It's not correct to use artificial device created by IIO core to retrieve device properties. Even ->get_default_reg() callback takes a simple struct device pointer which suggests it wants to operate on the real device. Correct this by replacing pointer to IIO device by a real device pointer in the caller of ->get_default_reg().

2022-07-16iio: trigger: move trig->owner init to trigger allocate() stageDmitry Rokosov3-35/+41
To provide a new IIO trigger to the IIO core, usually driver executes the following pipeline: allocate()/register()/get(). Before, IIO core assigned trig->owner as a pointer to the module which registered this trigger at the register() stage. But actually the trigger object is owned by the module earlier, on the allocate() stage, when trigger object is successfully allocated for the driver. This patch moves trig->owner initialization from register() stage of trigger initialization pipeline to allocate() stage to eliminate all misunderstandings and time gaps between trigger object creation and owner acquiring.

This patch set is to support bucket in icc-rpm driver, so it implements the similar mechanism in the icc-rpmh driver. It uses interconnect path tag to indicate the bandwidth voting is for which buckets, and there have three kinds of buckets: AWC, WAKE and SLEEP, finally the wake and sleep bucket values are used to set the corresponding clock (active and sleep clocks). So far, we keep the AWC bucket but doesn't really use it. Link: https://lore.kernel.org/r/20220712015929.2789881-1-leo.yan@linaro.org Signed-off-by: Georgi Djakov <djakov@kernel.org>

In this case we require a strong thread affinity to be able to account for lost time on a per vCPU. This part of the driver is the 'frontend' which is reponsible for delivering the periodic 'pet' events, configuring the virtual peripheral and listening for cpu hotplug events. The other part of the driver is an emulated MMIO device which is part of the KVM virtual machine monitor and this part accounts for lost time by looking at the /proc/{}/task/{}/stat entries.

2022-07-14dt-bindings: vcpu_stall_detector: Add qemu,vcpu-stall-detector compatibleSebastian Ene1-0/+51
The VCPU stall detection mechanism allows to configure the expiration duration and the internal counter clock frequency measured in Hz. Add these properties in the schema. While this is a memory mapped virtual device, it is expected to be loaded when the DT contains the compatible: "qemu,vcpu-stall-detector" node. In a protected VM we trust the generated DT nodes and we don't rely on the host to present the hardware peripherals.

2022-07-14eeprom: idt_89hpesx: uninitialized data in idt_dbgfs_csr_write()Dan Carpenter1-2/+6
The simple_write_to_buffer() function will return positive/success if it is able to write a single byte anywhere within the buffer. However that potentially leaves a lot of the buffer uninitialized. In this code it's better to return 0 if the offset is non-zero. This code is not written to support partial writes. And then return -EFAULT if the buffer is not completely initialized.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO new device support, features and minor fixes for 5.20 Several on-running cleanup efforts dominate this time, plus the DMA safety alignment issue identified due to improved understanding of the restrictions as a result of Catalin Marinas' efforts in that area. 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 ...
