| * iio: proximity: srf04: Use pm_ptr() to remove unused struct dev_pm_opsJonathan Cameron2022-09-211-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CONFIG_PM is not set, the pm_ptr() will ensure that the struct dev_pm_ops and callbacks are removed without the need for __maybe_unused markings. In this case we can't simply use DEFINE_RUNTIME_DEV_PM_OPS() because that would provide suspend and resume functions without the checks the driver is doing before calling runtime_pm functions (whether the necessary GPIO is provided). It may be possible to clean that up in future by moving the checks into the callbacks.

* | i2c: Make remove callback return voidUwe Kleine-König2022-08-162-6/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

One immutable branch in here due to MFD and SPMI elements needed for the qcom-rradc driver. Device support * bmi088 - Add support for bmi085 (accelerometer part of IMU) - Add support for bmi090l (accelerometer part of IMU) * mcp4922 - Add support for single channel device MCP4921 * rzg2l-adc - Add compatible and minor tweaks to support RZ/G2UL ADC * sca3300 - Add support for scl3300 including refactoring driver to support multiple device types and cleanup noticed whilst working on driver. * spmi-rradc - New driver for Qualcomm SPMI Round Robin ADC including necessary additional utility functions in SPMI core and related MFD driver. * ti-dac55781 - Add compatible for DAC121C081 which is very similar to existing parts. Features * core - Warn on iio_trigger_get() on an unregistered IIO trigger. * bma400 - Triggered buffer support - Activity and step counting - Misc driver improvements such as devm and header ordering * cm32181 - Add PM support. * cros_ec - Sensor location support * sx9324 - Add precharge resistor setting - Add internal compensation resistor setting - Add CS idle/sleep mode. * sx9360 - Add precharge resistor setting * vl53l0x - Handle reset GPIO, regulator and relax handling of irq type. Cleanup and minor fixes: Treewide changes - Cleanup of error handling in remove functions in many drivers. - Update dt-binding maintainers for a number of ADI bindings. - Several sets of conversion of drivers from device tree specific to generic device properties. Includes fixing up various related header and Kconfig issues. - Drop include of of.h from iio.h and fix up drivers that need to include it directly. - More moves of clusters of drivers into appropriate IIO_XXX namespaces. - Tree wide fix of a long running bug around DMA safety requirements. IIO was using __cacheline_aligned to pad iio_priv() structures. This worked for a long time by coincidence, but correct alignment is ARCH_KMALLOC_MINALIGN. As there is activity around this area, introduce an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather than every driver in future. Note, there have been no reports of this bug in the wild, and it may not happen on any platforms supported by upstream, so no rush to backport these fixes. Other cleanup * core - Switch to ida_alloc()/free() - Drop unused iio_get_time_res() - Octal permissions and DEVICE_ATTR_* macros. - Cleanup bared unsigned usage. * MAINTAINERS - Add include/dt-bindings/iio/ to the main IIO entry. * ad5380 - Comment syntax fix. * ad74413r - Call to for_each_set_bit_from(), with from value as 0 replaced. * ad7768-1 - Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core. * adxl345 - Fix wrong address in dt-binding example. * adxl367 - Drop extra update of FIFO watermark. * at91-sama5d2 - Limit requested watermark to the hwfifo size. * bmg160, bme680 - Typos * cio-dac - Switch to iomap rather than direct use of ioports * kxsd9 - Replace CONFIG_PM guards with new PM macros that let the compiler cleanly remove the unused code and structures when !CONFIG_PM * lsm6dsx - Use new pm_sleep_ptr() and EXPORT_SIMPLE_DEV_PM_OPS(). Then move to Namespace. * meson_saradc - general cleanup. - Avoid attaching resources to iio_dev->dev - Use same struct device for all error messages - Convert to dev_err_probe() and use local struct device *dev to reduce code complexity. - Use devm_clk_get_optional() instead of hand rolling. - Use regmap_read_poll_timeout() instead of hand rolling. * mma7660 - Drop ACPI_PTR() use that is unhelpful. * mpu3050 - Stop exporting symbols not used outside of module - Switch to new DEFINE_RUNTIME_DEV_PM_OPS() macro and move to Namespace. * ping - Typo fix * qcom-spmi-rradc - Typo fix * sc27xx - Convert to generic struct u32_fract * srf08 - Drop a redundant check on !val * st_lsm6dsx - Limit the requested watermark to the hwfifo size. * stm32-adc - Use generic_handle_domain_irq() instead of opencoding. - Fix handling of ADC disable. * stm32-dac - Use str_enabled_disable() instead of open coding. * stx104 - Switch to iomap rather than direct use of ioports * tsc2046 - Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core. * tsl2563 - Replace flush_scheduled_work() with cancel_delayed_work_sync() - Replace cancel_delayed_work() with cancel_delayed_work_sync() * vl53l0x - Make the VDD regulator optional by allowing a dummy regulator. * tag 'iio-for-5.20a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (244 commits) iio: adc: xilinx-xadc: Drop duplicate NULL check in xadc_parse_dt() iio: adc: xilinx-xadc: Make use of device properties iio: light: cm32181: Add PM support iio: adc: ad778-1: do not explicity set INDIO_BUFFER_TRIGGERED mode iio: adc: ti-tsc2046: do not explicity set INDIO_BUFFER_TRIGGERED mode iio: adc: stm32-adc: disable adc before calibration iio: adc: stm32-adc: make safe adc disable iio: dac: ad5380: align '*' each line and drop unneeded blank line iio: adc: qcom-spmi-rradc: Fix spelling mistake "coherrency" -> "coherency" iio: Don't use bare "unsigned" dt-bindings: iio: dac: mcp4922: expand for mcp4921 support iio: dac: mcp4922: add support to mcp4921 iio: chemical: sps30: Move symbol exports into IIO_SPS30 namespace iio: pressure: bmp280: Move symbol exports to IIO_BMP280 namespace iio: imu: bmi160: Move exported symbols to IIO_BMI160 namespace iio: adc: stm32-adc: Use generic_handle_domain_irq() proximity: vl53l0x: Make VDD regulator actually optional MAINTAINERS: add include/dt-bindings/iio to IIO SUBSYSTEM AND DRIVERS dt-bindings: iio/accel: Fix adi,adxl345/6 example I2C address iio: gyro: bmg160: Fix typo in comment ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are four possible gain values according to 'sx9324_gain_vals[]': 1, 2, 4, and 8 The values are off by one when writing and reading the register. The bits should be set according to this equation: ilog2(<gain>) + 1 so that a gain of 8 is 0x4 in the register field and a gain of 4 is 0x3 in the register field, etc. Note that a gain of 0 is reserved per the datasheet. The default gain (SX9324_REG_PROX_CTRL0_GAIN_1) is also wrong. It should be 0x1 << 3, i.e. 0x8, not 0x80 which is setting the reserved bit 7.

* | iio:proximity:sx_common: Fix device property parsing on DT systemsStephen Boyd2022-04-041-0/+1
|/ | | | | | | | | | | | | | | | | | | After commit 7a3605bef878 ("iio: sx9310: Support ACPI property") we started using the 'indio_dev->dev' to extract device properties for various register settings in sx9310_get_default_reg(). This broke DT based systems because dev_fwnode() used in the device_property*() APIs can't find an 'of_node'. That's because the 'indio_dev->dev.of_node' pointer isn't set until iio_device_register() is called. Set the pointer earlier, next to where the ACPI companion is set, so that the device property APIs work on DT systems.
