Merge tag 'iio-for-4.17b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new device support, features and cleanup for IIO in the 4.17 cycle The uptick in staging cleanup is partly due to GSoC Applications process being underway and one of Daniel's tasks being to try cleaning up an IIO driver to move out of staging. Naturally there is some normal staging cleanup progress in here as well. New device support * Microchip mcp4018 - New driver supproting MCP4017, MCP4018 and MCP4019 digital pots. * On Semiconductor lv0104cs - New driver to support this ambient light sensor. Cleanup * axp20x_adc - remove a !! in favour of clear ternary operator. * ad2s1210 (staging cleanup) - Reorganise to avoid ending a line with [ - Remove some unnecessary defines. - Remove unsed variable. * ad5380 - Replace magic 0 with IIO_CHAN_INFO_RAW * ad5764 - Replace magic 0 with IIO_CHA_INFO_RAW * ad7150 (staging cleanup) - Align arguements with parenthesis. * ad7152 (staging cleanup) - Align arguements. * ad7746 (staging cleanup) - Align arguements. * ad7816 - Remove pointless void pointer cast. * ade7753 - Replace IIO_DEV_ATTR_CH_OFF with equivalent to avoid confusing checkpatch (this macro didn't really help anyway). Also drop the macro from the meter.h header. * ade7754 (staging cleanup) - Add names to funciton definition arguements. - Align arguements with open parenthesis where possible. * ade7758 (staging cleanup) - Remove __func__ from dev_dbg statements as provided by dynamic debug anyway. - Align arguements with open parenthesis where possible. * ade7759 (staging cleanup) - Replace IIO_DEV_ATTR_CH_OFF with equiavalent to avoid confusing checkpatch. * adis16201 (staging cleanup) - Headers in alphabetical order. - Blank lines before returns. * adis16209 (staging cleanup) - Headers in alphabetical order - Change some definition names to make them more meaningful (2 rounds of this). - Add explicit _REG prefix to register names to make them obviously different from fields within those registers. - Remove some superflous comments and group definitions better. - Use a switch statement to make it semantically obvious that we only have two options (rather than an unlimited 'else'). - Use sign_extent32 instead of open coding. * adt7316 (staging cleanup) - Move an export next to symbol. * bmc150 - drop redundant __func__ in dynamic debug. * ccs811 - Rename varaible to better reflect what it does. * cros_ec - Reduce sampling frequency before suspending to avoid preventing suspend. * dummy - Correct whitespace in Kconfig. - Add extra description in Kconfig. * ds1803 - Remove a VLA which we always know is 2 long. * hid-sensor-accel - Replace magic number 0 by IIO_CHAN_INFO_RAW. * hid-sensor-gyro - Replace magic number 0 by IIO_CHAN_INFO_RAW. * hid-sensor-light - Replace magic number 0 by IIO_CHAN_INFO_RAW. * hid-sensor-magn - Replace magic number 0 by IIO_CHAN_INFO_RAW. * lm3533 - Replace magic number 0 by IIO_CHAN_INFO_RAW * mlx90632 - Squash a smatch warning - no runtime effect. * stm32_dfsdm: - Cleanup the dt bindings. * sx9500 - Add GPIO ACPI mapping table to behave correctly when firmware doesn't provide the mapping. * tsl2x7x (staging cleanup) - Fix the proximity sensor functionality. - Remove platform data provided power functions. There are much better ways to do this these days. - Introduce some common functions to avoid various repititions. - Stop using mutex_trylock when mutex_lock and wait a bit is fine. - Improve error handling in various places. - Drop some 'Camel case' (which wasn't actually strickly camel case but was a bit odd. - Drop some _available sysfs attributes for things that don't exist (for particular supported parts).

Drop dependency on ARCH_LAYERSCAPE (which in turn depends on ARM64), thus allowing this driver to compile on all architectures supported by the fsl-mc bus driver. This was compile tested on: - powerpc (corenet_basic_defconfig, ppc64_defconfig) - x86 (i386_defconfig, x86_64_defconfig, needs CONFIG_OF) - arm64 (defconfig) Signed-off-by:

The bits for setting up the proximity diode were not setup correctly and this was causing the proximity sensor to not function correctly. This patch sets up the correct bit mask in tsl2x7x_chip_on() based on what the data sheet expects. From page 35 of the TSL2771 data sheet: https://ams.com/eng/content/download/250264/976045/file/TSL2771_DS000105_3-00.pdf - Bits 0-1 is the ALS gain control - Bits 2-3 is reserved (The proximity gain control on other tsl2x7x chips) - Bits 4-5 is the proximity diode select - Bits 6-7 is the LED drive strength tsl2x7x_chip_on() had the power and diode hardcoded, so these are extracted out into the settings so that these fields can be configured in the platform data. The default prox_gain is changed from 1 (2X gain) to 0 (1X gain) since the proximity gain control on the TSL2771, TMD2771, and other chips have these fields listed as reserved, and to write 0 into those bits. Verified that the proximity sensor now works correctly on a TSL2771 hooked up to a Raspberry Pi 2. Signed-off-by:

The tsl2771 and tmd2771 devices create the in_proximity0_calibscale_available sysfs attribute. These two particular devices do not support changing the proximity gain value on the chip so this patch removes that sysfs attribute. As expected, these two devices already did not create the IIO_CHAN_INFO_CALIBSCALE channel and proximity0_calibrate sysfs attribute. Page 38 of the tsl2772 data sheet shows that the proximity gain can be adjusted with bits 2-3 on the control register: https://ams.com/eng/content/download/291503/1066377/file/TSL2772_DS000181_2-00.pdf Page 35 of the tsl2771 and tmd2771 data sheets shows that bits 2-3 on the control register are reserved and changing the proximity gain is not supported: https://ams.com/eng/content/download/250264/976045/file/TSL2771_DS000105_3-00.pdf https://ams.com/eng/content/download/250283/976077/file/TMD2771_DS000177_2-00.pdfSigned-off-by:

Not all errors that occurred in tsl2x7x_get_prox() were correctly reported in the return value. This patch changes the error handling so that errors are now returned properly. Note that the ret variable is from the call to tsl2x7x_read_status(), and it already has the correct error check. The -EINVAL error code is for an unexpected value in the register. This patch also corrects an unnecessary word wrap in the call to le16_to_cpup() while changes are being made to this code. Signed-off-by:

The tsl2X7X_platform_data structure contains the platform_power, power_on, and power_off function pointers. These power management functions should not be in the platform data. These functions were likely used before the regulator framework was put in place. There are no users of these functions in the mainline kernel. Signed-off-by:

printk() is the raw way to print output and should be avoided. For drivers with defined "struct device object", dev_*macro() is prefer and for "struct netdevice object", netdev_*macro() is prefer over dev_*macro() to standardize the output format within the subsystem. If no "struct device object" is defined prefer pr_*macro() over printk(). This patch Replace printk having a log level with the appropriate output format according to the order of preference.

There is no need for the calls to BUG_ON() in this driver, which are used to check if mbo or mbo->context are NULL; mbo is never NULL, and if mbo->context is NULL it would have already been dereferenced and oopsed before reaching the BUG_ON(). Signed-off-by:

Usually, functions responsible for reading raw data typically relies on values from iio_chan_info_enum to correctly identify the type of data to be read. There is a set of a device driver that uses the magic number 0 instead of IIO_CHAN_INFO_RAW. This patch improves the readability by replaces the magic number 0 for the appropriate IIO_CHAN_INFO_RAW in six devices driver in the IIO subsystem. Signed-off-by:
