2021-11-17iio: st-sensors: Use dev_to_iio_dev() in sysfs callbacksLars-Peter Clausen
Using `dev_get_drvdata()` in IIO sysfs callbacks to get a pointer to the IIO device is a relic from the very early days of IIO. The IIO core as well as most other drivers have switched over to using `dev_to_iio_dev()` instead. This driver is one of the last few drivers remaining that uses the outdated idiom, update it. This will allow to eventually update the IIO core to no longer set the drvdata for the IIO device and free it up for driver usage.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: First set of IIO new device and feature support for the 5.16 cycle Counter subsystem changes now sent separately. This has been a busy cycle, so lots here and a few more stragglers to come next week. Big new feature in this cycle is probably output buffer support. This has been in the works for a very long time so it's great to see Mihail pick up the challenge and build upon his predecessors work to finally bring this feature to mainline. New device support ------------------ * adi,adxl313 - New driver and dt bindings for this low power accelerometer. * adi,adxl355 - New driver and dt bindings for this accelerometer. - Later series adds buffer support. * asahi-kasei,ak8975 - Minor additions to driver to support ak09916 * aspeed,aspeed-adc - Substantial rework plus feature additions to add support for the ast2600 including a new dt bindings doc. * atmel,at91_sama5d2 - Rework and support introduced for the sama7g5 parts. * maxim,max31865 - New driver and bindings for this RTD temperature sensor chip. * nxp,imx8qxp - New driver and bindings for the ADC found on the i.MX 8QuadXPlus Soc. * senseair,sunrise - New driver and bindings for this family of carbon dioxide gas sensors. * sensiron,scd4x - New driver and bindings for this carbon dioxide gas sensor. New features ------------ * Output buffer support. Works in a similar fashion to input buffers, but in this case userspace pushes data into the kfifo which is then drained to the device when a trigger occurs. Support added to the ad5766 DAC driver. * Core, devm_iio_map_array_register() to avoid need for devm_add_action_or_reset() based cleanup in fully managed allocation drivers. * Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a few drivers where it really hard to ensure the correct data alignment in an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce buffer so should be avoided whenever possible. Used in the ti,adc108s102, invense,mpu3050 and adi,adis16400. This closes the last known set of drivers with alignment issues at this interface. * maxim,max1027 - Substantial rework to this driver main target of which was supporting use of other triggers than it's own EOC interrupt. - Transfer optimization. * nxp,fxls8962af - Threshold even support including using it as a wakeup source. Cleanups, minor fixes etc ------------------------- Chances of a common type to multiple drivers: * devm_ conversion and drop of .remove() callbacks in: - adi,ad5064 - adi,ad7291 - adi,ad7303 - adi,ad7746 - adi,ad9832 - adi,adis16080 - dialog,da9150-gpadc - intel,mrfld_adc - marvell,berlin2 - maxim,max1363 - maxim,max44000 - nuvoton,nau7802 - st_sensors (includes a lot of rework!) - ti,ads8344 - ti,lp8788 * devm_platform_ioremap_resource() used to reduce boilerplate - cirrus,ep93xx - rockchip,saradc - stm,stm32-dac * Use dev_err_probe() in more places to both not print on deferred probe and ensure a reason for the deferral is available for debug purposes. - adi,ad8801 - capella,cm36651 - linear,ltc1660 - maxim,ds4424 - maxim,max5821 - microchip,mcp4922 - nxp,lpc18xx - onnn,noa1305 - st,lsm9ds0 - st,st_sensors - st,stm32-dac - ti,afe4403 - ti,afe4404 - ti,dac7311 * Drop error returns in SPI and I2C remove() functions as they are ignored and long term plan is to change these all over to returning void. In some cases these patches just make it 'obvious' they always return 0 where it was the case before but not easy to tell. - adi,ad5380 - adi,ad5446 - adi,ad5686 - adi,ad5592r - bosch,bma400 - bosch,bmc150 - fsl,mma7455 - honeywell,hmc5843 - kionix,kxsd9 - maxim,max5487 - meas,ms5611 - ti,afe4403 Driver specific changes * adi,ad5770r - Bring driver inline with documented bindings. * adi,ad7746 - Trivial style fix * adi,ad7949 - Express some magic values as the underlying parts via new #defines. - Make it work with SPI controllers that don't support 14 or 16 bit messages - Support selection of voltage reference from dt including expanding the dt-bindings to cover this new functionality. * adi,ad799x - Implement selection of external reference voltage on AD7991, AD7995 and AD7999. - Add missing dt-bindings doc for devices supported by this driver. * adi,adislib - Move interrupt startup to better location in startup flow. - Handle devices that cannot mask/unmask the drdy pin and must instead mask at the interrupt controller. Applies to the adis16460 and adis16475 from which we then drop equivalent code. * adi,ltc2983 - Add support for optional reset pin. - Fail to probe if no channels specified in dt binding. * asahi-kasei,ak8975 - dt-binding additions of missing vid-supply regulator. * aspeed,aspeed-adc - Typo fix. * fsl,mma7660 - Mark acpi_device_id table __maybe_unused to avoid build warning. * fsl,imx25-gcq - Avoid initializing regulators that aren't used. * invensense,mpu3050 - Drop a dead protection against a clash with the old input driver. * invensense,mpu6050 - Rework code to not use strcpy() and hence avoid possibility of wrong sized buffers.

2021-10-19iio: triggered-buffer: extend support to configure output buffersAlexandru Ardelean
Now that output (kfifo) buffers are supported, we need to extend the {devm_}iio_triggered_buffer_setup_ext() parameter list to take a direction parameter. This allows us to attach an output triggered buffer to a DAC device. Unfortunately it's a bit difficult to add another macro to avoid changing 5 drivers where {devm_}iio_triggered_buffer_setup_ext() is used. Well, it's doable, but may not be worth the trouble vs just updating all these 5 drivers.

2021-09-14iio: st_sensors: remove reference to parent device object on st_sensor_dataAlexandru Ardelean
The idea behind it, is that all devm_ calls in ST sensors are bound to the parent device object. However, the reference to that object is kept on both the st_sensor_data struct and the IIO object parent (indio_dev->dev.parent). This change only adds a bit consistency and uses the reference stored on indio_dev->dev.parent, to enforce the assumption that all ST sensors' devm_ calls are bound to the same reference as the one store on st_sensor_data.

This change converts the st_sensors_power_enable() function to use devm_add_action_or_reset() handlers to register regulator_disable hooks for when the drivers get unloaded. The parent device of the IIO device object is used. This is based on the assumption that all other devm_ calls in the ST sensors use this reference. This makes the st_sensors_power_disable() un-needed. Removing this also changes unload order a bit, as all ST drivers would call st_sensors_power_disable() first and iio_device_unregister() after that.

2021-05-10iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERAlexandru Ardelean
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.

2021-03-25iio: cros: unify hw fifo attributes without API changesGwendal Grignou
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. Fixes: 2e2366c2d141 ("iio: cros_ec: unify hw fifo attributes into the core file") Fixes: 165aea80e2e2 ("iio: cros_ec: use devm_iio_triggered_buffer_setup_ext()") Signed-off-by: Gwendal Grignou <gwendal@chromium.org> Reviewed-by: Alexandru Ardelean <ardeleanalex@gmail.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Link: https://lore.kernel.org/r/20210318184857.2679181-1-gwendal@chromium.org Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2021-03-11iio: make use of devm_iio_kfifo_buffer_setup() helperAlexandru Ardelean
All drivers that already call devm_iio_kfifo_allocate() & iio_device_attach_buffer() are simple to convert to iio_device_attach_kfifo_buffer() in a single go. This change does that; the unwind order is preserved. What is important, is that the devm_iio_kfifo_buffer_setup() be called after the indio_dev->modes is assigned, to make sure that INDIO_BUFFER_SOFTWARE flag is set and not overridden by the assignment to indio_dev->modes. Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of 'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().

Accessing 'indio_dev->buffer' directly (as is done with 'iio_buffer_set_attrs(indio_dev->buffer, <attrs>)'). 2. The way that the buffer attributes would get handled or expanded when there are more buffers per IIO device. Current a sysfs kobj_type expands into a 'device' object that expands into an 'iio_dev' object. We will need to change this, so that the sysfs attributes for IIO buffers expand into IIO buffers at some point. Right now, the current IIO framework works fine for the '1 IIO device == 1 IIO buffer' case (that is now).

Use PLATFORM_DEVID_NONE define instead of "-1" value because: - it brings some meaning, - it might point attention why auto device ID was not used.

2020-08-24iio: cros_ec: Accept -EOPNOTSUPP as 'not supported' error codeGuenter Roeck
A follow-up patch will extend the number of errors reported by cros_ec_cmd_xfer_status(). Specifically, the function will return -EOPNOTSUPP if a command is not supported by the EC. Prepare for it.

BMI160 Minimium gyroscope frequency in normal mode is 25Hz. When older EC firmware do not report their sensors frequencies, use 25Hz as the minimum for gyroscope to be sure it works on BMI160.
