2021-07-19iio: light: tcs3414: convert probe to device-managed routinesAlexandru Ardelean1-29/+19
This change converts the driver to use only device-managed init routines in the probe function of the driver. This way, we no longer need the tcs3414_remove() hook. We still need to keep the i2c_set_clientdata() call, as that's being used for the PM routines. And lastly, a devm_add_action_or_reset() hook is added to call the powerdown handler when the chip is uninitialized or the probe fails.

2021-07-17iio: light: adjd_s311: convert probe to device-managed functionsAlexandru Ardelean1-25/+3
Now that the driver's buffer is stored on the adjd_s311_data private object, the driver is a simple conversion to use only device-managed functions in the probe. The iio_triggered_buffer_setup() and iio_device_register() functions are the only ones needing conversion. And i2c_set_clientdata() is no longer required.

2021-07-17iio: light: adjd_s311: move buffer on adjd_s311_data objectAlexandru Ardelean1-19/+6
This change moves the entire buffer on the private adjd_s311_data type. Since the device has 4 channels, it's not a big waste to just allocate the maximum possible buffer and use only what's needed. This is in contrast with free-ing and re-allocating the buffer on the update_scan_mode hook. Since the driver pushes buffer data with iio_push_to_buffers_with_timestamp(), the buffer must also include a 64-bit buffer for the timestamp, for each sample-set. With this change, the adjd_s311_update_scan_mode() is no longer needed.

2021-07-13iio: hid-sensors: bind IIO channels alloc to device objectAlexandru Ardelean2-14/+8
Some HID drivers use devm_kmemdup() already to clone the template IIO channels information and update it. However, there are still some drivers that kmemdup() and kfree() the channels. This change converts them to use devm_kmemdup() and bind the life-time of this allocated object to the parent device object (in these drivers).

2021-06-13iio: ltr501: mark register holding upper 8 bits of ALS_DATA{0,1} and PS_DATA as volatile, tooMarc Kleine-Budde1-0/+6
The regmap is configured for 8 bit registers, uses a RB-Tree cache and marks several registers as volatile (i.e. do not cache). The ALS and PS data registers in the chip are 16 bit wide and spans two regmap registers. In the current driver only the base register is marked as volatile, resulting in the upper register only read once. Further the data sheet notes: | When the I2C read operation starts, all four ALS data registers are | locked until the I2C read operation of register 0x8B is completed. Which results in the registers never update after the 2nd read. This patch fixes the problem by marking the upper 8 bits of the ALS and PS registers as volatile, too.

2021-05-17iio: core: move @id from struct iio_dev to struct iio_dev_opaqueJonathan Cameron5-5/+7
Continuing from Alexandru Ardelean's introduction of the split between driver modifiable fields and those that should only be set by the core. This could have been done in two steps to make the actual move after introducing iio_device_id() but there seemed limited point to that given how mechanical the majority of the patch is. Includes fixup from Alex for missing mxs-lradc-adc conversion.

2021-05-10iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERAlexandru Ardelean1-2/+0
During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger"), the iio_triggered_buffer_{setup,cleanup}() functions got moved under the hid-sensor-trigger module. The above change works fine, if any of the sensors get built. However, when only the common hid-sensor-trigger module gets built (and none of the drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced. Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets selected. All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

Jonathan writes: 1st set of IIO/counter device support, features and cleanup in the 5.13 cycle Big set in here from Alexandru Ardelean enabling multiple buffer support. This includes providing a new directory per buffer that combines what was previously in buffer/ and scan_elements/. Old interfaces still in place for compatiblity. Note immuatable branch for scmi patches to allow for some significant rework going on in that subsystem. Merge required updating to reflect some changes in IIO. Late rebase to fix some wrong fixes tags due to some earlier rebases made necessary by messing up the immutable branch. IIO New Device Support * adi,ad5686 - Add info to support AD5673R and AD5677R * bosch,bmi088 - New driver supporting this accelerometer + gyroscope * cros_ec_mkbp - New driver for this proximity sensor that exposes a 'front' sensor. Very simple switch like device, but driver allows it to share interface with more sophisticated proximity sensors. * iio_scmi - New driver to support ARM SCMI protocol to expose underlying accelerometers and gyroscopes via this firmware interface. * st,st_magn - Add ID for IISMDC magnetometer. * ti,ads131e0 - New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs Counter New Device Support * IRQ or GPIO based counter - New driver for a conceptually simple counter that uses interrupts to perform the count. Features * core - Dual buffer supprt including: Various helpers to centralize handling of bufferer related elements. Document existing and new IOCTLs Register the IIO chrdev only if it can actually be used for anything. Rework attribute group creation in the core (lots of patches) Merge buffer/ and scan_elements/ entries into one list + maintain backwards compatible set. Introduce the internal logic and IOCTL to allow multiple buffers + access to an anon FD per buffer to actually read from it. Tidy up tools/iio/iio_generic_buffer and switch to new interfaces. Update ABI docs. A few follow up fixes, unsuprising as this was a huge bit of rework. - Move common case setting of trig->parent to the core. - Provide an iio_read_channel_processed_scale() to avoid loss of precision from iio_read_channel_processed() then applying integer scale. Use it in ntc_thermistor driver in hwmon. - Allow drivers to specify labels from elsewhere than DT. Use it for bmc150 and kxcjk-1013 labels related to position on 2 in one tablets. - Document label usage for proximity and accelerometer sensors. - Some local variable renames for consistency tools - Add -a parameter to iio_event_monitor to allow autoenabling of events. * acpi_als - Add trigger support for devices that don't support notification method. * adi,ad7124 - Allow more than 8 channels. This is a complex little device, but is capable of supporting up to 16 channels if the share certain configuration settings. * hrtimer-trigger - Support sampling frequency below 1Hz. * mediatek,mt8195-auxadc - Add compatible to binding docs (always also includes mt8173) * st,stm32-adc - Enable timetamps when not using DMA. * vishay,vcnl3020 - Sampling frequency control. Cleanup and minor fixes: * treewide - Use some getter and setter functions instead of opencoding. - Set of fixes for pointless casts in various drivers. - Avoid wrong kernel-doc marking on comment blocks. - Fix various other minor kernel-doc issues shown by W=1 * core - Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts. - Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0 - Add unit tests for iio_format_value() * docs - Fix formatting/typos in iio_configfs.rst and buffers.rst - Add documentation of index in buffers.rst - Fix scan element description - Avoid some issues with HTML generation from ABI docs by moving duplicated defintions to more generic files. - Drop reference to long dead mailing list. * 104-quad - Remove left over deprecated IIO counter ABI. * adi,adi-axi-adc - Fix wrong bit of docs. * adi,ad5791 - Typos * adi,ad9834 - Switch to device managed functions in probe. * adi,adis* - Add and use helpers for locking to reduced duplication. * adi,adis16480 - Fix calculation of sampling frequency when using pulse per second input. * adi,adis16475 - Calculate the IMU scaled internal sampling rate and runtime depending on sysfs based configuration rather than getting from DT. Drop now unnecessary property from DT bindings doc. * cros_ec - Fix result of a series of recent changes that means extended buffer attributes turn up in the wrong place. Too complex to revert the various patches unfortunately so this is a bit messy. * fsl,mma3452 - Indentation cleanup. * hid-sensors - Size of storage needs to increase for some parts when using quaternions. - Move the get sensistivity attribute to hid-sensors-common to reduce duplication. Enable it for more device types. - Correctly handle relative sensitivity if reported that way including documenting the new ABI. * maxim,max517 - Use device managed functions in probe. * mediatek,mt6360-adc - Use asm/unaligned.h instead of directly including unaligned/be_byteshift.h * novuton,npcm-adc - Local lock instead of missusing mlock. * semtech,sx9500 - Typos * st,sensor - typo fix * st,spear-adc - Local lock instead of missusing mlock. * st,stm32-adc - Long standing HAS_IOMEM dependency fix. * st,stm32-counter - Remove left over deprecated IIO counter ABI. * ti,palmas-adc - Local lock instead of missusing mlock. * ti,tmp007 - Switch to device managed functions in probe.

Commit 2e2366c2d141 ("iio: cros_ec: unify hw fifo attributes into the core file") should be reverted as it set buffer extended attributes at the wrong place. However, to revert it will requires to revert more commits: commit 165aea80e2e2 ("iio: cros_ec: use devm_iio_triggered_buffer_setup_ext()") commit 21232b4456ba ("iio: buffer: remove iio_buffer_set_attrs() helper")). and we would still have conflict with more recent development. commit ee708e6baacd ("iio: buffer: introduce support for attaching more IIO buffers") Instead, this commit reverts the first 2 commits without re-adding iio_buffer_set_attrs() and set the buffer extended attributes at the right place: 1. Instead of adding has_fw_fifo, deduct it from the configuration: - EC must support FIFO (EC_FEATURE_MOTION_SENSE_FIFO) set. - sensors send data a regular interval (accelerometer, gyro, magnetomer, barometer, light sensor). - "Legacy accelerometer" is only present on EC without FIFO, so we don't need to set buffer attributes. 2. devm_iio_triggered_buffer_setup_ext() does not need to be called when EC does not support FIFO, as there is no FIFO to manage. 3. Use devm_iio_triggered_buffer_setup_ext() when EC has a FIFO to specify the buffer extended attributes.
