2020-07-07iio: light: add missing vcnl4040 of_compatibleMarco Felsch
commit 7fd1c2606508eb384992251e87d50591393a48d0 upstream. Commit 5a441aade5b3 ("iio: light: vcnl4000 add support for the VCNL4040 proximity and light sensor") added the support for the vcnl4040 but forgot to add the of_compatible. Fix this by adding it now.

2020-07-07iio: light: fix vcnl4000 devicetree hooksMarco Felsch
commit 1436a78c63495dd94c8d4f84a76d78d5317d481b upstream. Since commit ebd457d55911 ("iio: light: vcnl4000 add devicetree hooks") the of_match_table is supported but the data shouldn't be a string. Instead it shall be one of 'enum vcnl4000_device_ids'. Also the matching logic for the vcnl4020 was wrong. Since the data retrieve mechanism is still based on the i2c_device_id no failures did appeared till now.

2020-06-24iio: vcnl4000: Fix i2c swapped word reading.Mathieu Othacehe
commit 18dfb5326370991c81a6d1ed6d1aeee055cb8c05 upstream. The bytes returned by the i2c reading need to be swapped unconditionally. Otherwise, on be16 platforms, an incorrect value will be returned. Taking the slow path via next merge window as its been around a while and we have a patch set dependent on this which would be held up.

2020-06-01iio: si1133: read 24-bit signed integer for measurementMaxime Roussin-Bélanger
commit 328b50e9a0ad1fe8accdf8c19923deebab5e0c01 upstream. The chip is configured in 24 bit mode. The values read from it must always be treated as is. This fixes the issue by replacing the previous 16 bits value by a 24 bits buffer. This changes affects the value output by previous version of the driver, since the least significant byte was missing. The upper half of 16 bit values previously output are now the upper half of a 24 bit value.

2020-05-21iio: light: vcnl4000: update sampling periods for vcnl4200Tomas Novotny
commit b42aa97ed5f1169cfd37175ef388ea62ff2dcf43 upstream. Vishay has published a new version of "Designing the VCNL4200 Into an Application" application note in October 2019. The new version specifies that there is +-20% of part to part tolerance. This explains the drift seen during experiments. The proximity pulse width is also changed from 32us to 30us. According to the support, the tolerance also applies to ambient light. So update the sampling periods. As the reading is blocking, current users may notice slightly longer response time.

commit 2ca5a8792d617b4035aacd0a8be527f667fbf912 upstream. Vishay has published a new version of "Designing the VCNL4200 Into an Application" application note in October 2019. The new version specifies that there is +-20% of part to part tolerance. Although the application note is related to vcnl4200, according to support the vcnl4040's "ASIC is quite similar to that one for the VCNL4200". So update the sampling periods (and comment), including the correct sampling period for proximity. Both sampling periods are lower. Users relying on the blocking behaviour of reading will get proximity measurements much earlier.

commit bc80573ea25bb033a58da81b3ce27205b97c088e upstream. According to the data sheet the ambient sensor's scale is 0.12 lux/step (not 0.024 lux/step as used by vcnl4200) when the integration time is 80ms. The integration time is currently hardcoded in the driver to that value.

2020-02-24iio: light: bh1750: Resolve compiler warning and make code more readableKrzysztof Wilczynski
commit f552fde983d378e7339f9ea74a25f918563bf0d3 upstream. Separate the declaration of struct bh1750_chip_info from definition of bh1750_chip_info_tbl[] in a single statement as it makes the code hard to read, and with the extra newline it makes it look as if the bh1750_chip_info_tbl[] had no explicit type. This change also resolves the following compiler warning about the unusual position of the static keyword that can be seen when building with warnings enabled (W=1): drivers/iio/light/bh1750.c:64:1: warning: ‘static’ is not at beginning of declaration [-Wold-style-declaration] Related to commit 3a11fbb037a1 ("iio: light: add support for ROHM BH1710/BH1715/BH1721/BH1750/BH1751 ambient light sensors").

The MAX44009 is a low-power ambient light sensor from Maxim Integrated. It differs from the MAX44000 in that it doesn't have proximity sensing and that it requires far less current (1 micro-amp vs 5 micro-amps). The register mapping and feature set between the two are different enough to require a new driver for the MAX44009.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: First set of new device support, features and cleanups for IIO in the 4.21 cycle Along with the headline feature of 5 new drivers, we have the substantial addition of auxilliary sensor support on the lsm6sdx parts for ST. There has also been a good set of staging cleanup in this period with more underway. An ever increasing number of devices supported with just a new ID which is a good sign that at least some manufacturers are continuing to stabilise their interfaces. New device support, * ad7124 - New driver supporting Analog Devices' ad7124-4 and ad7124-8 parts with the inevitable DT binding. * ad7949 - New driver supporting Analog Devices' ad7949, AD7682 and AD7689 ADCs. * rm3100 - New driver supporting PNIs RM3100 magnometer with bindings and vendor prefix. * ti-dac7311 - New driver supporting DAC7311, DAC6311 and DAC5311 TI DACs, with DT bindings. * vcnl5035 - New driver supporting the light sensor part of the VCNL4035, with DT bindings Features, * bindings - Add a generic ADC channel binding as we keep reinventing this wheel. * adc128s052 - Add IDs for additional pin compatible parts. - Add APCI ID seen on E3940 UP squared boards. * ad_sigma_delta - Allow for custom data register overiding default. * kxcjk1013 - Add KIOX0009 ACPI ID as seen on the Acer One 10. * lsm6dsx - Rework leading to... - External sensor support using the built in I2C master. - Initial support for a slave lis2mdl magnetometer. * meson-saradc - Add temperature sensor support and bindings. * st_magn - New ID for lsm9dsl_magn with bindings - New ID for lis3de accelerometer * tpl0102 - Add supprot for IIO_AVAIL_RANGE to report the range available from this device to userspace and in kernel users. Cleanups and minor fixes * tools - Allow outside specification of CFLAGS * ad2s90 - Handle and spi_read error. - Handle spi_setup failure - Drop a pointless assignment. - Prevent a potentail race by moving device registration to after all other setup. - Add missing scale attribute. - Add a sanity check on channel type before trying to read it. * ad2s1210 - Move to modern gpio descriptors. - Drop a gpioin flag which made no sense as far as we can tell. - Add dt table (bindings doc to follow when this is ready for moving out of staging). * ad5933 - Drop camel-case naming of ext_clk_hz. - White space fixes. * ad7150 - Local variable to shorten overly long line. - Alignment and line break fixes. * ad7280a - Handle an error path that was previously ignored. - Use crc8.h to build the crc table replacing custom code. - Avoid unecessary cast. - Power down the device if an error happens in probe - Use devm routines to simplify probe and remove. * ad7606 - Alignment fixes. * ad7780 - This worked as long as by coincidence an uninitialized value was 0. Lets not rely on that. - Ensure gain update is only used with the ad778x chips that actually support it. - Tidy up pattern mask generation. - Read regulator when scale is requested (which should be infrequent) as it might have changed from initialization. * ad7816 - Move to modern gpio descriptors - Don't use a busy_pin for ad7818 as there isn't one. - Ensure RD/WR and CONVST pins are outputs (previously they were brought up as inputs which doesn't seem to make any sense) - DT id table. * adc128s052 - SPDX * adt7316 - Alignment fix. - Fix data reading. When using I2C the driver never actually used the value read. This has been broken a very long time hence no rush to fix it now + the driver is undergoing a lot of cleanup. - Sanity check that the i2c read didn't fail to actually read anything. * dpot-dac - Mark a switch full through with slightly different text so that gcc doesn't warn on it. * gyro-adc - Fix a wrong file in the MAINTAINERS entry and add binding doc to the listed files. * ina2xx - Add some early returns to clarify error paths in switch. * lsm6dsx - MAINTAINERS entry. * max11100 - SPDX * max9611 - SPDX * mcp4131 - use of_device_get_match_data in preference to spi_get_device_id approach. * rcar-adc - SPDX * sc27xx - Add ADC conversion timeout support to avoid possible fault. * ssp_sensors - Don't free managed resources manually. * st-magn - Add a comment to avoid future confusion over when to use -magn postfix (on multi chip in package parts) - Add BDU register for LIS3MDL where it seems to have been missed. * st-sensors - Minor spelling, grammar etc fixes. * tpl0102 - Use a pointer rather than an index of an array to improve conciseness. * tag 'iio-for-4.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (80 commits) Staging: iio: adt7316: Add an extra check for 'ret' equals to 0 Staging: iio: adt7316: Fix i2c data reading, set the data field dt-bindings: iio: adc: Add docs for ad7124 iio: adc: Add ad7124 support dt-bindings: iio: adc: Add common ADCs properties to a separate file iio: ad_sigma_delta: Allow to provide custom data register address staging: iio: ad7816: Add device tree table. iio: imu: st_lsm6dsx: add entry in MAINTAINERS file iio: potentiometer: mcp4131: use of_device_get_match_data() staging: iio: adc: ad7280a: use devm_* APIs staging: iio: adc: ad7280a: power down the device on error in probe dt-bindings: iio: imu: st_lsm6dsx: add support to i2c pullup resistors iio: imu: st_lsm6dsx: add hw FIFO support to i2c controller iio: imu: st_lsm6dsx: add st_lsm6dsx_push_tagged_data routine iio: imu: st_lsm6dsx: add i2c embedded controller support iio: imu: st_lsm6dsx: introduce st_lsm6dsx_sensor_set_enable routine iio: imu: st_lsm6dsx: introduce ST_LSM6DSX_ID_EXT sensor ids iio: imu: st_lsm6dsx: remove static from st_lsm6dsx_set_watermark iio: imu: st_lsm6dsx: reload trimming parameter at bootstrap iio: imu: st_lsm6dsx: introduce locked read/write utility routines ...

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.

2018-09-07regmap: split up regmap_config.use_single_rwDavid Frey
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.

VCNL4200 is an integrated long distance (up to 1500mm) proximity and ambient light sensor. The support is very basic. There is no configuration of proximity and ambient light sensing yet. Only the reading of both measured values is done. The reading of ambient light and proximity values is blocking. If you request a new value too early, the driver waits for new value to be ready.
