* iio:pressure:ms5611 Fix buffer element alignmentJonathan Cameron2020-07-051-3/+8
| | | | | | | | | | | | | | | | | | | | One of a class of bugs pointed out by Lars in a recent review. iio_push_to_buffers_with_timestamp assumes the buffer used is aligned to the size of the timestamp (8 bytes). This is not guaranteed in this driver which uses an array of smaller elements on the stack. Here there is no data leak possibility so use an explicit structure on the stack to ensure alignment and nice readable fashion. The forced alignment of ts isn't strictly necessary in this driver as the padding will be correct anyway (there isn't any). However it is probably less fragile to have it there and it acts as documentation of the requirement.

* iio: bmp280: fix compensation of humidityAndreas Klinger2020-05-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | Limit the output of humidity compensation to the range between 0 and 100 percent. Depending on the calibration parameters of the individual sensor it happens, that a humidity above 100 percent or below 0 percent is calculated, which don't make sense in terms of relative humidity. Add a clamp to the compensation formula as described in the datasheet of the sensor in chapter 4.2.3. Although this clamp is documented, it was never in the driver of the kernel. It depends on the circumstances (calibration parameters, temperature, humidity) if one can see a value above 100 percent without the clamp. The writer of this patch was working with this type of sensor without noting this error. So it seems to be a rare event when this bug occures.

* iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_triggerAlexandru Ardelean2020-05-101-14/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main intent here is to get rid of the iio_buffer_set_attrs() helper, or at least rework it's usage a bit. The problem with that helper is that it needs a pointer to the buffer, which makes supporting multiple buffers per IIO device a bit more cumbersome. The hid_sensor_setup_trigger() is pretty much used in the same way: - iio_triggered_buffer_setup() gets called before - then hid_sensor_setup_trigger() and hid_sensor_setup_batch_mode() gets called which may attach some fifo attributes This change merges the 2 together under the hid_sensor_setup_trigger() function. Only the &iio_pollfunc_store_time is passed to all devices, so it's not even required to pass it explicitly outside of the common hid_sensor_setup_trigger() function. Moving the devm_iio_triggered_buffer_setup/cleanup() calls into the common place code can help the rework of the buffer code, since it is in one place. One detail of the change is that there are 2 drivers that use devm_iio_triggered_buffer_setup(). That function gets implicitly replaced with iio_triggered_buffer_setup()/cleanup(), but since all drivers call both hid_sensor_setup_trigger9) & hid_sensor_remove_trigger() trigger, the iio_triggered_buffer_cleanup() piggy backs on the hid_sensor_remove_trigger() call, which should cover the cleanup.

The usual mixed backs of new device support being added to drivers, long term reworks continuing and little per driver cleanups and features. Also a few trivial counter subsystem tidy ups on behalf of William. Core new feature * Device label support. A long requested feature no one got around to implementing before. Allows DT based provision of a 'label' that identifies a device uniquely within a system. This differs from existing 'name' which is meant to be the part number. New device support * ingenic-adc - Support for the JZ4770 SoC ADC including bindings. * inv_mpu6050 - Add support for magnetometer in MPU925x parts. Fiddly to do as this is actually a separate device sitting inside the package, but with the master device being able to schedule reads etc. Will only run if the auxiliary bus is not in use for any other devices. Features * ad7192 - Userspace calibration controls to do zero and full scale. * st_lsm6dsx - Enable latched interrupts by default for sensors events with related clear. - Motion events and related wakeup source. This needed quite a bit of refactoring as well. Cleanups and minor features * ad7192 - sysfs ABI docs * ad7949 - Remove code to readback configuration word as driver never actually enabled it. - Fix incorrect xfer length. Not actually known to cause problems other than wasted bus usage. * adis16080 - Replace core mlock usage with local lock with more appropriate scope. * adis16130 - Remove pointless mlock usage. * adis16240 - Remove include of gpio.h as no gpio usage. * atlas-ph-sensor - Improve logical ordering of buffer predisable / postenable functions. This is part of a longer term rework Alexandru is driving towards. * bh1750 - Fix up a static compiler warning and make the code more readable. - yaml conversion of binding + MAINTAINERS entry. * bmp280 - Drop a stray newline. * cm36651 - Drop a redundant assignment * itg3200 - Alignment cleanup. * max31856 - Add missing of_node and parent references, useful to identify the device. * sc27xx_adc - Use devm_hwspin_lock_request_specific rather than local rolled version. * stm32-lptimer counter - kernel-doc warning. * stm32-timer counter - kernel-doc warning. - Alignment cleanup. * sx9500 - Improve logical ordering of buffer predisable / postenable functions.

For example, we have a linux/mfd/cros_ec.h include that exports the interface implemented in platform/chrome/cros_ec_proto.c. Or we have a linux/mfd/cros_ec_commands.h file that is non related to the multifunction device (in the sense that is not exporting any function of the mfd device). This causes crossed includes between mfd and platform/chrome subsystems and makes the code difficult to read, apart from creating 'curious' situations where a platform/chrome driver includes a linux/mfd/cros_ec.h file just to get the exported functions that are implemented in another platform/chrome driver. In order to have a better separation on what the cros-ec multifunction driver does and what the cros-ec core provides move and rework the affected includes doing: - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c driver from include/linux/mfd/cros_ec.h to a new file include/linux/platform_data/cros_ec_proto.h - Update all the drivers with the new includes, so - Drivers that only need to know about the protocol include - linux/platform_data/cros_ec_proto.h - linux/platform_data/cros_ec_commands.h - Drivers that need to know about the cros-ec mfd device also include - linux/mfd/cros_ec.h Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mark Brown <broonie@kernel.org> Acked-by: Wolfram Sang <wsa@the-dreams.de> Acked-by: Neil Armstrong <narmstrong@baylibre.com> Acked-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Acked-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Acked-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Acked-by: Sebastian Reichel <sebastian.reichel@collabora.com> Acked-by: Chanwoo Choi <cw00.choi@samsung.com> Reviewed-by: Gwendal Grignou <gwendal@chromium.org> Tested-by: Gwendal Grignou <gwendal@chromium.org> Series changes: 3 - Fix dereferencing pointer to incomplete type 'struct cros_ec_dev' (lkp) Signed-off-by: Lee Jones <lee.jones@linaro.org>
