The "edge detection interrupt" subdevice supports the
`INSN_CONFIG_CHANGE_NOTIFY` comedi instruction which is only supported
by one other driver.  It is limited to the first 32 channels, but boards
supported by this driver support edge detection on all digital I/O,
digital input and digital output channels.  The
`INSN_CONFIG_DIGITAL_TRIG` comedi instruction is more flexible as it
supports more than 32 channels (with multiple instructions).  It can
also support level detection, but the hardware does not support that.

Add partial support for the `INSN_CONFIG_DIGITAL_TRIG` instruction, but
only for edge detection.

Since `INSN_CONFIG_CHANGE_NOTIFY` can only deal with 32 channels, make
it disable edge detection for any remaining channels.

Refactor the code that updates the rising and falling edge detection
registers into new function `ni_65xx_update_edge_detection()`.  This
updates the rising and falling edge detection registers for up to 32
channels starting at an arbitrary channel.  Call it from the code that
handles the `INSN_CONFIG_CHANGE_NOTIFY` instruction, which is limited to
the first 32 channels.

(For the purposes of edge detection, the channels are in the natural
port order of the board, 8 channels per port.  In practice, this is all
the digital I/O channels (if any), followed by all the digital input
channels (if any), followed by all the digital output channels (if any).

Merge tag 'iio-for-3.17d' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Fourth round of IIO new drivers, functionality and cleanups for the 3.17 cycle

New functionality
* A new modifier to indicate that a rotation is relative to either
  true or magnetic north.  This is to be used by some magnetometers
  that provide data in this way.
* hid magnetometer now supports output rotations from various variants on
  North
* HMC5843 driver converted to regmap and reworked to allow easy support
  of other similar devices.  Support for HMC5983 added via both i2c and SPI.
* Rework of Exynos driver to simplify extension to support more devices.
* Addition of support for the Exynos3250 ADC (which requires an additional
  clock)  Support for quite a few more devices on its way.

Cleanups
* ad7997 - a number of cleanups and tweaks to how the events are controlled
  to make it more intuitive.
* kxcjk - cleanups and minor fixes for this new driver.

The driver hasn't been fully cleaned up and it doesn't look like anyone
is working on it anymore (including the original author). So remove the
driver and all references to it. If someone wants to finish cleaning
the driver up and moving it out of staging, this commit can be reverted.

The state of the driver hasn't improved much since it was added to

remove it. This commit can be reverted if someone wants to clean the

The issue was reported by static analysis.
The value holding flags was &-ed with 0x02, being compared to 0x01
(TRUE) after that. Such comparsion is always false.

Resolution: drop the comparsion to TRUE in the condition.

&-ing with 0x02 is right, according to result variable name
(reporting_mode) and description in drivers/staging/bcm/target_params.h
("bit 1 = 1: CINR reporting in Idlemode Msg").

This patch control special clock for ADC in Exynos series's FSYS block.
If special clock of ADC is registerd on clock list of common clk framework,
Exynos ADC drvier have to control this clock.

Exynos3250/Exynos4/Exynos5 has 'adc' clock as following:
- 'adc' clock: bus clock for ADC

Exynos3250 has additional 'sclk_adc' clock as following:
- 'sclk_adc' clock: special clock for ADC which provide clock to internal ADC

Exynos 4210/4212/4412 and Exynos5250/5420 has not included 'sclk_adc' clock
in FSYS_BLK. But, Exynos3250 based on Cortex-A7 has only included 'sclk_adc'
