iio: fix center temperature of bmc150-accel-core

2019-11-06T11:18:05+00:00

[ Upstream commit 6c59a962e081df6d8fe43325bbfabec57e0d4751 ]

The center temperature of the supported devices stored in the constant
BMC150_ACCEL_TEMP_CENTER_VAL is not 24 degrees but 23 degrees.

It seems that some datasheets were inconsistent on this value leading
to the error.  For most usecases will only make minor difference so
not queued for stable.

io: accel: kxcjk1013: restore the range after resume.

2019-04-27T07:34:42+00:00

commit fe2d3df639a7940a125a33d6460529b9689c5406 upstream.

On some laptops, kxcjk1013 is powered off when system enters S3. We need
restore the range regiter during resume. Otherwise, the sensor doesn't
work properly after S3.

iio: accel: kxcjk1013: Add KIOX010A ACPI Hardware-ID

2019-02-12T18:44:52+00:00

[ Upstream commit 7f6232e69539971cf9eaed07a6c14ab4a2361133 ]

Various 2-in-1's use KIOX010A and KIOX020A as HIDs for 2 KXCJ91008
accelerometers. The KIOX010A HID is for the one in the base and the
KIOX020A for the accelerometer in the keyboard.

Since userspace does not have a way yet to deal with (or ignore) the
accelerometer in the keyboard, this commit just adds the KIOX010A HID
for now so that display rotation will work.

iio: st_pressure: st_accel: pass correct platform data to init

2018-03-28T16:39:19+00:00

commit 8b438686a001db64c21782d04ef68111e53c45d9 upstream.

Commit 7383d44b added a pointer pdata which get set to the default
platform_data when non was defined in the device. But it did not
pass this pointer to the st_sensors_init_sensor call but still
used the maybe uninitialized platform_data from dev.

This breaks initialization when no platform_data is given and
the optional st,drdy-int-pin devicetree option is not set.

This commit fixes this.

iio: st_pressure: st_accel: Initialise sensor platform data properly

2018-03-24T10:00:15+00:00

[ Upstream commit 7383d44b84c94aaca4bf695a6bd8a69f2295ef1a ]

This patch fixes the sensor platform data initialisation for st_pressure
and st_accel device drivers. Without this patch, the driver fails to
register the sensors when the user removes and re-loads the driver.

1. Unload the kernel modules for st_pressure
$ sudo rmmod st_pressure_i2c
$ sudo rmmod st_pressure

2. Re-load the driver
$ sudo insmod st_pressure
$ sudo insmod st_pressure_i2c

iio: accel: bmc150: Always restore device to normal mode after suspend-resume

2017-08-16T20:43:20+00:00

commit e59e18989c68a8d7941005f81ad6abc4ca682de0 upstream.

After probe we would put the device in normal mode, after a runtime
suspend-resume we would put it back in normal mode. But for a regular
suspend-resume we would only put it back in normal mode if triggers
or events have been requested.  This is not consistent and breaks
reading raw values after a suspend-resume.

This commit changes the regular resume path to also unconditionally put
the device back in normal mode, fixing reading of raw values not working
after a regular suspend-resume cycle.

iio: accel: st_accel: fix LIS3LV02 reading and scaling

2017-01-12T10:39:21+00:00

commit 65e4345c8ef8811bbb4860fe5f2df10646b7f2e1 upstream.

The LIS3LV02 has a special bit that need to be set to get the
read values left aligned. Before this patch we get gibberish
like this:

iio_generic_buffer -a -c10 -n lis3lv02dl_accel
(...)
0.000000 -0.010042 -0.642688 19155832931907
0.000000 -0.010042 -0.642688 19155858751073

Which is because we read a raw value for 1g as 64 which is
the nominal 1024 for 1g shifted 4 bits to the left by being
right-aligned rather than left aligned.

Since all other sensors are left aligned, add some code to
set the special DAS (data alignment setting) bit to 1 so that
the right value is now read like this:

iio_generic_buffer -a -c10 -n lis3lv02dl_accel
(...)
0.000000 -0.147095 -10.120135 24761614364956
-0.029419 -0.176514 -10.120135 24761631624540

The scaling was weird as well: we have a gain of 1000 for 1g
and 3000 for 6g. I don't even remember how I came up with the
old values but they are wrong.
