Merge tag 'staging-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Browse Source 
Pull staging/IIO updates from Greg KH:
 "Here's the "big" staging/iio pull request for 4.10-rc1.

  Not as big as 4.9 was, but still just over a thousand changes. We
  almost broke even of lines added vs. removed, as the slicoss driver
  was removed (got a "clean" driver for the same hardware through the
  netdev tree), and some iio drivers were also dropped, but I think we
  ended up adding a few thousand lines to the source tree in the end.
  Other than that it's a lot of minor fixes all over the place, nothing
  major stands out at all.

  All of these have been in linux-next for a while. There will be a
  merge conflict with Al's vfs tree in the lustre code, but the
  resolution for that should be pretty simple, that too has been in
  linux-next"

What: /sys/bus/iio/devices/iio:deviceX/in_altvoltageY_invert
Date: October 2016
KernelVersion: 4.9
Contact: Peter Rosin <peda@axentia.se>
Description:
The DAC is used to find the peak level of an alternating
voltage input signal by a binary search using the output
of a comparator wired to an interrupt pin. Like so:
_
| \
input +------>-------|+ \
| \
.-------. | }---.
| | | / |
| dac|-->--|- / |
| | |_/ |
| | |
| | |
| irq|------<-------'
| |
'-------'
The boolean invert attribute (0/1) should be set when the
input signal is centered around the maximum value of the
dac instead of zero. The envelope detector will search
from below in this case and will also invert the result.
The edge/level of the interrupt is also switched to its
opposite value.

Description:
Read-only attribute that indicates whether the counter for
channel Y is counting up or down.
What: /sys/bus/iio/devices/iio:deviceX/in_countY_count_mode
KernelVersion: 4.9
Contact: linux-iio@vger.kernel.org
Description:
Count mode for channel Y. Four count modes are available:
normal, range limit, non-recycle, and modulo-n. The preset value
for channel Y is used by the count mode where required.
Normal:
Counting is continuous in either direction.
Range Limit:
An upper or lower limit is set, mimicking limit switches
in the mechanical counterpart. The upper limit is set to
the preset value, while the lower limit is set to 0. The
counter freezes at count = preset when counting up, and
at count = 0 when counting down. At either of these
limits, the counting is resumed only when the count
direction is reversed.
Non-recycle:
Counter is disabled whenever a 24-bit count overflow or
underflow takes place. The counter is re-enabled when a
new count value is loaded to the counter via a preset
operation or write to raw.
Modulo-N:
A count boundary is set between 0 and the preset value.
The counter is reset to 0 at count = preset when
counting up, while the counter is set to the preset
value at count = 0 when counting down; the counter does
not freeze at the bundary points, but counts
continuously throughout.

Contact: linux-iio@vger.kernel.org
Description:
Read-only attribute that indicates whether excessive noise is
present at the channel Y count inputs in quadrature clock mode;
irrelevant in non-quadrature clock mode.
What: /sys/bus/iio/devices/iio:deviceX/in_countY_preset
KernelVersion: 4.9
Contact: linux-iio@vger.kernel.org
Description:
If the counter device supports preset registers, the preset
count for channel Y is provided by this attribute.
What: /sys/bus/iio/devices/iio:deviceX/in_countY_quadrature_mode
KernelVersion: 4.9
Contact: linux-iio@vger.kernel.org
Description:
Configure channel Y counter for non-quadrature or quadrature
clock mode. Selecting non-quadrature clock mode will disable
synchronous load mode. In quadrature clock mode, the channel Y
scale attribute selects the encoder phase division (scale of 1
selects full-cycle, scale of 0.5 selects half-cycle, scale of
0.25 selects quarter-cycle) processed by the channel Y counter.
Non-quadrature:
The filter and decoder circuit are bypassed. Encoder A
input serves as the count input and B as the UP/DOWN
direction control input, with B = 1 selecting UP Count
mode and B = 0 selecting Down Count mode.
Quadrature:
Encoder A and B inputs are digitally filtered and
decoded for UP/DN clock.

non-synchronous load mode.
What: /sys/bus/iio/devices/iio:deviceX/in_indexY_synchronous_mode
KernelVersion: 4.9
Contact: linux-iio@vger.kernel.org
Description:
Configure channel Y counter for non-synchronous or synchronous
load mode. Synchronous load mode cannot be selected in
non-quadrature clock mode.
Non-synchronous:
A logic low level is the active level at this index
input. The index function (as enabled via
set_to_preset_on_index) is performed directly on the
active level of the index input.
Synchronous:
Intended for interfacing with encoder Index output in
quadrature clock mode. The active level is configured
via index_polarity. The index function (as enabled via
set_to_preset_on_index) is performed synchronously with
the quadrature clock on the active level of the index
input.

Description:
From ISL29018 Data Sheet (FN6619.4, Oct 8, 2012) regarding the
infrared suppression:
Scheme 0, makes full n (4, 8, 12, 16) bits (unsigned) proximity
detection. The range of Scheme 0 proximity count is from 0 to
2^n. Logic 1 of this bit, Scheme 1, makes n-1 (3, 7, 11, 15)
bits (2's complementary) proximity_less_ambient detection. The
range of Scheme 1 proximity count is from -2^(n-1) to 2^(n-1).
The sign bit is extended for resolutions less than 16. While
Scheme 0 has wider dynamic range, Scheme 1 proximity detection
is less affected by the ambient IR noise variation.
0 Sensing IR from LED and ambient
1 Sensing IR from LED with ambient IR rejection
