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.

iio: tsl2772: Use scnprintf() for avoiding potential buffer overflow
snprintf() is a hard-to-use function, it's especially difficult to use
it for concatenating substrings in a buffer with a limited size.
Since snprintf() returns the would-be-output size, not the actual
size, the subsequent use of snprintf() may go beyond the given limit
easily. Although the current code doesn't actually overflow the
buffer, it's an incorrect usage.
This patch replaces such snprintf() calls with a safer version,
scnprintf().
Also this fixes the incorrect argument of the buffer limit size passed
to snprintf(), too. The size has to be decremented for the remaining
length.

This change adds it back. The only difference is that it's adding

set up virtual bridges we are using CONFIG_ADDR Register which is
wrong. Hence, set the correct value.
Fixes: 9a5e71a68d20 ("staging: mt7621-pci: simplify 'mt7621_pcie_init_virtual_bridges' function")

Jonathan writes:
First set of new IIO device support, fatures and cleanups for the 5.7 cycle
Includes changes for the counter subsystem
Core Feature
* Explicitly handle sysfs values in dB, including correctly handling the
needed postfix dB.
* Add a TODO to suggest suitable activities for new contributors to IIO now
the vast majority of drivers are out of staging (and the remaining ones
there are 'hard'). Also update the TODO in staging to remove stale entries.
Staging graduations
* ad7192 ADC.
New device support
* ad5770r
- New driver for this 6 channel DAC including DT bindings.
* ad8366
- Add supprot for the hmc1119 attenuator.
* al3010
- New driver supporting this Dyna-image light sensors.
- Power management and DT bindings added in additional patches.
* atlas-sensor
- Add support for atlas DO-SM device. Reads disolved oxygen in a solution.
* gpap002x00f
- New driver and bindings to support the GP2AP002A00F and GP2AP002S00F light
and proximity sensors. There is some limited existing support in
input. The intent is to drop this driver once IIO driver is in place.
* hmc425a
- New driver for this attenuator.
* icp10100
- New driver for this presure sensor.
* ltc2632
- Add support for the ltc2636 8 channel DAC. Includes bindings and some
tidying up of the driver.
* inv_mpu6050
- Support IAM20680, ICM20609, ICM20689 and ICM20690.
Includes related tidy up and rework of low pass filter bandwidth
handling to give suitable values for all chips.
Binding conversions to yaml or missing bindings docs.
* atlas-sensor, including consolidation of previous 3 separate docs into 1.
* ad7923, previously no doc.
* max1363, split into max1238 and max1363 to simplify yaml.
* stm32-adc
Features
* (counter) 104-quad-8
- Support a filter clock prescaler.
- Support reporting of encoder cable status.
* ad7124
- Low pass filter support.
- Debugfs interface to access registers directly.
* ad8366
- Support control of hardware gain.
* inv_mpu6050
- Runtime pm with autosuspend.
* npcm adc
- Add reset support. This is a breaking change if DT is not in sync,
however this device is a BMC so the ecosystem is closed enought that
this should not be a problem.
* srf04
- Add power management with DT bindings for the GPIO.
* stm32-timer-trigger
- Power management.
* (counter) stm32-timer-cnt
- Power management.
* vcnl4000
- Enable runtime PM for devices that don't use on demand measurement.
Cleanups and minor fixes
* core
- Avoid double read when using debugfs. Whilst we provide no guarantees
on lack of side effects using the debugfs interfaces, this one is
generate unexpected results so let us tidy it up.
* dac/Kconfig
- Alphabetic order.
* ad5755
- Grammar and minor other fixes.
* ad7124
- Fail probe if get_voltage fails as no meaningful readings can be had
without knowing the external reference.
- Switch to selection between different channel attributes rather than
building the arrays at runtime.
- Remove the spi_device_id table as the driver cannot be probled without
more information that can be provided without dt.
- Update sysfs docs to provide more inormation and bring remaining docs for
this part out of staging.
* ad9292
- Use new SPI transfer delay structure.
* adis library
- Add unlocked version of adis_initial_startup and refactor the function.
- Add a product ID santiy check.
- Add support for different self test registers.
- Use new SPI delay structure.
- Add new docs and tidy up existing.
* adis16136
- Initialize adis_data statically.
* adis16400
- Initialize adis_data statically.
* adis16460
- Use core __adis_initial_Startup now it supports everything needed.
* adis16480
- Initialize adis_data statically.
- Use core __adis_initial_startup now it supports everything needed.
* al3320a
- Add missing DT binding docs.
- Tidy up code formatting.
- Simplify error paths using devm_add_action_or_reset.
- Ensure autoloading works by adding the of_match_table.
* atlas-sensor
- Drop false requirement for interrupt line, the value can be polled using
a sysfs or hrtimer type trigger.
* exynos-adc
- Silence warning message on deferring probe.
* gp2ap002
- Greatly simplify the Lux LUT.
- Reorder actions around buffer setup and tear down as part of a sub-system
wide standardization of these.
* inv_mpu6050
- Various lttle tidyups.
- Simpliy I2C aux MUX handling by enabling it only at startup. It never
needs to be disabled.
- Simplify polling rate when magnetometer enabled by putting only under
control of userspace.
- Always execute full reset on devices supporting spi. It does no harm
when using i2c and makes for simpler code.
- Reduce over the top sleep times for vddio regulator power up.
- Greatly simplify power and engine management.
- Fix some delays in polled reads (only visible due to other changes)
- Stop preventing sampling rate changes whilst running as there is no
adverse consequence of doing so.
- Prevent attempting to read the temperature if neither accel nor
gyro is enabled.
* lmp9100
- Reorder actions around buffer setup and tear down as part of a sub-system
wide standardization of these.
* max1118
- Use new SPI transfer delay structure.
* mcp320x
- Use new SPI transfer delay structure.
* si1133
- Read full 24 bit signed integer instead o dropping last 8 bits of value.
Not a critical fix as just adds precision.
* st_sensors
- Use st_sensors_dev_name_probe instead of open coded version in st_accel
- Handle potential memory allocation failure.
* st_lsm6dsx
- Fix some wrong structure element naming in documentation.
- Add missing return value check.
* stm32_timer_cnt
- Drop some unused left over IIO headers from this count subsystem driver.
- Ensure the clock is enabled in master mode. Theoretical issue rather
than one known to happen in the wild.
* tlc4541
- Use new SPI delay structure.

staging: mt7621-pci: fix io space and properly set resource limits
Function 'mt7621_pci_parse_request_of_pci_ranges' is using
'of_pci_range_to_resource' to get both mem and io resources.
Internally this function calls to 'pci_address_to_pio' which
returns -1 if io space address is an address > IO_SPACE_LIMIT
which is 0xFFFF for mips. This mt7621 soc has io space in physical
address 0x1e160000. In order to fix this, overwrite invalid io
0xffffffff with properly values from the device tree and set
mapped address of this resource as io port base memory address
calling 'set_io_port_base' function. There is also need to properly
setup resource limits and io and memory windows with properly
parsed values instead of set them as 'no limit' which it is wrong.
For any reason I don't really know legacy driver sets up mem window
as 0xFFFFFFFF and any other value seems to does not work as expected,
so set up also here with same values.
