Apologies, I missed your emails. I am fine with those, happy to fixup
anything if the linux-next screams.

Hi Andy,
Thanks for the review. I will address the comments in v2.
You are right. The driver does not have a hard dependency on OF.
It only uses the OF match table for Device Tree based probing, but the
driver itself can use generic device APIs and does not need to be limited
to OF-only systems.
I will drop the `depends on OF` dependency and use generic match-data
handling where applicable.

There is no special reason to use iowrite32() here. This is a normal
MMIO resource, so I will switch the driver to readl()/writel().

This IP block currently has only one clock input, so I used the unnamed clock.
Since there is no ambiguity for the current hardware, I would prefer to keep
the binding simple unless a named clock is required.

FIELD_PREP_CONST() cannot be used here because the channel-enable value is
derived from soc_data->num_channels, which is runtime match data.

From: Stefano Radaelli <stefano.r@variscite.com>
Add device tree support for the Variscite DART-MX8MP system on module.
This SOM is designed to be used with various carrier boards.
The module includes:
- NXP i.MX8M Plus MPU processor
- Up to 8GB 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.

* [PATCH v4 0/3] Add support for Variscite DART-MX8M-PLUS and Sonata board
From: Stefano Radaelli @ 2026-06-09 9:04 UTC (permalink / raw)
To: linux-kernel, devicetree, imx, linux-arm-kernel

This patch series adds support for the Variscite DART-MX8M-PLUS
system on module and the Sonata carrier board.
The series includes:
- SOM device tree with on-module peripherals
- Sonata carrier board device tree with board-specific features
The implementation follows the standard SOM + carrier board pattern
where the SOM dtsi contains only peripherals mounted on the module,
while carrier-specific interfaces are enabled in the board dts.
v3->v4:
- Add snvs nodes
v2->v3:
- Fixed wrong som eth phy address
v1->v2:
- Fixed wrong sai peripheral reference
- Fixed wrong eqos pinctrl gpio
- Fixed model name
- Added new usdhc2 regulator pinctrl
- Adjusted irq edges

Apologies, it did. I will pick this up, if we have sufficient fixes,
I might send it as fixes for v7.2, otherwise , queue it for v7.3

From: Stefano Radaelli <stefano.r@variscite.com>
Add device tree support for the Variscite DART-MX8MP system on module.
This SOM is designed to be used with various carrier boards.
The module includes:
- NXP i.MX8M Plus MPU processor
- Up to 8GB 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.

* [PATCH v3 0/3] Add support for Variscite DART-MX8M-PLUS and Sonata board
From: Stefano Radaelli @ 2026-06-09 8:57 UTC (permalink / raw)
To: linux-kernel, devicetree, imx, linux-arm-kernel

This patch series adds support for the Variscite DART-MX8M-PLUS
system on module and the Sonata carrier board.
The series includes:
- SOM device tree with on-module peripherals
- Sonata carrier board device tree with board-specific features
The implementation follows the standard SOM + carrier board pattern
where the SOM dtsi contains only peripherals mounted on the module,
while carrier-specific interfaces are enabled in the board dts.
v2->v3:
- Fixed wrong som eth phy address
v1->v2:
- Fixed wrong sai peripheral reference
- Fixed wrong eqos pinctrl gpio
- Fixed model name
- Added new usdhc2 regulator pinctrl
- Adjusted irq edges

I still advocate to keep this BPF_JIT_KASAN, which is used later in
patch 7/8 to check whether kasan tests should be executed or not.

All being well this means that it will be integrated into the linux-next

* [Question] Enabling CoreSight TRBE in firmware on CIX Orion O6
From: Yunseong Kim @ 2026-06-09 8:40 UTC (permalink / raw)

Hi CIX team,
I'm working on vock (https://github.com/yskzalloc/vock), a tool that maps
userspace programs to the exact kernel code they exercise using hardware
trace. On arm64, this relies on CoreSight ETM (--mode hw, for non-kcov
enabled kernel) to collect kernel coverage without requiring CONFIG_KCOV.
Without firmware enabling TRBE or exposing TMC/ETR, I cannot verify or test
the arm64 CoreSight code path on the Orion O6 at all.
I've been testing on a CIX Orion O6 board running Debian sid latest generic kernel
and found that CoreSight trace is not functional due to firmware-level restrictions.
Test environment running Debian sid arm64 kernel:
Board: CIX Orion O6
Kernel: Debian arm64 generic (7.1+unreleased-arm64, CONFIG_CORESIGHT=m)
CPU: Cortex-A520 (0xd81) + Cortex-A720 (0xd80), 12 cores
Firmware: UEFI/ACPI (no device tree)
What works:
- coresight_etm4x module loads successfully
- cs_etm PMU appears at /sys/bus/event_source/devices/cs_etm (type=12)
- nr_addr_filters = 8
$ lsmod | grep coresight
coresight_etm4x 118784 0
coresight 110592 1 coresight_etm4x
$ ls /sys/bus/event_source/devices/cs_etm/type
12
What fails:
1. No CoreSight bus devices are registered:
$ ls /sys/bus/coresight/devices/
(empty)
2. perf AUX mmap fails (no trace sink available):
$ perf record -e cs_etm// -- ls
intel_pt: aux mmap: Cannot allocate memory
3. TRBE module loads but registers no devices (firmware blocks access):
$ sudo modprobe coresight-trbe
$ ls /sys/bus/coresight/devices/
(empty)
4. dmesg shows only configuration manager, no ETM/TRBE device probes:
[ 4479.881313] cs_system_cfg: CoreSight Configuration manager initialised
5. DSDT has no CoreSight ACPI devices (no ARMHC500/ARMHC501/ARMHC97C HIDs)
Root cause:
The Cortex-A520 and Cortex-A720 cores support both ETM and TRBE in
hardware, but the firmware (TF-A/EL3) does not enable OS-level access:
- TRBE: MDCR_EL3.NSTBE is likely not set, preventing non-secure
trace buffer access
- TMC/ETR: No MMIO-mapped trace sinks are described in the ACPI DSDT
- Self-hosted trace: MDCR_EL3.NSTB / CPTR_EL3.TTA may not be configured
Can you check enabling CoreSight trace support in the Orion O6 firmware by either:
(1) (Preferred) Enable TRBE access from non-secure EL1/EL2:
- Set MDCR_EL3.NSTBE = 1 in TF-A
- This allows the per-CPU Trace Buffer Extension to work as a sink
without any additional MMIO hardware
(2) Or expose the full CoreSight topology in ACPI:
- Add ARMHC97C (TMC-ETR) device with MMIO base address
- Add ARMHC502 (funnel) devices if applicable
- Reference: ARM DEN0067 (CoreSight Architecture ACPI bindings)
(1) is simpler and doesn't require ACPI table changes, it's a single register
bit in the secure firmware.
Thank you!
Best regards

Thank you for sending the AI review.
Please find my comments:
- I've gone through them and yes, there are a few issues found.
However, those are IMHO not critical ones.
- Some issues are not valid at all - like concern what happens when the
switch is run on multi processor chip - both imx287 and vf610 are
single core chips.
- It seems like the AI review is "progressing" - i.e. there were no
issues found with v23 for this particular patch. I do guess that the
new Orc Mode from [1] has found it.
- I do guess that different AI agent would generate different review
- The aforementioned issues could be addressed with a fix patches -
dragging along (and preparing for upstream) patch set with ~3400
LOC (which is rejected by non-deterministic AI review) takes too much
resources now.
To sum up:
----------
The MTIP driver for v6.6 kernel (YPRR Scarthgap) with and without
PREEMPT_RT for vf610 and imx287 as well as the v24 for net-next can be
found at [2].

* [PATCH] regulator: mt6359: Fix vbbck default internal supply name
From: Chen-Yu Tsai @ 2026-06-09 8:36 UTC (permalink / raw)

This issue was pointed out by Sashiko.
vbbck is fed internally from vio18. For the MT6359, the default supply
name was incorrectly set as "VIO18", instead of the supply's default
"VIO18". In practice this still works, but it causes the regulator
description copy and replace to always happen. For the MT6359P the
name is correct.
Fix the supply name for MT6359 so that both instances are the same and
correct. Also copy the comment about the internal supply from the MT6359
list to the MT6359P list.
Fixes: 10be8fc1d534 ("regulator: mt6359: Add regulator supply names")
