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.

By flushing the output, iio_event_monitor can be more useful to programs
chained along with it.
iio_event_monitor stk3310 | awk '/rising/{system("my_unlockscreen.sh")} /falling/{system("my_lockscreen.sh")}'
Without this flush, the above example would buffer a number of events,
then after a while run the lock/unlock scripts several times.

An overflow (OVF packet) is treated as an error because it represents a
loss of trace data, but there is no loss of synchronization, so the packet
state should be INTEL_PT_STATE_IN_SYNC not INTEL_PT_STATE_ERR_RESYNC.
To support that, some additional variables must be reset, and the FUP
packet that may follow OVF is treated as an FUP event.

AMD proceessors define an address range that is reserved by HyperTransport
and causes a failure if used for guest physical addresses. Avoid
selftests failures by reserving those guest physical addresses; the
rules are:
- On parts with <40 bits, its fully hidden from software.
- Before Fam17h, it was always 12G just below 1T, even if there was more
RAM above this location. In this case we just not use any RAM above 1T.
- On Fam17h and later, it is variable based on SME, and is either just
below 2^48 (no encryption) or 2^43 (encryption).
