iio: adc: add max11205 adc driver
Adding support for max11205 16-bit single-channel ultra-low power delta-sigma adc. The MAX11205 is compatible with the 2-wire interface and uses SCLK and RDY/DOUT for serial communications. In this mode, all controls are implemented by timing the high or low phase of the SCLK. The 2-wire serial interface only allows for data to be read out through the RDY/DOUT output.

iio:adc:ad7280a: Move out of staging
This is a rather unusual device (in IIO anyway). However, it has a near to standard userspace ABI. Note the work to move this out of staging was done against a minimal QEMU model, which doesn't model all the features of the device. I have no intention to upstream the QEMU model as it was developed just to enable this driver cleanup. https://github.com/jic23/qemu/tree/ad7280a-hacks Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Marcelo Schmitt <marcelo.schmitt1@gmail.com> Link: https://lore.kernel.org/r/20220206190328.333093-21-jic23@kernel.org |

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

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.

- nxp,imx7d
- meas,ms5611
- st,st_sensors

iio: adc: Add Xilinx AMS driver
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.

iio: imx8qxp-adc: fix dependency to the intended ARCH_MXC config
Commit 1e23dcaa1a9f ("iio: imx8qxp-adc: Add driver support for NXP IMX8QXP
ADC") adds the config IMX8QXP_ADC for this new driver, which depends on
the non-existing config ARCH_MXC_ARM64.
Hence, ./scripts/checkkconfigsymbols.py warns:
ARCH_MXC_ARM64
Referencing files: drivers/iio/adc/Kconfig
Probably, the existing config ARCH_MXC is intended to be referred here.
So, repair the dependency to refer to that config.

iio: adc: add ADC driver for the TI TSC2046 controller
Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for the touchscreen use case. By implementing it as an IIO ADC device, we can make use of resistive-adc-touch and iio-hwmon drivers. Polled readings are currently not implemented to keep this patch small, so iio-hwmon will not work out of the box for now. So far, this driver was tested with a custom version of resistive-adc-touch driver, since it needs to be extended to make use of Z1 and Z2 channels. The X/Y are working without additional changes.

iio: adc: Kconfig: make AD9467 depend on ADI_AXI_ADC symbol
Because a dependency on HAS_IOMEM and OF was added for the ADI AXI ADC
driver, this makes the AD9467 driver have some build/dependency issues
when OF is disabled (typically on ACPI archs like x86).
This is because the selection of the AD9467 enforces the ADI_AXI_ADC symbol
which is blocked by the OF (and potentially HAS_IOMEM) being disabled.
To fix this, we make the AD9467 driver depend on the ADI_AXI_ADC symbol.
The AD9467 driver cannot operate on it's own. It requires the ADI AXI ADC
driver to stream data (or some similar IIO interface).
So, the fix here is to make the AD9467 symbol depend on the ADI_AXI_ADC
symbol. At some point this could become it's own subgroup of high-speed
ADCs.

1st set of IIO/counter device support, features and cleanup in the 5.13 cycle
Big set in here from Alexandru Ardelean enabling multiple buffer support.
This includes providing a new directory per buffer that combines
what was previously in buffer/ and scan_elements/. Old interfaces still
in place for compatiblity.
Note immuatable branch for scmi patches to allow for some significant
rework going on in that subsystem. Merge required updating to reflect
some changes in IIO.
Late rebase to fix some wrong fixes tags due to some earlier rebases
made necessary by messing up the immutable branch.
IIO New Device Support
* adi,ad5686
- Add info to support AD5673R and AD5677R
* bosch,bmi088
- New driver supporting this accelerometer + gyroscope
* cros_ec_mkbp
- New driver for this proximity sensor that exposes a 'front'
sensor. Very simple switch like device, but driver allows it
to share interface with more sophisticated proximity sensors.
* iio_scmi
- New driver to support ARM SCMI protocol to expose underlying
accelerometers and gyroscopes via this firmware interface.
* st,st_magn
- Add ID for IISMDC magnetometer.
* ti,ads131e0
- New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs
Counter New Device Support
* IRQ or GPIO based counter
- New driver for a conceptually simple counter that uses interrupts
to perform the count.
Features
* core
- Dual buffer supprt including:
Various helpers to centralize handling of bufferer related elements.
Document existing and new IOCTLs
Register the IIO chrdev only if it can actually be used for anything.
Rework attribute group creation in the core (lots of patches)
Merge buffer/ and scan_elements/ entries into one list + maintain
backwards compatible set.
Introduce the internal logic and IOCTL to allow multiple buffers
+ access to an anon FD per buffer to actually read from it.
Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
Update ABI docs.
A few follow up fixes, unsuprising as this was a huge bit of rework.
- Move common case setting of trig->parent to the core.
- Provide an iio_read_channel_processed_scale() to avoid loss of
precision from iio_read_channel_processed() then applying integer
scale. Use it in ntc_thermistor driver in hwmon.
- Allow drivers to specify labels from elsewhere than DT. Use it for
bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
- Document label usage for proximity and accelerometer sensors.
- Some local variable renames for consistency
tools
- Add -a parameter to iio_event_monitor to allow autoenabling of events.
* acpi_als
- Add trigger support for devices that don't support notification method.
* adi,ad7124
- Allow more than 8 channels. This is a complex little device, but is
capable of supporting up to 16 channels if the share certain
configuration settings.
* hrtimer-trigger
- Support sampling frequency below 1Hz.
* mediatek,mt8195-auxadc
- Add compatible to binding docs (always also includes mt8173)
* st,stm32-adc
- Enable timetamps when not using DMA.
* vishay,vcnl3020
- Sampling frequency control.
Cleanup and minor fixes:
* treewide
- Use some getter and setter functions instead of opencoding.
- Set of fixes for pointless casts in various drivers.
- Avoid wrong kernel-doc marking on comment blocks.
- Fix various other minor kernel-doc issues shown by W=1
* core
- Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
- Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
- Add unit tests for iio_format_value()
* docs
- Fix formatting/typos in iio_configfs.rst and buffers.rst
- Add documentation of index in buffers.rst
- Fix scan element description
- Avoid some issues with HTML generation from ABI docs by moving
duplicated defintions to more generic files.
- Drop reference to long dead mailing list.
* 104-quad
- Remove left over deprecated IIO counter ABI.
* adi,adi-axi-adc
- Fix wrong bit of docs.
* adi,ad5791
- Typos
* adi,ad9834
- Switch to device managed functions in probe.
* adi,adis*
- Add and use helpers for locking to reduced duplication.
* adi,adis16480
- Fix calculation of sampling frequency when using pulse per second input.
* adi,adis16475
- Calculate the IMU scaled internal sampling rate and runtime depending
on sysfs based configuration rather than getting from DT. Drop now
unnecessary property from DT bindings doc.
* cros_ec
- Fix result of a series of recent changes that means extended buffer
attributes turn up in the wrong place. Too complex to revert the
various patches unfortunately so this is a bit messy.
* fsl,mma3452
- Indentation cleanup.
* hid-sensors
- Size of storage needs to increase for some parts when using quaternions.
- Move the get sensistivity attribute to hid-sensors-common to reduce
duplication. Enable it for more device types.
- Correctly handle relative sensitivity if reported that way including
documenting the new ABI.
* maxim,max517
- Use device managed functions in probe.

adds these dependencies to the Kconfig symbol of the driver.
This was also found via the lkp bot, as the

iio: xilinx-xadc: Add basic support for Ultrascale System Monitor
The xilinx-xadc IIO driver currently has support for the XADC in the Xilinx 7 series FPGAs. The system-monitor is the equivalent to the XADC in the Xilinx UltraScale and UltraScale+ FPGAs. The IP designers did a good job at maintaining backwards compatibility and only minor changes are required to add basic support for the system-monitor core. The non backwards compatible changes are: * Register map offset was moved from 0x200 to 0x400 * Only one ADC compared to two in the XADC * 10 bit ADC instead of 12 bit ADC * Two of the channels monitor different supplies Add the necessary logic to accommodate these changes to support the system-monitor in the XADC driver. Note that this patch does not include support for some new features found in the system-monitor like additional alarms, user supply monitoring and secondary system-monitor access. This might be added at a later time.

iio: adc: at91_adc: add Kconfig dep on the OF symbol and remove of_match_ptr()
This tries to solve a warning reported by the lkp bot:
>> drivers/iio/adc/at91_adc.c:1439:34: warning: unused variable
>> 'at91_adc_dt_ids' [-Wunused-const-variable]
static const struct of_device_id at91_adc_dt_ids[] = {
^
1 warning generated.
This warning has appeared after the AT91_ADC driver compilation has been
enabled via the COMPILE_TEST symbol dependency.
The warning is caused by the 'of_match_ptr()' helper which returns NULL if
OF is undefined. This driver should build only for device-tree context, so
a dependency on the OF Kconfig symbol has been added.
Also, the usage of of_match_ptr() helper has been removed since it
shouldn't ever return NULL (because the driver should not be built for the
non-OF context).

Second set of features and cleanups for IIO in 5.10
We have a couple of changes that apply to large sets of drivers, so
I have grouped those to keep this short.
There are a few late breaking fixes in here that can wait for the
merge window.

* ti,adc12138
* ti,ads1015
* ti,ads7950
* ti,twl4030-madc
Features
--------
* adxrs290
- Add triggered buffer support and expose data ready signal as a possible
trigger. Includes updating bindings.
- Add debugfs hooks for register access.
* mlx90632
- Add a clear user interface to override the measured ambient temperature.
* vl53l0x

Cleanups and minor fixes
------------------------
(groups)
Replace mlock with local lock:
* adf4350
* exynos-adc
* fls-imx25-gcq
* stm32-dac
devm use to simplify probe error handling and remove functions.
* adis16201

is trivial and it breaks ACPI PRP0001 based instantiation.
Mostly this series is about removing examples that get copied into new
drivers.

iio:adc:bcm_iproc: Drop of_match_ptr protection and switch to mod_devicetable.h
This driver cannot be instantiated from ACPI due to it's use of syscon_regmap_lookup_by_phandle() but in the interests of clearing this anti pattern out of IIO, let us switch to an explicit check in Kconfig and remove the protections on the of_match_table The switch of header is because we only use of_device_id in here and that is defined in mod_devicetable.h not of.h.

IIO: Ingenic JZ47xx: Add touchscreen mode.
The SADC component in JZ47xx SoCs provides support for touchscreen operations (pen position and pen down pressure) in single-ended and differential modes. The touchscreen component of SADC takes a significant time to stabilize after first receiving the clock and a delay of 50ms has been empirically proven to be a safe value before data sampling can begin. Of the known hardware to use this controller, GCW Zero and Anbernic RG-350 utilize the touchscreen mode by having their joystick(s) attached to the X/Y positive/negative input pins. JZ4770 and later SoCs introduce a low-level command feature. With it, up to 32 commands can be programmed, each one corresponding to a sampling job. It allows to change the low-voltage reference, the high-voltage reference, have them connected to VCC, GND, or one of the X-/X+ or Y-/Y+ pins. This patch introduces support for 6 stream-capable channels: - channel #0 samples X+/GND - channel #1 samples Y+/GND - channel #2 samples X-/GND - channel #3 samples Y-/GND - channel #4 samples X+/X- - channel #5 samples Y+/Y- Being able to sample X-/GND and Y-/GND is useful on some devices, where one joystick is connected to the X+/Y+ pins, and a second joystick is connected to the X-/Y- pins. All the boards which probe this driver have the interrupt provided from Device Tree, with no need to handle a case where the IRQ was not provided.

First set of new IIO device support, features and cleanup for the 5.8 cycle
Usual mix of new drivers, new support in old drivers and lots of minor
cleanup. Yaml conversions also continue to trickle in (plenty more to go!)
New device support
* ad7476
- Add ad7091 support (ID only)
* ad9467
- New driver for this 200/250 MSPS adi-axi-adc and SPI attached ADC.
* adi-axi-adc
- New driver to support ADIs generic AXI ADC IP core, used to provide
high speed interfaces to ADCs (JESD204B/C or parallel interfaces). Usually
paired with a device using a slow configuration interface (spi etc)
Includes DT bindings and some fixes for fpga headers.
* bmg160
- Add support for BMI088 (ID only)
* max1241
- New driver for this ADC.
* st_sensors
- Add support for LIS2HH12 accelerometer
* sx9310
- New driver supporting sx9310 and sx9311 proximity sensors.
Yaml DT binding conversions
* rockchip-saradc (including adding some missing parts)
* stm32-dac
* tsl2563
* vcnl4000
Features
* st_lsm6dsx
- Add LIS3MDL as a possible sensor hub device.
* vcnl4000
- Add new concept of near level (from DT) to provide to userspace which
often needs to have some calibrated concept of 'near'.
Cleanups, minor fixes etc.
* core
- Use snprintf for functions where strings are built and there is
potential for overflow.
- Correct docs to indicate mlock should not be used directly by drivers.
- Fix up accidental dropping of a patch to use bitmap_zalloc.
- Stop allowing enabling of buffers with no channels enabled.
- Drop unused 'stufftoread' from iio_buffer.
- Drop scan_el_attrs form iio_buffer as unused.
- Reorder sanity checks in __iio_device_register to fail earlier.
- Drop all the devm_ runregister / free functions from IIO as they
were never used and encourage poor design.
* dma-buffer
- Tidy up includes.
* dma-engine-buffer
- Provide dev-managed allocator.
- Fix an issue with printing a size_t

iio: adc: ad9467: add support AD9467 ADC
The AD9467 is a 16-bit, monolithic, IF sampling analog-to-digital converter (ADC). It is optimized for high performanceover wide bandwidths and ease of use. The product operates at a 250 MSPS conversion rate and is designed for wireless receivers, instrumentation, and test equipment that require a high dynamic range. The ADC requires 1.8 V and 3.3 V power supplies and a low voltage differential input clock for full performance operation. No external reference or driver components are required for many applications. Data outputs are LVDS compatible (ANSI-644 compatible) and include the means to reduce the overall current needed for short trace distances. Since the chip can operate at such high sample-rates (much higher than classical interfaces), it requires that a DMA controller be used to interface directly to the chip and push data into memory. Typically, the AXI ADC IP core is used to interface with it.

iio: adc: adi-axi-adc: add support for AXI ADC IP core
This change adds support for the Analog Devices Generic AXI ADC IP core. The IP core is used for interfacing with analog-to-digital (ADC) converters that require either a high-speed serial interface (JESD204B/C) or a source synchronous parallel interface (LVDS/CMOS). Usually, some other interface type (i.e SPI) is used as a control interface for the actual ADC, while the IP core (controlled via this driver), will interface to the data-lines of the ADC and handle the streaming of data into memory via DMA. Because of this, the AXI ADC driver needs the other SPI-ADC driver to register with it. The SPI-ADC needs to be register via the SPI framework, while the AXI ADC registers as a platform driver. The two cannot be ordered in a hierarchy as both drivers have their own registers, and trying to organize this [in a hierarchy becomes] problematic when trying to map memory/registers. There are some modes where the AXI ADC can operate as standalone ADC, but those will be implemented at a later point in time.
