2013-03-20staging/iio: iio_hwmon: Use device tree node name for hwmon name attributeGuenter Roeck
So far, all instances of iio_hwmon set their hwmon name attribute to "iio_hwmon", which is not very descriptive. Set it to the device tree node name if available, and only revert to iio_hwmon otherwise. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-03-17iio: adc: Add dt support for turning on the phy in exynos-adcDoug Anderson
Without this change the exynos adc controller needed to have its phy enabled in some out-of-driver C code. Add support for specifying the phy enable register by listing it in the reg list.

2013-03-17iio:adc:ad7923: Add support for the ad7904/ad7914/ad7924Lars-Peter Clausen
The ad7924 is software compatible with the ad7923. The ad7904 and ad7914 are the 8 and 10 bit version of the ad7924. While we are at it also drop the "with temperature sensor" from the Kconfig entry, since the chips do not have a temperature sensor.

2013-03-17iio:ad7923: Implement scale reportingLars-Peter Clausen
The driver already claims to support scale reporting in its channel spec, but doesn't actually implement this yet. This patch uses the regulator API to get the reference voltage and calculates the scale based on that. The patch also moves the global configuration bits into a field in the ad7923_state struct, since depending on the RANGE bit, the range goes either from 0 to VREF or from 0 to 2 * VREF. So we need to know the setting of the RANGE bit when calculating the scale.

As the exynos_adc driver only supports device tree registration. Making driver depend on CONFIG_OF solves possible errors during probe.

2013-03-17iio: events: Make iio_push_event() IRQ context saveLars-Peter Clausen
Currently it is not save to call iio_push_event() from hard IRQ context since the IIO event code uses spin_lock()/spin_unlock() and it is not save to mix calls to spin_lock()/spin_unlock() from different contexts on the same lock. E.g. if the lock is being held in iio_event_chrdev_read() and an interrupts kicks in and the interrupt handler calls iio_push_event() we end uo with a deadlock. This patch updates iio_push_event() to use spin_lock_irqsave()/ spin_unlock_irqstrestore(), since it can be called from both IRQ and non-IRQ context. All other other users of the lock, which are always run in non-IRQ context, are updated to spin_lock_irq()/spin_unlock_irq().
