* iio: remove explicit IIO device parent assignmentAlexandru Ardelean2020-06-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

* 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.

| | | | | | | | | | | | | | | | | | This patch affects BME280 and BMP280. The readout of the calibration data is moved to the probe function. Each sensor data access triggered reading the full calibration data before this patch. According to the datasheet, Section 4.4.2., the calibration data is stored in non-volatile memory. Since the calibration data does not change, and cannot be changed by the user, we can reduce bus traffic by reading the calibration data once. Additionally, proper organization of the data types enables removing some odd casts in the compensation formulas.

It is not configurable so the st_magn core was assuming it didn't exist and so wasn't consuming interrupts resulting in an unhandled interrupt. * stm32-adc - off by one error on max channels checking. * stm32-timer - preset should not be buffered - reorganising register writes avoids this. - fix a corner case in which write preset goes wrong when a timer is used first as a trigger then as a counter with preset. Odd case but you never know. * ti-ads1015 - Fix setting of comparator polarity by fixing bitfield definition. * twl4030 - Error path handling fix to cleanup in event of regulator registration failure. - Disable the vusb3v1 regulator correctly in error handling - Don't paper over a regulator enable failure.
| | * IIO: BME280: Updates to Humidity readings need ctrl_reg write!Colin Parker2017-09-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ctrl_reg register needs to be written after any write to the humidity registers. The value written to the ctrl_reg register does not necessarily need to change, but a write operation must occur. The regmap_update_bits functions will not write to a register if the register value matches the value to be written. This saves unnecessary bus operations. The change in this patch forces a bus write during the chip_config operation by switching to regmap_write_bits. This will fix issues where the Humidity Sensor Oversampling bits are not updated after initialization.

Note there is a misc driver drop in here given we have support in IIO and the feeling is no one will care. A large part of this series is a boiler plate removal series avoiding the need to explicitly provide THIS_MODULE in various locations. It's very dull but touches all drivers. New device support * ad5446 - add ids to support compatible parts DAC081S101, DAC101S101, DAC121S101. - add the dac7512 id and drop the misc driver as feeling is no one is using it (was introduced for a board that is long obsolete) * mt6577 - add bindings for mt2712 which is fully compatible with other supported parts. * st_pressure - add support for LPS33HW and LPS35HW with bindings (ids mostly). New features * ccs811 - Add support for the data ready trigger. * mma8452 - remove artifical restriction on supporting multiple event types at the same time. * tcs3472 - support out of threshold events Core and tree wide cleanup * Use macro magic to remove the need to provide THIS_MODULE as part of struct iio_info or struct iio_trigger_ops. This is similar to work done in a number of other subsystems (e.g. i2c, spi). All drivers are fixed and then the fields in these structures are removed. This will cause build failures for out of tree drivers and any new drivers that cross with this work going into the kernel. Note mostly done with a coccinelle patch, included in the series on the mailing list but not merged as the fields no longer exist in the structures so the any hold outs will cause a build failure. Cleanups * ads1015 - avoid writing config register when it doesn't change. - add 10% to conversion wait time as it seems it is sometimes a little small. * ade7753 - replace use of core mlock with a local lock. This is part of a long term effort to make the use of mlock opaque and single purpose. * ade7759 - expand the use of buf_lock to cover previous mlock cases. This is a slightly nicer solution to the same issue as in ade7753. * cros_ec - drop an unused variable * inv_mpu6050 - add a missing break in a switch for consistency - not actual bug, - make some local arrays static to save on object code size. * max5481 - drop manual setting of the spi module owner as handled by the spi core. * max5487 - drop manual setting of the spi module owner as handled by the spi core. * max9611 - drop explicit setting of the i2c module owner as handled by the i2c core. * mcp320x - speed up reads on single channel devices, - drop unused of_device_id data elements, - document the struct mcp320x, - improve binding docs to reflect restrictions on spi setup and to make it explicit that the reference regulator is needed. * mma8452 - symbolic to octal permissions, - unsigned to unsigned int. * st_lsm6dsx - avoid setting odr values multiple times, - drop config of LIR as it is only ever set to the existing defaults, - drop rounding configuration as it only ever matches the defaults. * ti-ads8688 - drop manual setting of the spi module owner as handled by the spi core. * tsl2x7x - constify the i2c_device_id, - cleanup limit checks to avoid static checker warnings (and generally have nicer code).

| | | | | | | | | | | | | | | | | | | | | | | This patch mimics the SPI functionality found in the misc driver in drivers/misc/bh085-spi.c to make it possible to reuse the existing BMP280/BMP180/BMP085 driver with all clients of the other driver. The adoption is straight-forward since like the other driver, it is a simple matter of using regmap. This driver is also so obviously inspired/copied from the old misc driver in drivers/misc/bmp085.c that I just took the liberty to add in the authors of the other drivers + self in the core driver file. The MISC driver also supports a variant named "BMP181" so include that here to be complete in comparison to the old driver. The bus mapping code for SPI was written by Akinobu Mita.
