git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI updates from Rafael Wysocki: "These rework the handling of ACPI device objects to use the driver core facilities for managing child ones instead of some questionable home-grown ways without the requisite locking and reference counting, clean up the EC driver, improve suspend-to-idle handling on x86, add some systems to the ACPI backlight quirk list, fix some assorted issues, clean up code and improve documentation. Specifics: - Use facilities provided by the driver core and some additional helpers to handle the children of a given ACPI device object in multiple places instead of using the children and node list heads in struct acpi_device which is error prone (Rafael Wysocki). - Fix ACPI-related device reference counting issue in the hisi_lpc bus driver (Yang Yingliang). - Drop the children and node list heads that are not needed any more from struct acpi_device (Rafael Wysocki). - Drop driver member from struct acpi_device (Uwe Kleine-König). - Drop redundant check from acpi_device_remove() (Uwe Kleine-König). - Prepare the CPPC library for handling backwards-compatible future _CPC return package formats gracefully (Rafael Wysocki). - Clean up the ACPI EC driver after previous changes in it (Hans de Goede). - Drop leftover acpi_processor_get_limit_info() declaration (Riwen Lu). - Split out thermal initialization from ACPI PSS (Riwen Lu). - Annotate more functions in the ACPI CPU idle driver to live in the cpuidle section (Guilherme G. Piccoli). - Fix _EINJ vs "special purpose" EFI memory regions (Dan Williams). - Implement a better fix to avoid spamming the console with old error logs (Tony Luck). - Fix typo in a comment in the APEI code (Xiang wangx). - Save NVS memory during transitions into S3 on Lenovo G40-45 (Manyi Li). - Add support for upcoming AMD uPEP device ID AMDI008 to the ACPI suspend-to-idle driver for x86 platforms (Shyam Sundar S K). - Clean up checks related to the ACPI_FADT_LOW_POWER_S0 platform flag in the LPIT table driver and the suspend-to-idle driver for x86 platforms (Rafael Wysocki). - Print information messages regarding declared LPS0 idle support in the platform firmware (Rafael Wysocki). - Fix missing check in register_device_clock() in the ACPI driver for Intel SoCs (huhai). - Fix ACS setup in the VIOT table parser (Eric Auger). - Skip IRQ override on AMD Zen platforms where it's harmful (Chuanhong Guo). - Use native backlight on Dell Inspiron N4010 (Hans de Goede). - Use native backlight on some TongFang devices (Werner Sembach). - Drop X86 dependency from the ACPI backlight driver Kconfig (Riwen Lu). - Shorten the quirk list in the ACPI backlight driver by identifying Clevo by board_name only (Werner Sembach). - Remove useless NULL pointer checks from 2 ACPI PCI link management functions (Andrey Strachuk). - Fix obsolete example in the ACPI EINJ documentation (Qifu Zhang). - Update links and references to _DSD-related documents (Sudeep Holla)" * tag 'acpi-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (46 commits) ACPI/PCI: Remove useless NULL pointer checks ACPI: CPPC: Do not prevent CPPC from working in the future ACPI: PM: x86: Print messages regarding LPS0 idle support ACPI: resource: skip IRQ override on AMD Zen platforms Documentation: ACPI: EINJ: Fix obsolete example ACPI: video: Use native backlight on Dell Inspiron N4010 ACPI: PM: s2idle: Use LPS0 idle if ACPI_FADT_LOW_POWER_S0 is unset Revert "ACPI / PM: LPIT: Register sysfs attributes based on FADT" ACPI: video: Shortening quirk list by identifying Clevo by board_name only ACPI: video: Force backlight native for some TongFang devices ACPI: PM: s2idle: Add support for upcoming AMD uPEP HID AMDI008 ACPI: VIOT: Fix ACS setup ACPI: bus: Drop unused list heads from struct acpi_device hisi_lpc: Use acpi_dev_for_each_child() bus: hisi_lpc: fix missing platform_device_put() in hisi_lpc_acpi_probe() ACPI: bus: Drop driver member of struct acpi_device ACPI: bus: Drop redundant check in acpi_device_remove() ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP ACPI: LPSS: Fix missing check in register_device_clock() ACPI: APEI: Better fix to avoid spamming the console with old error logs ...

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 ...

2022-06-27mfd: core: Use acpi_dev_for_each_child()Rafael J. Wysocki1-7/+24
Instead of walking the list of children of an ACPI device directly, use acpi_dev_for_each_child() to carry out an action for all of the given ACPI device's children. This will help to eliminate the children list head from struct acpi_device as it is redundant and it is used in questionable ways in some places (in particular, locking is needed for walking the list pointed to it safely, but it is often missing).

2022-06-18mfd: qcom-spmi-pmic: expose the PMIC revid information to clientsCaleb Connolly1-90/+175
Some PMIC functions such as the RRADC need to be aware of the PMIC chip revision information to implement errata or otherwise adjust behaviour, export the PMIC information to enable this. This is specifically required to enable the RRADC to adjust coefficients based on which chip fab the PMIC was produced in, this can vary per unique device and therefore has to be read at runtime.

cros_ec_command() is the name of a function as well as a struct, as such it can confuse indexing tools (like ctags). Avoid this by renaming it to cros_ec_cmd(). Update all the callsites to use the new name. This patch is a find-and-replace, so should not introduce any functional changes.

2022-05-23mfd: rt4831: Improve error reporting for problems during .remove()Uwe Kleine-König1-1/+6
Returning an error value in an i2c remove callback results in a generic error message being emitted by the i2c core, but otherwise it doesn't make a difference. The device goes away anyhow and the devm cleanups are called. So instead of triggering the generic i2c error message, emit a more helpful message if a problem occurs and return 0 to suppress the generic message. This patch is a preparation for making i2c remove callbacks return void.
