Merge series from David Lechner <dlechner@baylibre.com>:
This series is adding support for SPI controllers and peripherals that
have multiple SPI data lanes (data lanes being independent sets of
SDI/SDO lines, each with their own serializer/deserializer).
This series covers this specific use case:
+--------------+ +---------+
| SPI | | SPI |
| Controller | | ADC |
| | | |
| CS0 |--->| CS |
| SCLK |--->| SCLK |
| SDO |--->| SDI |
| SDI0 |<---| SDOA |
| SDI1 |<---| SDOB |
| SDI2 |<---| SDOC |
| SDI3 |<---| SDOD |
+--------------+ +--------+
The ADC is a simultaneous sampling ADC that can convert 4 samples at the
same time. It has 4 data output lines (SDOA-D) that each contain the
data of one of the 4 channels. So it requires a SPI controller with 4
separate deserializers in order to receive all of the information at the
same time.
This should also work for the use case in [1] as well. (Some of the
patches in this series were already submitted there). In that case the
SPI controller is used kind of like it is two separate SPI controllers,
each with its own chip select, clock, and data lines.
[1]: https://lore.kernel.org/linux-spi/20250616220054.3968946-1-sean.anderson@linux.dev/
The DT bindings are a fairly straight-forward mapping of which pins on
the peripheral are connected to which pins on the controller. The SPI
core code parses this and makes the information available to drivers.
When a peripheral driver sees that multiple data lanes are wired up, it
can chose to use them when sending messages.
The SPI message API is a bit higher-level than just specifying the
number of data lines for a SPI transfer though. I did some research on
other SPI controllers that have this feature. They tend to be the kind
meant for connecting to two flash memory chips at the same time but can
be used more generically as well. They generally have the option to
either use one lane at a time (Sean's use case), or can mirror the same
data on multiple lanes (no users of this yet) or can perform striping
of a single data FIFO/DMA stream to/from the two lanes (our use case).
For now, the API assumes that if you want to do mirror/striping, then
you want to use all available data lanes. Otherwise, it just uses the
first data lane for "normal" SPI transfers.

IIO: New device support, features and cleanup for the 6.20/7.0 cycle.
Slightly messier than normal unfortunately due to some conflicts
and build config bugs related to I3C drivers.
One last minute Kconfig fix right at the top after a linux-next report.
I've simplified the Kconfig and made it match other instances in the kernel
so that should be safe enough despite short soak time in front of build bots.
Merge of an immutable branch from I3C to get some stubs that were missing
and caused build issues with dual I2C / I3C drivers. This also brought in a
drop of some deprecated interfaces so there is also one patch to update a
new driver to not use those.
We are having another go at using cleanup.h magic with the IIO mode claim
functions after backing out last try at this. This time we have wrappers
around the new ACQUIRE() and ACQUIRE_ERR() macros.
Having been burnt once, we will be taking it a bit more slowly this time
wrt to wide adoption of these! Thanks in particular to Kurt for taking
on this core IIO work.
New Device Support
==================
adi,ad18113
- New driver to support the AD18113 amplifier - an interesting device due
to the external bypass paths where we need to describe what gain those
paths have in DT. Longer term it will be interesting to see if this
simplistic description is enough for real deployments.
adi,ad4062
- New driver for the AD4060 and AD4052 SAR ADCs including trigger, event
and GPIO controller support. Follow up patch replaced use of some
deprecated I3C interfaces prior to the I3C immutable branch merge as
that includes dropping them.
adi,ad4134
- New driver for the AD4134 24bit 4 channel simultaneous sampling ADC.
adi,ad7768-1,
- Add support for the ADAQ767-1, ADAQ7768-1 and ADAQ7769-1 ADCs after some
rework to enable the driver to support multiple device types.
adi,ad9467
- Add support for the similar ad9211 ADC to this existing driver.
- Make the selection of 2s comp mode explicit for normal operation and
switch to offset binary when entering calibration mode.
honeywell,abp2
- New driver to support this huge family (100+) of board mount pressure and
temperature sensors.
maxim,max22007
- New drier for this 4 channel DAC.
memsic,mmc5633
- New driver for this I2C/I3C magnetometer. Follow on patches fixed up
issues related to single driver supporting both bus types.
microchip,mcp747feb02
- New driver for the Microchip MCP47F(E/V)B(0/1/2)1,
MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8
buffered voltage output DACs.
nxp,sar-adc
- New driver support ADCs found on s32g2 and s32g3 platforms.
ti,ads1018
- New drier for the ADS1018 and ADS1118 SPI ADCs.
ti,ads131m02
- New driver supporting ADS131M(02/03/04/06/08)24-bit simultaneous sampling
ADCs.
Features
========
iio-core
- New IIO_DEV_ACQUIRE_DIRECT_MODE() / IIO_DEV_ACQUIRE_FAILED() +
equivalents for the much rarer case where the mode needs pinning
whether or not it is in direct mode. These use the ACQUIRE()
/ ACQUIRE_ERR() infrastructure underneath to provide both simple
checks on whether we got the requested mode and to provide scope
based release. Applied in a few initial drivers.
adi,ad9467
- Support calibbias control
adi,adf4377
- Add support to act as a clock provider.
adi,adxl380
- Support low power 1KHz sampling frequency mode. Required rework of
how events and filters were configured, plus applying of constraints
when in this mode.
rf-digital,rfd77402
- Add interrupt support as alternative to polling for completion.
st,lsm6dsx
- Tap event detection (after considerable driver rework)
Cleanup and Minor Fixes
=======================
More minor cleanup such as typos, white space etc not called out except
where they were applied to a lot of drivers.
Various drivers.
- Use of dev_err_probe() to cleanup error handling.
- Introduce local struct device and struct device_node variables to
reduce duplication of getting them from containing structs.
- Ensure uses of iio_trigger_generic_data_rdy_poll() set IRQF_NO_THREAD
as that function calls non threaded child interrupt handlers.
- Replace IRQF_ONESHOT in not thread interrupt handlers with
IRQF_NO_THREAD to ensure they run as intended. Drop one unnecessary case.
iio-sw-device/trigger.
- Constify configs_group_operations structures.
iio-buffer-dma / buffer-dma-engine
- Use lockdep_assert_held() to replace WARN_ON() to check lock is
correctly held.
- Make use of cleanup.h magic to simplify various code paths.
- Make iio_dma_buffer_init() return void rather than always success.
adi,ad7766
- Replace custom interrupt handler with iio_trigger_generic_data_rdy_poll()
adi,ad9832
- Drop legacy platform_data support.
adi,ade9000
- Add a maintainer entry.
adi,adt7316
- Move to EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() so the compiler
can cleanly drop unused pm structures and callbacks.
adi,adxl345
- Relax build constraint vs the driver that is in input so both may be
built as modules and selection made at runtime.
adi,adxl380
- Make sure we don't read tail entries in the hardware fifo if a partial
new scan has been written.
- Move to a single larger regmap_noinc_read() to read the hardware fifo.
aspeed,ast2600
- Add missing interrupts property to DT binding.
bosch,bmi270_i2c
- Add missing MODULE_DEVICE_TABLE() macros so auto probing of modules can
work.
bosch,smi330
- Drop duplicate assignment of IIO_TYPE in smi330_read_avail()
- Use new common field_get() and field_prep() helpers to replace local
version.
honeywell,mprls0025pa
Fixes delayed to merge window as late in cycle and we didn't want to delay
the rest of the series.
- Allow Kconfig selection of specific bus sub-drivers rather than tying that
to the buses themselves being supported.
- Zero spi_transfer structure to avoid chance of unintentionally set fields
effecting transfer.
- Fix a potential timing violation wrt to the chip select to first clock
edge timing.
- As recent driver, take risk inherent in dropping interrupt direction from
driver as that should be set by firmware.
- Fix wrong reported number of data bits for channel.
- Fix a pressure channel calculation bug.
- Rework to allow embedding the tx buffer in the iio_priv() structure rather
than requiring separate allocation.
- Move the buffer clearing to the shared core bringing it into affect for
SPI as well as I2C.
- Stricter checks for status byte.
- Greatly simplify the measurement sequence.
- Add a copyright entry to reflect Petre's continued work on this driver.
intersil,isl29018
- Switch from spritnf to sysfs_emit_at() to make it clear overflow can't
occur.
invensense,icm42600
- Allow sysfs access to temperature when buffered capture in use as it
does not impact other sensor data paths.
invensense,itg3200
- Check unused return value in read_raw() callback.
men,z188
- Drop now duplicated module alias.
rf-digital,rfd77402
- Add DT binding doc and explicit of_device_id table.
- Poll for timeout with times as on datasheet, then replace opencoded
version with read_poll_timeout().
sensiron,scd4x
- Add missing timestamp channel. The code to push it to the buffer was there
but there was no way to turn it on.
vti,sca3000
- Fix resource leak if iio_device_register() fails.

Add a binding for the Anbernic RG-DS Amplifier, which is an Awinic
aw87391 audio amplifier. This manufacturer did not provide firmware
so we have to use a list of init commands instead, requiring device
specific functionality rather than generic aw87391 functionality.

Extend the ADI AXI SPI engine binding for multiple data lanes. This SPI
controller has a capability to read multiple data words at the same
time (e.g. for use with simultaneous sampling ADCs). The current FPGA
implementation can support up to 8 data lanes at a time (depending on a
compile-time configuration option).

Add spi-tx-lane-map and spi-rx-lane-map properties to the SPI peripheral
device tree binding. These properties allow specifying the mapping of
peripheral data lanes to controller data lanes. This is needed e.g. when
some lanes are skipped on the controller side so that the controller
can correctly route data to/from the peripheral.

Change spi-rx-bus-width and spi-tx-bus-width properties from single
uint32 values to arrays of uint32 values. This allows describing SPI
peripherals connected to controllers that have multiple data lanes for
receiving or transmitting two or more words in parallel.
Each index in the array corresponds to a physical data lane (one or more
wires depending on the bus width). Additional mapping properties will be
needed in cases where a lane on the controller or peripheral is skipped.
Bindings that make use of this property are updated in the same commit
to avoid validation errors.
The adi,ad4030 binding can now better describe the chips multi-lane
capabilities, so that binding is refined and gets a new example.
Converting from single uint32 to array of uint32 does not break .dts/
.dtb files since there is no difference between specifying a single
uint32 value and an array with a single uint32 value in devicetree.

Convert the ASpeed fan controller binding to DT schema format.
The '#size-cells' value is 0 rather 1.
Some users define more that 8 fan nodes where 2 fans share a PWM. The
driver seems to let the 2nd fan just overwrite the 1st one. That also
creates some addressing errors in the DT (duplicate addresses and wrong

The `interrupts` property indicates an RTC alarm interrupt, which is

Changing the `allowed` property is ABI-breaking behavior, but
throughout the existing Loongson DTS{i}, the description of the RTC
nodes conforms to the modified bingding rules.
Thus, the existing Loongson DTS{i} will not be affected.

For 32-bit Altera SoCFPGA parts, the sys-mgr uses the syscon as a fallback.
This change addresses this warning from dtbs_check:
sysmgr@ffd08000 (altr,sys-mgr): compatible: 'oneOf' conditional failed, one
must be fixed:
['altr,sys-mgr', 'syscon'] is too long
'altr,sys-mgr-s10' was expected
'altr,sys-mgr' was expected
from schema $id: http://devicetree.org/schemas/soc/altera/altr,sys-mgr.yaml

For all SoCFPGA platforms, whether it has the "intel" or "altr" vendor
prefix are referring to the same business unit that is responsible for
the platform. And now that Altera has spun off to be a separate corporate
entity from Intel, it would make sense to have the device bindings
documentation in the same file.
Move the Intel AgileX board binding documentations into the same file that
contains the Altera ones.

The firmware-name property was originally introduced to allow end-users
and integrators to select use-case-specific firmware for the WCN6855.
However, specifying firmware for an M.2 WLAN module in the Device Tree
is not appropriate. Instead, this functionality will be handled within
the ath11k driver. Therefore, the firmware-name property is now
deprecated.

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies). Split qcom,wcn7850-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties. Re-shuffle few properties to alphabetical order
while moving them and drop redundant enable-gpios description.
This makes the source qualcomm-bluetooth.yaml binding empty, thus drop
it making entire change a variant of file rename.

Extend the existing Tegra186 GPIO controller device tree bindings with
support for the GPIO controller found on Tegra264. The number of pins
is slightly different, but the programming model remains the same.
Add a new header, include/dt-bindings/gpio/nvidia,tegra264-gpio.h,
that defines port IDs as well as the TEGRA264_MAIN_GPIO() helper,
both of which are used in conjunction to create a unique specifier
for each pin.
On Tegra, GPIO wake events are latched and routed via the PMC.
Document the standard DT property, wakeup-parent, which is a phandle to
the PMC interrupt controller that provides the parent wake interrupt
domain for the GPIO controller. If the property is absent the driver
falls back to a compatible-based lookup.

RISC-V Devicetrees for v6.20 (or v7.0)
Anlogic:
Minor change to the extension information, to add the "b" extension
that's a catch-all for 3 of the extensions already in the dts.
Starfive:
Append the jh7110 compatible to jh7110s devicetrees, as that will enable
OpenSBI etc to run without adding support for this minor variant. The
"s" device differs from the non "s" device only in
thermal limits and voltage/frequency characteristics.
Microchip:
Redo the mpfs clock setup yet again, to something approaching correct.
The original binding conjured up for the platform was wildly inaccurate,
and even with the original improvements, a bigger change to using
syscons was required to support several peripherals that also inhabit
the memory regions that the clocks lie in. The damage to the dts isn't
that bad in the end, and of course the whole thing has been done in a
backwards compatible manner, with the code changes being merged a cycle
or two ago in the kernel and like a year ago in U-Boot (the only other
user that I am aware of).
Generic:
Additions to extensions.yaml, mainly for things in the "rva23" profile
that appear for the first time on the Spacemit K3 SoC.
