From: Sherry Sun <sherry.sun@nxp.com>
The i.MX8QM-MEK has the PCIe M.2 Mechanical Key E connector to connect
wireless connectivity cards over PCIe and UART interfaces. Hence,
describe the connector node and link it with the PCIe a Root Port and
LPUART1 nodes through graph port/endpoint.
The M.2 Key E connector is powered by a 3.3V fixed regulator
(reg_3v3) on board.

From: Sherry Sun <sherry.sun@nxp.com>
Power supply to the M.2 Bluetooth device attached to the host using M.2
connector is controlled using the 'uart' pwrseq device. So add support for
getting the pwrseq device if the OF graph link is present. Once obtained,
the existing pwrseq APIs can be used to control the power supplies of the
M.2 card.

In-Reply-To: <20260618101047.4185497-1-sherry.sun@oss.nxp.com>
From: Sherry Sun <sherry.sun@nxp.com>
88W9098 is a NXP Wi-Fi/BT combo chip with PCI device ID 0x2b43 under
Marvell Extended vendor ID. AW693 is a NXP Wi-Fi/BT combo chip with
PCI device ID 0x3003 under NXP/Philips vendor ID.
Add both chips to pwrseq_m2_pci_ids[] so that the pwrseq-pcie-m2 driver
can create the Bluetooth serdev device when these cards are inserted into
a PCIe M.2 Key E connector.
Both chips use "nxp,88w8987-bt" as the serdev compatible string, which
is the entry point for the btnxpuart driver. The driver identifies the
actual chip variant at runtime via chip ID auto-detection and loads the
appropriate firmware accordingly.

Use dw_pcie::skip_pwrctrl_off to avoid powering off devices during suspend
to preserve wakeup capability of the devices and also not to power on the
devices in the init path.
This allows controller power-off to be skipped when some devices(e.g. M.2
cards key E without auxiliary power) required to support PCIe L2 link state
and wake-up mechanisms.

* [PATCH 0/8] Add PCIe M.2 Key E connector support for NXP i.MX boards

From: Sherry Sun <sherry.sun@nxp.com>
This series adds support for NXP Wi-Fi/BT combo chips (88W9098, AW693)
inserted into PCIe M.2 Key E connectors on several i.MX EVK/MEK boards.
For M.2 cards that rely on PCIe L2 link state and wake-up mechanisms, the
card must remain powered during suspend. Patch 1 uses the existing
dw_pcie_rp::skip_pwrctrl_off flag to skip power-off during suspend and skip
power-on during the init path.
Alsp the btnxpuart driver is extended to obtain a pwrseq descriptor via the
OF graph on the UART controller device in patch 2.

* [PATCH net v2] net: ti: icssg: Fix XSK zero copy TX during application wakeup

emac_xsk_xmit_zc() handles tx xmit for zero copy and gets called
inside napi context. User application wakes up the kernel while
initiating the transmit which triggers napi to start processing
the tx packets. The num_tx check inside emac_tx_complete_packets()
returns early if no packet transfer happen hindering the call
to emac_xsk_xmit_zc(). Remove this check to let application
wakeup initiate zero copy xmit traffic.
Add __netif_tx_lock() to ensure that the TX queue is protected
from concurrent access during the transmission of XDP frames.
This fixes netdev watchdog timeout for long runs.

IIRC this is a leftover of the ETS offload support.
I agree it is righ to just do:
queue = skb->priority % AIROHA_NUM_QOS_QUEUES; /* QoS queue */

I know some users and they don't use RT kernel.
But well, isn't the pattern present in some other gpio controller drivers ?
How it is done in others ?
What is specific in this controller compare to others ?
We take and release spinlock in gpio chip .irq_enable(). I think we can
find other drivers doing that and probably drivers using a regmap as well.

* [PATCH v4 0/2] clk: amlogic: Add A9 peripherals clock controller
From: Jian Hu via B4 Relay @ 2026-06-18 9:51 UTC (permalink / raw)

This series adds Amlogic A9 peripherals clock support,
including dt-binding and peripherals clock driver.
Note that this driver depends on the A9 PLL driver, which is not yet
upstream. The Meson PLL framework is currently undergoing refactoring,
and the A9 PLL driver will be submitted as a follow-up series after
that work has been completed.

Changes in v4:
- Expose channel 3 for gen_clk.
- Add suffix 0 for some clocks.
- Use helper macro for vclk clocks definitions.
- Drop forward declaration.
- Drop CLK_HW_INIT* and revert to explicit clock declarations.
- Fix can clock channel number comment.
- Rename enc clocks to encoder0/encoder1.
- Link to v3: https://lore.kernel.org/r/20260610-a9_peripherals-v3-0-d07a78085f71@amlogic.com
Changes in v3:
- Add "depend on A9 pll" instructions in the cover-letter.
- Move COMPILE_TEST after 'depends on ARM64' reported by sashiko-bot.
- Fix usb_48m_pre_sel's parent reported by sashiko-bot.
- Fix gen_div width reported by sashiko-bot.
- Fix hdmitx1_pixel's parent reported by sashiko-bot.
- Link to v2: https://lore.kernel.org/r/20260603-a9_peripherals-v2-0-ee1b8c0a1e6c@amlogic.com
Changes in v2:
- Split the A9 clock driver and send the peripherals clock separately.
- Add COMPILE_TEST in Kconfig.
- Drop the 'optional'.
- Rename apb4 to soc.
- Sort the header file.
- Rename hifi to hifi0.
- Use CLK_HW_INIT_PARENTS_DATA to describe clk_init_data.
- Use CLK_HW_INIT_HW to describe clk_init_data.
- Use CLK_HW_INIT_PARENTS_HW to describe clk_init_data.
- Link to v1: https://lore.kernel.org/all/20260511-b4-a9_clk-v1-0-41cb4071b7c9@amlogic.com/

* [PATCH v4 0/2] clk: amlogic: Add A9 AO clock controller
From: Jian Hu via B4 Relay @ 2026-06-18 9:49 UTC (permalink / raw)
To: Neil Armstrong, Jerome Brunet, Michael Turquette, Stephen Boyd,
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Xianwei Zhao,
Kevin Hilman, Martin Blumenstingl
Cc: linux-amlogic, linux-clk, devicetree, linux-kernel,
linux-arm-kernel, Jian Hu, Conor Dooley
This series adds Amlogic A9 AO clock support, including dt-binding and AO clock driver.
Signed-off-by: Jian Hu <jian.hu@amlogic.com>
---
Changes in v4:
- Drop CLK_IS_CRITICAL for ao_xtal_in clock.
- Drop CLK_HW_INIT* and revert to explicit clock declarations.
- Link to v3: https://lore.kernel.org/r/20260610-a9_aoclk-v3-0-b7592d6c31e2@amlogic.com
Changes in v3:
- Move COMPILE_TEST after 'depends on ARM64' reported by sashiko-bot.
- Rename i2c3 to i3c reported by sashiko-bot.
- Reword the comment describing ao_xtal_in's flags.
- Use struct clk_init_data to describe ao_xtal_in's hw.init.
- Link to v2: https://lore.kernel.org/r/20260603-a9_aoclk-v2-0-f47ea616ee78@amlogic.com
Changes in v2:
- Split the A9 clock driver and send the AO clock separately.
- Rename aobus to soc.
- Use CLK_HW_INIT_FW_NAME to describe clk_init_data.
- Use CLK_HW_INIT_PARENTS_DATA to describe clk_init_data.
- Use a9_ao prefix for MESON_COMP_SEL.
- Correct duandiv name.
- Fix pwm b reg.
- Link to v1: https://lore.kernel.org/all/20260511-b4-a9_clk-v1-0-41cb4071b7c9@amlogic.com/

The hardware should dictate this, not the driver/subsystem/maintainer
boundaries. Looking at the register numbers used by the drivers, and
assuming that the audss_cru label in the dts patch means the TRM also
calls this a single Clock-Reset-Unit, I'd say Conor has a point.

The latter. I'm fine with conversion that happens while the code is

* [PATCH v10 3/4] dt-bindings: clock: imx95-blk-ctl: Define formatter child node schema
From: guoniu.zhou @ 2026-06-18 9:41 UTC (permalink / raw)
To: Mauro Carvalho Chehab, Rob Herring, Krzysztof Kozlowski,

In-Reply-To: <20260618-csi_formatter-v10-0-f23830312ba5@oss.nxp.com>
From: Guoniu Zhou <guoniu.zhou@nxp.com>
The Camera CSR contains control registers for multiple CSI formatter IPs
at different register offsets. Each formatter is an independent hardware
block with its own clock input and media pipeline connection.
Define schema to allow formatter child nodes under nxp,imx95-camera-csr,
with 'reg' property specifying the formatter's register offset within the
CSR address space.
Signed-off-by: Guoniu Zhou <guoniu.zhou@nxp.com>
---
Changes in v10:
- Use single quotes for regex pattern to be consistent (Krzysztof Kozlowski)
- Add formatter subnode binding and camera-csr syscon example
- Update commit title and message
Changes in v9:
- New patch to address the issue of formatter acting as a child node of syscon

In-Reply-To: <20260618-csi_formatter-v10-0-f23830312ba5@oss.nxp.com>
From: Guoniu Zhou <guoniu.zhou@nxp.com>
The i.MX95 CSI pixel formatting module uses packet info, pixel and
non-pixel data from the CSI-2 host controller and reformat them to
match Pixel Link(PL) definition.

Changes in v10:
- Drop syscon parent node from example
- Drop Reviewed-by tags from Frank and Krzysztof due to binding changes
- Add description for reg property
- Add space after formatter@20 before opening brace in example
- Enhance the port description with more detailed information
- Delete the blank line immediately following the endpoint in example
Changes in v9:
- Use direct node instead of syscon wrapper in example
Changes in v8:
- Use standard port reference instead of video-interfaces.yaml
- Add parent syscon node in example to show device integration
- Add required constraints for port@0 and port@1 in ports node
Changes in v7:
- Change compatible to imx95-csi-formatter as IP is i.MX95 specific per Marco's suggestion
