow userspace to select a particular POSIX clock for buffered samples and events timestamping. Following clocks, as listed in clock_gettime(2), are supported: CLOCK_REALTIME, CLOCK_MONOTONIC, CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_COARSE, CLOCK_BOOTTIME and CLOCK_TAI.

The scale would result in uV instead of expected mV. Mostly cosmetic, since the value of 'Power' was computed OK. Signed-off-by: NMarc Titinger <marc.titinger@baylibre.com> Signed-off-by: NJonathan Cameron <jic23@kernel.org>

The user (or an init script) may setup RShunt via sysfs after the driver was initialized, for instance based on the EEPROM contents of a modular probe. The calibration register must be set accordingly. Signed-off-by: NMarc Titinger <marc.titinger@baylibre.com> Signed-off-by: NJonathan Cameron <jic23@kernel.org>

This was extracted from a reposting of the driver after it had been applied to the IIO tree. I have fast tracked it as the driver will be in 4.5 and it would be nice to fix this trivial issue before it is. Signed-off-by: NJonathan Cameron <jic23@kernel.org>

This can lead to repeated or skipped samples depending on the clock beat between the capture thread and the chip sampling clock, but will also spare reading/waiting for the Capture Ready Flag and improve the available i2c bandwidth for reading measurements.

in SOFTWARE buffer mode, a kthread will capture the active scan_elements into a kfifo, then compute the remaining time until the next capture tick and do an active wait (udelay). This will produce a stream of up to fours channels plus a 64bits timestamps (ns). Tested with ina226, on BeagleBoneBlack.
