Merge tag 'iio-for-5.17a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: 1st set of IIO new device support, features and cleanup for 5.17 Includes some fixes that were either late breaking, low priority or complex enough to not be good to rush in late in the cycle. Tree rebased today to fix up some trivial issues + pull in a fix that was previously on the fixes-togreg branch. Vast majority have been in linux-next for some time now. New device support * adi,ad7293 - New driver and bindings for this Power Amplifier drain current controller. A complex device with various related monitoring functions. * adi,ad75513R - New driver and bindings for this combined ADC and DAC device. - A few follow up fixes. * adi,admv8818 - New driver (and type) for this 2-18GHz filter device. Includes bindings and ABI documentation to allow clk_notifier based auto adjustment of the filters in appropriate applications. * liteon,ltr501 - Support for the ltr303. ID and chip specific info table. * xilinx,ams - New generic firmware function fwnode_iomap() as used in this driver. - New driver and bindings for this ADC and on-chip sensors as found in various Xilinx devices. Core * Introduced IIO_VAL_INT_64 which uses val and val2 in IIO callbacks to form a 64 bit integer when higher precision needed. * Allow IIO_ENUM_AVAILABLE to be used with different shared values. * Fix a long term issue with scheduling whilst atomic when iio_trig_poll() is called but no trigger consumers are actually enabled and hence the trigger may be reenabled from the interrupt handler. Seen in the wild on the tsc2046. * Mark iio_device_type const. * buffer: Use a separate index variable to simplify code. * buffer-dma: Clear out unused struct iio_buffer_block * buffer-dmaengine: Switch to cheaper round_down() as power of 2 values. Tests/tools * format_value - Check against NULL returns from allocations in tests. - Add IIO_VAL_INT_64 test case. * event_monitor - Flush the output after event to given more consistent latency when tool output piped to other programs. Driver Features * axp20x - Add support for NTC thermistor channel and document TS pin binding. * arm,scmi - Add reading of raw channel values (using IIO_VAL_INT_64) * liteon,ltr501 - Add proximity-near-level support and dt-binding. Tree wide cleanup * Remove no-op trigger ops from multiple drivers. * Stop using dev_get_drvdata() on the iio_dev->dev in various drivers and then stop assigning it to allow this to be used for other purposes. We can always get to the indio_dev using dev_to_iio_dev() which is a container_of() based approach. Also cleanup up some related unnecessary convoluted cases. - atmel,at91-sam5d2 - nxp,imx7d - meas,ms5611 - st,st_sensors * Where available (or easy to introduce) use the scan_type.* values in place of a second copy for read_raw and similar paths. - adi,ad7266 - bosch,bma220 - fsl,mac3110 - fsl,mma7455 - fsl,mpl3115 - kionix,kcjk-1013 - sensortek,stk8ba50 - sensortek,stk8312 - ti,adc12138 - ti,ads1015 - vti,sca3000 - xilinx,xadc-core * Switch drives over to generic firmware properties including appropriate header changes to avoid including of.h - Various DACs had false CONFIG_OF dependencies. - dpot-dac - envelope-detector - adi,ad5755 - adi,ad5758 - capella,cm3605 - maxim,max9611 - microchip,mcp41010 - microchip,mcp3911 - ti,adc12138 * Trivial clang warning fixes for W=1 warnings. Driver specific cleanup and minor fixes * adi,ad7606 - Comment fixes. * ams,ad3935 - Drop pointless cast to the same type. * atmel,at91-sama5d2 - Fix wrong cast of iio_dev->dev to platform_device that happened to be harmless. * fsl,mma7660 - Stop i2c remove() function returning an error code. Part of a rework to eventually stop returning anything from these. * fsl,mma8452 - Use correct type for local irqreturn_t. * nxp,imx8mq - Maintainer email address update. * nxp,lpc18xx_adc - Ensure clk_prepare_enable() called before clk_get_rate(). - Switch of.h for mod_devicetable.h to reflect no of specific functions, just the id table. * renesas,rzg2l - Drop a dev_err() that just duplicates error printed in platform_get_irq() * sgx,vz89x - Drop pointless cast. * st,lsm6dsx - Make it possible to disable the sensorhub from DT to avoid a corner case where the address of a slave device many be accidentally modified. * st,stm32-adc - Stop leaking an of_node in an error path. * st,stmp2 - Avoid wrong sized type for bit field which could result in over-reading (harmless). Precursor to enabling -Warray-bounds. * ti,adc081c - Put back some ACPI support for non standards compliant ADC081C ID because it is known to be in the wild on some Aaeon boards. * ti,ads8688 - Cleanup redundant local ret variable assignment. * ti,ina2xx-adc - Use helper macro kthread_run() to replace some boilerplate. - Avoid double reference counting. - Drop pointless cast. * xilinx,xadc - Make the IRQ optional as not always wired to the host system. * tag 'iio-for-5.17a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (103 commits) iio: adc: ti-adc081c: Partial revert of removal of ACPI IDs iio:addac:ad74413r: Fix uninitialized ret in a path that won't be hit.

Unfortuanately a non standards compliant ACPI ID is known to be in the wild on some AAEON boards. Partly revert the removal of these IDs so that ADC081C will again work + add a comment to that affect for future reference. Whilst here use generic firmware properties rather than the ACPI specific handling previously found in this driver. Reported-by:

I don't believe it's possible to hit this, because we drop out of __iio_update_buffers() earlier in the event of an empty list. However, that is not visible to the compiler so lets return an error if we do hit the loop with an empty bitmask.

The AMS includes an ADC as well as on-chip sensors that can be used to sample external voltages and monitor on-die operating conditions, such as temperature and supply voltage levels. The AMS has two SYSMON blocks. PL-SYSMON block is capable of monitoring off chip voltage and temperature. PL-SYSMON block has DRP, JTAG and I2C interface to enable monitoring from an external master. Out of these interfaces currently only DRP is supported. Other block PS-SYSMON is memory mapped to PS. The AMS can use internal channels to monitor voltage and temperature as well as one primary and up to 16 auxiliary channels for measuring external voltages. The voltage and temperature monitoring channels also have event capability which allows to generate an interrupt when their value falls below or raises above a set threshold. Co-developed-by:

This patch introduces a new helper routine - fwnode_iomap(), which allows to map the memory mapped IO for a given device node. This implementation does not cover the ACPI case and may be expanded in the future. The main purpose here is to be able to develop resource provider agnostic drivers. Suggested-by:

A bug exists if the user executes a COUNTER_ADD_WATCH_IOCTL ioctl call, and then executes a COUNTER_DISABLE_EVENTS_IOCTL ioctl call. Disabling the events should disable the 104-QUAD-8 interrupts, but because of this bug the interrupts are not disabling. The reason this bug is occurring is because quad8_events_configure() is called when COUNTER_DISABLE_EVENTS_IOCTL is handled, but the next_irq_trigger[] array has not been cleared before it is checked in the loop. This patch fixes the bug by removing the next_irq_trigger array and instead utilizing a different algorithm of walking the events_list list for the current requested events. When a COUNTER_DISABLE_EVENTS_IOCTL is handled, events_list will be empty and thus all device channels end up with interrupts disabled.

An initialised kobject must be freed using kobject_put() to avoid leaking associated resources (e.g. the object name). Commit fe3c6068 ("firmware: Fix a reference count leak.") "fixed" the leak in the first error path of the file registration helper but left the second one unchanged. This "fix" would however result in a NULL pointer dereference due to the release function also removing the never added entry from the fw_cfg_entry_cache list. This has now been addressed. Fix the remaining kobject leak by restoring the common error path and adding the missing kobject_put().

Commit fe3c6068 ("firmware: Fix a reference count leak.") "fixed" a kobject leak in the file registration helper by properly calling kobject_put() for the entry in case registration of the object fails (e.g. due to a name collision). This would however result in a NULL pointer dereference when the release function tries to remove the never added entry from the fw_cfg_entry_cache list. Fix this by moving the list-removal out of the release function. Note that the offending commit was one of the benign looking umn.edu fixes which was reviewed but not reverted.
