Merge tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc/IIO/etc driver updates from Greg KH: "Here is the big set of char, misc, iio, counter, fpga, and other small driver subsystems for 7.3-rc1.
Overall, due to some driver removals we only added a bit more code than removed, which was a nice change. Highlights in this merge request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used anymore
- Coresight driver updates and additions
- Mei driver udpates
- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported issues
All of these have been in linux-next for a while"

IIO new device support, features, cleanup for 7.3
Includes a merge of 7.2-rc2 to pick up the changes around mod_devicetable.h and reduce resulting conflicts around includes.
New device support ------------------
adi,ad3530R - Add support for the AD3532R and AD3532 16 channel DACs. adi,ad4080 - Add support for the AD4883 ADC. adi,ad5686 - Add support for AD5313R, AD5317R, AD5674, AD5687R, AD5689, AD5689R DACs over SPI - Add support for AD5316R, AD5674, AD5697R and AD5696 DACs over I2C - Significant driver refactoring prior to these additions, partly to reduce bus traffic and to add triggered buffer and gain control support. An earlier set added support for missing supplies, reset and LDAC GPIO. adi,adf41513 - New driver to support this PLL frequency synthesizer that runs up to 26.5 GHz. - Included infrastructure to handle higher precision attributes with extensive tests adi,ltc2378-20 - New driver supporting LTC2338, LTC2364, LTC2367, LTC2368, LT2369, LTC2370 LTC2376, LTC2377, LTC2378, LTC2379 and LTC23980 ADCs with both high speed capture via appropriate backend and conventional triggered buffer SPI capture. invensense,icm42607 - New driver for this IMU. mediateck,mt6323 - New driver for this PMIC ADC. microchip,mcp47a1 - New driver for this I2C 6 bit DAC. nxp,mcf54415-dac - New driver for this DAC found in NXP SoCs. qst,qmc5884l - New driver for this 3 axis magnetometer. Included dt vendor entry for qst. qst,qmc6308 - New driver for this 3 axis magnetometer. sensiron,slf3s - New driver for this liquid flow sensor. Includes adding IIO_VOLUMEFLOW channel type. st,vl53l1x - Refactors to improve readability. ti,ads112c14 - New driver supporting the ADS112C14 and ADS122C14 ADCs. These bring some new ABI for input chopping, particular useful for resistive sensors like thermocouples or Wheatstone bridges. - Support CRC8 detection of corruption on the bus. - Support buffered reads. ti,tmp117 - (trivial) Add support for the tmp119 temperature sensor. xilinx,versal-sysmon - New ADC driver for this block found on various FPGAs including various bus interfaces, threshold and oversampling support.
dt binding updates ------------------ new shared bindings - excitation-channels and excitation-current-nanoamp allow per channel specification of currents used for resistive sensor measurement. - reference-sources property to allow selection of a per channel reference. rockchip,saradc - Add RV1106 which is compatible with the RV3588.
Features --------
buffer-dmaengine - Allow cyclic buffers, useful for repeating sequence generation with DACs. devantech,dmard09 - Implement read back of channel scale - previously interface always returned an error. hid,sensors-als - Enable separate channel scaling for hardware that supports it. invensense,timestamp library - Various precision improvements. invensense,icm42600 - Add support for hwfifo watermark interfaces. taos,tcs3472 - Support wait time and sampling frequency control.
Cleanups, minor fixes ---------------------
Minor cleanups not mentioned at all in this summary such as white space fixes or typos.
Affecting various drivers - Cleanup of conditionals that had no affect. - Drop some runtime pm local wrappers as now runtime_pm does the mark_last_busy part inside the put, these provide no useful code deduplication or readability advantages over directly calling the runtime_pm functions. - Return 0 from write_raw() on success. - Use of dev_err_probe() to simplify code and sometimes provide useful info for deferred probe debugging. - Drop some redundant error prints where the called function already provides information on errors. - Make some read only arrays in functions static. - Fix up missing handling of regcache_sync() errors. - Drop some false kernel-doc markings. - Add missing MODULE_DEVICE_TABLE for some of_match_id tables. - Use local variables for things like the struct device to shorten and improve readability of code. - Drop some unused structure elements. - Reorder dds.h macro parameters to be inline with others. - Header reorders and IWYU. Often part of a more significant series. - Remove abstractions designed to allow a driver to support multiple device types, when they have been around a long time and only the original part showed up. - Initialize spi_device_id arrays using member names following dropping of driver data from drivers that didn't actually use it. - Catch up with i2c_device_id tables added since previous effort to use named initializers for all those. - Use kernel types in a few places instead of standard C ones or bare unsigned.
Misc - Update Xilinx AMS maintainer. - Update email address for Maxwell Doose. - Update email address for Siratul Islam. - Update email address for Tomasz Duszynski and re-add Tomasz to various maintainer entries. Docs - Encourage use of differential channel naming even when there is no flexibility in input to differential pair mapping. Intended to provide a strong signal to userspace that a channel is differential. adi,ad_sigma_delta - Allow COMPILE_TEST without any users. adi,ad2s1201 - Refactor trigger handler to avoid mix of guard() and goto. adi,ad5686 - Avoid potential NULL dereference is user forces a driver bind. adi,ad5696 - Add a couple of missing entries to the of_match_id table and update binding to match. atmel,ad91_adc - Use const char * for DT string property allowing a cast to be dropped. avia,hx711 - Various refactors and cleanup to enable support of additional parts (to come) - Add missing supply and gpio dt-bindings. bosch,bmc150 - Harden against device reporting too large a FIFO sample count. - Use FIELD_PREP() / FIELD_GET() to improve readability. freescale,fxls8962af - Harden against device reporting too large a FIFO sample count. hid-sensors-* - Reorder probe to not expose userspace interfaces until the rest of the setup is done to avoid potentially dropping data. honeywell,abp2030pa - Drop an unreachable return. invensens,icm45600 - Harden against bad value of FIFO sample count from device. - Use i2c_match_data if firmware table sourced match data isn't available. nxp,mpl1115 - Ensure runtime_pm is balanced on error in probe. rohm,bm1390 - Make the driver slightly more likely to recover from transient errors. sensiron,sgp30 - Handle thread creation errors. st,lsm6dsx - Update the enable mask when doing sensor fusion to avoid incorrect fifo data handling. st,stm32-dfsdm - Treat dt flags as booleans. ti,ads1015 - Switch to devm helpers which simplified code and closed a resource leak. ti,opt3001 - Split complicated opt3001_get_processed() logic into irq an no irq helper functions. - Use devm to simplify code. - Use guard() to simplify code. - Reorder probe so final call exposes userspace interfaces. - Various other more minor cleanup taos,tsl2772 - Fix calibscale readback to check right channel type. taos,tsl2583 - Use sysfs_emit() and sysfs_emit_at() to replace open coded equivalents.

This first step is adding a very basic driver that only supports power on/reset and reading the system monitor channels.
ADS112C14_SYS_MON_CHANNEL_SHORT is the last channel rather than being in logical order by address to keep the voltage channels together and in case we find we need to add variants of this channel with different voltage reference later.

iio: adc: versal-sysmon: add I2C driver
Add an I2C transport driver for the Versal SysMon block. The SysMon provides an I2C slave interface that allows an external master to read voltage and temperature measurements through the same register map used by the MMIO path.
The I2C command frame is an 8-byte structure containing a 4-byte data payload, a 2-byte register offset, and a 1-byte instruction field. Read operations send the frame with a read instruction, then receive a 4-byte response containing the register value.
Events are not supported on the I2C path because there is no interrupt line and the I2C regmap backend cannot be called from atomic context.

It can monitor up to 160 voltage channels and 64 temperature satellites distributed across the SoC, with a consistent sample rate of 8 kSPS per channel regardless of how many channels are enabled.
The hardware also provides four aggregate temperature registers that are always present regardless of the device tree configuration: the current max and min across all active satellites, and the peak and trough values recorded since the last hardware reset.
The driver is split into two compilation units: - versal-sysmon-core: Channel parsing, IIO registration, read_raw - versal-sysmon: MMIO platform driver with custom regmap accessors
Voltage results are stored in a 19-bit modified floating-point format and converted to millivolts. Temperature results are stored in Q8.7 signed fixed-point Celsius format and converted to millicelsius.
The MMIO regmap backend uses a custom reg_write accessor that automatically unlocks the NPI (NoC programming interface) lock register before each write, as required by the hardware. The regmap is configured with fast_io since the underlying MMIO accessors are safe to call from atomic context.

iio: adc: ad_sigma_delta: allow COMPILE_TEST in isolation
AD_SIGMA_DELTA is a hidden tristate that can only be enabled by selecting drivers (AD7124, AD7192, etc.), all of which require SPI. This prevents compile-testing the library code directly with allmodconfig or by manually enabling it with COMPILE_TEST.
Add a prompt string guarded by "if COMPILE_TEST" so the symbol becomes directly selectable when COMPILE_TEST is set.
Also add an explicit "depends on SPI" since the ad_sigma_delta library directly calls SPI core symbols such as spi_bus_lock(), spi_bus_unlock(), and spi_sync_locked().
