====================
pull-request: can-next 2026-08-18

The first patch is by Sean Nyekjaer, targets the tcan4x5x driver and
puts the device into sleep mode before removing the driver.

Pavel Pisa's patch fixes the colors in the documentation of the TX
buffer FSM of CTU CAN FD driver.

2 patches by Cunhao Lu add support for the rockchip 3588 SoC to the
rockchip CAN-FD driver.

Kuniyuki Iwashima contributes per-netns device unregistration for the
vxcan driver.

Eduard Bostina converts the TI HECC DT bindings doc to DT schema.

Harini T contributes 2 patches to the xilinx_can driver to document
phys and update maintainer.

A patch by bui duc phuc converts the m_can driver to use
of_property_present() for wakeup-source.

Fanbo He's patch fixes a typo in the gs_usb driver.

The last patch is by Markus Schneider-Pargmann and removed not needed
driver_data from the m_can PCI driver.

docs: ctucanfd: fix swapped colors in legend for TX buffer FSM of CTU CAN FD

2026-08-17T17:20:37+00:00

The Inaccessible and Accessible legend colors has been swapped
for many years. As I have helped to clean the CTU CAN FD section
of official documentation for mass produced silicon (multiple
models of microcontrollers) with the company representatives,
I have found the problem and propagate correction bask to
the primary CTU CAN FD sources.

ixd: add basic driver framework for Intel(R) Control Plane Function

2026-08-12T20:56:51+00:00

Add module register and probe functionality. Add the required support to
register IXD PCI driver, as well as probe, remove and shutdown callbacks.
Enable the PCI device and request to reserve the memory resources that will
be used by the driver. Finally map the BAR0 address space.

For now, use devm_kzalloc() to allocate adapter, as it requires the least
amount of code. In a later commit, it will be replaced with a devlink
alternative.

pds_core: add PLDM firmware update support via devlink flash

2026-08-06T00:59:29+00:00

Implement PLDM FW Update in the pds_core driver using the upstream
pldmfw API. This allows updating an entire PLDM FW package at once
or updating specific firmware components by name.

Flash the entire image:
  devlink dev flash pci/0000:b5:00.0 file firmware.pldmfw

Flash a specific component from the PLDM FW package:
  devlink dev flash pci/0000:b5:00.0 \
    file firmware.pldmfw component fw.cpld

Per-component update uses driver-defined component names (fw, fw.cpld,
etc.). Not all components support per-component update - devlink will
reject the request if the specified component cannot be updated.

ethernet: 3c509: Update documentation to match MAINTAINERS

2026-05-21T15:28:56+00:00

There has been apparently a single message only ever publicly posted by
David Ruggiero, back in 2002, which added this documentation piece among
others, and MAINTAINERS was never updated accordingly.  It is therefore
doubtful that his maintainer status has actually come into effect.  Just
replace the reference then so as not to confuse people.

Revert "drivers: net: 3com: 3c509: Remove this driver"

2026-05-21T15:28:56+00:00

This reverts commit 91f3a27ae9f66d81a5906461762c37c8a2bcab06.

Contrary to the assumption stated with the original commit description
this driver is in use and I'm going to maintain it for the foreseeable
future.

net: cs89x0: remove ISA bus probing

2026-05-01T23:46:53+00:00

The cs89x0 driver is really two in one, and they are mutually exclusive:

 - the ISA driver was used on 486-era PCs. It likely has no remaining
   users, like the other ethernet drivers that got removed in
   linux-7.1. The DMA support in here is the last device driver use of
   the deprecated isa_bus_to_virt() interface, all other users are either
   x86 specific or or got converted to the normal dma-mapping interface.
   The driver was maintained by Andrew Morton at the time, based on
   the linux-2.2 vendor driver from Cirrus Logic.

 - the platform_driver instance was used on some embedded Arm boards
   around the same time, such as the EP7211 Development Kit. This
   is the same chip, but uses modern devicetree based probing and no DMA.
   This was added by Alexander Shiyan.

Remove the ISA driver as a cleanup, including all of the outdated
documentation referring to its configuration.

drivers: net: smsc: smc91c92: Remove this driver

2026-04-23T22:57:06+00:00

The smc91c92 was written by David A Hinds in 1999. It is an PCMCIA
device, so unlikely to be used with modern kernels.

Remove the Documentation as well, since it refers to kernel versions
1.2.13 until 1.3.71 and FTP sites which no longer exist.
