iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers

2018-11-16T11:42:12+00:00

Before this commit sensor_hub_input_attr_get_raw_value() failed to take
the signedness of 16 and 8 bit values into account, returning e.g.
65436 instead of -100 for the z-axis reading of an accelerometer.

This commit adds a new is_signed parameter to the function and makes all
callers pass the appropriate value for this.

While at it, this commit also fixes up some neighboring lines where
statements were needlessly split over 2 lines to improve readability.

Jonathan writes:

First set of IIO fixes for the 4.19 cycle.

* ad9523
  - sysfs write should return the number of characters used or an error, not
    0 which could result in an infinite loop in userspace.
* lsm6dsx
  - Fix computation of length when updating the watermark to include
    timestamps avoiding the watermark being set earlier than intended.
* maxim_thermocouple
  - Revert a patch adding the max31856 as it's not actually compatible with
    the register set that this driver supports.
* si1133
  - Fix an impossible value check so we don't always error out whether the
    passed in value is good or bad.

regmap: split up regmap_config.use_single_rw

2018-09-07T12:03:55+00:00

Split regmap_config.use_single_rw into use_single_read and
use_single_write. This change enables drivers of devices which only
support bulk operations in one direction to use the regmap_bulk_*()
functions for both directions and have their bulk operation split into
single operations only when necessary.

Update all struct regmap_config instances where use_single_rw==true to
instead set both use_single_read and use_single_write. No attempt was
made to evaluate whether it is possible to set only one of
use_single_read or use_single_write.

Revert "iio: temperature: maxim_thermocouple: add MAX31856 part"

2018-09-02T09:13:06+00:00

This reverts commit 535fba29b3e1afef4ba201b3c69a6992583ec0bd.

Seems the submitter (er me, hang head in shame) didn't look at the datasheet
enough to see that the registers are quite different.

This needs to be reverted because a) would never work b) to open it  be added
to a Maxim RTDs (Resistance Temperature Detectors) under development by author

i2c: remove i2c_lock_adapter and use i2c_lock_bus directly

2018-07-12T22:09:37+00:00

The i2c_lock_adapter name is ambiguous since it is unclear if it
refers to the root adapter or the adapter you name in the argument.
The natural interpretation is the adapter you name in the argument,
but there are historical reasons for that not being the case; it
in fact locks the root adapter. Just remove the function and force
users to spell out the I2C_LOCK_ROOT_ADAPTER name to indicate what
is really going on. Also remove i2c_unlock_adapter, of course.

This patch was generated with

git grep -l 'i2c_\(un\)\?lock_adapter' \
| xargs sed -i 's/i2c_\(un\)\?lock_adapter(\([^)]*\))/'\
'i2c_\1lock_bus(\2, I2C_LOCK_ROOT_ADAPTER)/g'

followed by white-space touch-up.

iio temperature/mlx90632: silence a static checker warning

This shouldn't affect runtime at all, but Smatch complains that we
should check if mlx90632_read_ambient_raw() otherwise we
"ambient_new_raw" can be uninitialized.

2017-11-14T04:53:28+00:00

Pull staging and IIO updates from Greg KH:
 "Here is the "big" staging and IIO driver update for 4.15-rc1.

  Lots and lots of little changes, almost all minor code cleanups as the
  Outreachy application process happened during this development cycle.
  Also happened was a lot of IIO driver activity, and the typec USB code
  moving out of staging to drivers/usb (same commits are in the USB tree
  on a persistent branch to not cause merge issues.)

  Overall, it's a wash, I think we added a few hundred more lines than
  removed, but really only a few thousand were modified at all.

  All of these have been in linux-next for a while. There might be a
  merge issue with Al's vfs tree in the pi433 driver (take his changes,
  they are always better), and the media tree with some of the odd
  atomisp cleanups (take the media tree's version)"
