Total fine. Bindings and drivers can be 1:1, N:1 or 1:N.

as an example.

+ The AST2600 SoC provides a shared I3C global register block used by all
+ I3C controller instances. This block contains per-instance global
+ configuration fields, including controller instance ID and SDA pull-up
+ configuration.
+ Each I3C controller references this syscon node through the
+ aspeed,global-regs property.

* [PATCH v3 2/3] ARM: dts: aspeed-g6: Add nodes for i3c controllers

In-Reply-To: <cover.1775679285.git.dawid.glazik@linux.intel.com>
Add the i3c controller devices to the ast2600 g6 common dts. We add all
6 busses to the common g6 definition, but leave disabled through the
status property, to be enabled per-platform.

v3:
- add i3c aliases
- rebase on top of latest tree and solve conflicts
- as agreed with Jeremy off-list, he said I can take authorship of this going forward
v2:
- use inline bus representation, without the i3c: label

* [PATCH v3 1/3] ARM: dts: aspeed-g6: move i2c controllers directly into apb node
From: Dawid Glazik @ 2026-04-08 20:34 UTC (permalink / raw)
To: Alexandre Belloni, Rob Herring, Krzysztof Kozlowski, Conor Dooley,
Joel Stanley, Andrew Jeffery, linux-aspeed
Cc: linux-i3c, devicetree, linux-arm-kernel, Frank Li, Dawid Glazik,
Maciej Lawniczak, Jeremy Kerr
In-Reply-To: <cover.1775679285.git.dawid.glazik@linux.intel.com>
We currently have the apb's mapping of the i2c controller space as a
labelled mostly-empty node:
apb {
i2c: bus@1e78a000 {
ranges = <...>;
};
}
... and then define the contents of the i2c block later:
i2c: {
i2c0: i2c-bus@80 {
reg = <0x80 0x80>;
};
i2c1: i2c-bus@100 {
reg = <0x100 0x80>;
};
}
Krzysztof mentions[1] that isn't convention though, with the top-level
simple-bus being empty and linked via the label. So, drop the label
usage and move the i2c bus definition into the simple-bus node directly
under the apb:
apb {
bus@1e78a000 {
ranges = <...>;
i2c0: i2c-bus@80 {
reg = <0x80 0x80>;
};
i2c1: i2c-bus@100 {
reg = <0x100 0x80>;
};
};
}
This will allow us to be consistent when we add new definitions for the
i3c nodes, which would require the latter format.

* [PATCH v3 0/3] ARM: dts: aspeed-g6: add AST2600 I3C nodes and bindings
From: Dawid Glazik @ 2026-04-08 20:34 UTC (permalink / raw)
To: Alexandre Belloni, Rob Herring, Krzysztof Kozlowski, Conor Dooley,
Joel Stanley, Andrew Jeffery, linux-aspeed
Cc: linux-i3c, devicetree, linux-arm-kernel, Frank Li, Dawid Glazik,
Maciej Lawniczak
This series reworks and resubmits AST2600 I3C DTS updates that were
originally posted in 2024, but stalled without further upstream
progress.[1] The series was rebased onto the current tree and merge
conflicts were resolved.
The patches first move i2c nodes under the APB simple-bus for layout
consistency, then add AST2600 I3C controller nodes in aspeed-g6.dtsi
and finally add the missing dt-binding for AST2600 I3C global
registers. Jeremy agreed in a separate email thread that I can continue
this series under my authorship.

* [PATCH v5 0/6] arm64: dts: qcom: Support AYN QCS8550 Devices
From: Aaron Kling via B4 Relay @ 2026-04-08 19:41 UTC (permalink / raw)
To: Bjorn Andersson, Konrad Dybcio, Rob Herring, Krzysztof Kozlowski,
Conor Dooley
Cc: linux-arm-msm, devicetree, linux-kernel, Aaron Kling, Xilin Wu,
Krzysztof Kozlowski, Teguh Sobirin, Konrad Dybcio
This specifically includes:
* Odin 2 Mini
* Odin 2 Portal
* Thor
The original Odin 2 dts is not currently included as it has not yet
been verified.
The initial port was done by Teguh Sobirin for ROCKNIX and was made
available on the AYN github [0].
Support has been removed for things not yet supported by the upstream
kernel, these will be added later when the related drivers are submitted
and picked up. Such includes:
* All panels
* The Odin 2 Mini backlight and touch
* All rgb leds
* The built-in uart gamepad

I'd like to get a clearer steer from the PCIe and DT maintainers
before investing further in either direction.
To recap the two approaches on the table:
Option 1: A single renesas,pcie-controller-id property used to look up
SYSC offsets in the driver.
Option 2: Explicit per-controller DT properties carrying the SYSC
phandle, register offset, and mask for each functionality
(L1 allow, mode, link-master, etc.).
Both have trade-offs. Option 1 is simpler in the DT but moves hardware
knowledge into the driver, tightening the coupling. Option 2 is more
verbose but fully describes the hardware topology in the DT and avoids
a driver-internal lookup table.
Are there other approaches the maintainers would prefer that we
haven't considered?
Any guidance on the preferred direction or examples of similar solved
problems in the tree would be very appreciated.
Cheers,
Prabhakar

Add bindings and description for SolidRUn i.MX8DXL based SoM and
HummingBoard Telematics.
This patch-set is based on v7.0-rc2, because rc1 was experiencing
deadlocks with imx8qxp clock driver.

Add support for the SolidRun i.MX8DXL System-on-Module (revision 2.1)
and its corresponding evaluation carrier board, the HummingBoard
Telematics (revision 2.0).
The SoM features:
- eMMC
- GNSS with 1PPS
- V2X DSRC Radio
- Secure Element for V2X Applications
- Inertial Sensor
- Pressure Sensor
- Compass
The HummingBoard Telematics carrier board features:
- Cellular Modem
- WiFi & Bluetooth
- RTC with backup battery
- CAN
- 100Base-TX Ethernet
- 100Base-T1 Ethernet
- Multi-interface I/O connector
- Multi-interface add-on board connector
The multi-interface I/O connector supplies power and provides basic I/O
(Console UART, 100Base-TX, 100Base-T1, CAN, and power-supply logic level
GPIOs). The SolidRun Evaluation Kit includes a suitable cable and
adapter board that breaks these out into RJ45, USB Type-A, microUSB
Console, and Terminal Block connectors.
The multi-interface add-on board connector provides additional
interfaces (4x 100Base-T1, 2x SGMII, USB 2.0 shared with the cellular
modem, CAN, MDIO, SPI, UART, PCIe, I2C, and GPIO). These add-on
interfaces are disabled by default in the base device tree and are
intended to be enabled and extended via device tree overlays.
Note that a few components physically present on the SoM were omitted
from this description due to a lack of upstream bindings and drivers:
- Pressure Sensor
- V2X DSRC Radio
- Secure Element

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,

* [PATCH v3 4/4] arm64: dts: rockchip: add analog audio to ROCK 4D
From: Nicolas Frattaroli @ 2026-04-08 17:49 UTC (permalink / raw)
To: Dmitry Torokhov, Rob Herring, Krzysztof Kozlowski, Conor Dooley,
Alexandre Belloni, Heiko Stuebner
Cc: kernel, linux-input, devicetree, linux-kernel, linux-arm-kernel,

In-Reply-To: <20260408-rock4d-audio-v3-0-49e43c3c2a68@collabora.com>
The RADXA ROCK 4D, like many other Rockchip-based boards, uses an ES8388
analog audio codec. On the production version of the board, the codec's
LOUT1 and ROUT1 pins are tied to the headphone jack, whereas pins LOUT2
and ROUT2 lead to a non-populated speaker amplifier that itself leads to
a non-populated speaker jack. The schematic is still haunted by the
ghosts of those symbols, but it clearly marks them as "NC".
The 3.5mm TRRS jack has its microphone ring (and ground ring) wired to
the codec's LINPUT1 and RINPUT1 pins for differential signalling.
Furthermore, it uses the SoCs ADC to detect whether the inserted cable
is of headphones (i.e., no microphone), or a headset (i.e., with
microphone). The way this is done is that the ADC input taps the output
of a 100K/100K resistor divider that divides the microphone ring pin
that's pulled up to 3.3V.
There is no ADC level difference between a completely empty jack and one
with a set of headphones (i.e., ones that don't have a microphone)
connected. Consequently headphone insertion detection isn't something
that can be done.
Add the necessary codec and audio card nodes. The non-populated parts,
i.e. LOUT2 and ROUT2, are not modeled at all, as they are not present on
the hardware.
Also, add an adc-keys node for the headset detection, which uses an
input type of EV_SW with the SW_MICROPHONE_INSERT keycode. Below the
220mV pressed voltage level of our SW_MICROPHONE_INSERT switch, we also
define a button that emits a KEY_RESERVED code, which is there to model
this part of the voltage range as not just being extra legroom for the
button above it, but actually a state that is encountered in the real
world, and should be recognised as a valid state for the ADC range to be
in so that no "closer" ADC button is chosen.

Rework the probe function, and functions called by the probe function,
to use dev_err_probe for error logging.
While at it, also do some minor style cleanups, like not error logging
on -ENOMEM and using ! instead of == 0.

Instead of doing something like what gpio-keys is doing, adc-keys
hardcodes that all keycodes must be of type EV_KEY.
This limits the usefulness of adc-keys, and overcomplicates the code
with manual bit-setting logic.
Instead, refactor the code to read the linux,input-type fwnode property,
and get rid of the custom bit setting logic, replacing it with
input_set_capability instead. input_report_key is replaced with
input_event, which allows us to explicitly pass the type.
Only EV_KEY and EV_SW is allowed at this stage.

adc-keys, unlike gpio-keys, does not allow linux,input-type as a valid
property. This makes it impossible to model devices that have ADC inputs
that should generate switch events.
Replace "additionalProperties" with "unevaluatedProperties", so that any
of the properties in the referenced input.yaml schema can be used.
Consequently, throw out the explicit mention of "linux,code" and extend
the example to verify.

* [PATCH v3 0/4] ROCK 4D audio enablement
From: Nicolas Frattaroli @ 2026-04-08 17:49 UTC (permalink / raw)

Cristian Ciocaltea
The ROCK 4D uses an ADC input to distinguish between a headphone (i.e.,
no mic) and a headset (i.e., with mic). After some searching, it appears
that the closest we can get to modelling this is by sending a particular
switch input event.
So this series modifies the adc-keys bindings, extends the adc-keys
driver to allow sending other input types as well, and then adds the
analog audio nodes to ROCK 4D's device tree.
It should be noted that analog capture from the TRRS jack currently
results in completely digitally silent audio for me, i.e. no data other
than 0xFF. There's a few reasons why this could happen, chief among them
that my SAI driver is broken or that the ES8328 codec driver is once
again broken. The DAPM routes when graphed out look fine though. So the
DTS part is correct, and I can fix the broken capture in a separate
follow-up patch that doesn't have to include DT people.
Another possibility is that my phone headset, despite being 4 rings and
having a little pin hole at the back of the volume doodad, does not
actually have a microphone, but in that case I'd still expect some noise
in the PCM. Maybe it's just shy.

In-Reply-To: <cover.1775669847.git.stefano.r@variscite.com>
From: Stefano Radaelli <stefano.r@variscite.com>
Add device tree support for the Variscite VAR-SOM-MX91 system on module.
This SOM is designed to be used with various carrier boards.
The module includes:
- NXP i.MX91 MPU processor
- Up to 2GB of LPDDR4 memory
- Up to 128GB of eMMC storage memory
- Integrated 10/100/1000 Mbps Ethernet Transceiver
- Codec audio WM8904
- WIFI6 dual-band 802.11ax/ac/a/b/g/n with optional 802.15.4 and Bluetooth
Only SOM-specific peripherals are enabled by default. Carrier board
specific interfaces are left disabled to be enabled in the respective
carrier board device trees.
