While the driver is still marked as maintained in MAINTAINERS, Comtrol
does not really care about this ancient driver. They are still
manufacturing serial devices, but those are controlled only by
out-of-tree drivers.
Comtrol didn't answer my pings, so this driver is apparently
unmaintained. Aside from that, the driver was untouched for years, only
whole-tree changes happened during the past years. The driver needs much
more care, so drop it for now. If someone steps up to reintroduce it,
they need to clean it up first.

The Cyclades driver was orphaned by commit d459883e6c54 (MAINTAINERS:
remove two dead e-mail) 13 years ago. Noone stepped up to take care of
them and to fix all the issues the driver has.
On the top of that, there is no way to obtain the firmware for Z cards
from the vendor as cyclades.com ceased to exist.
So it's time to drop the driver with all its traces.

The drivers were removed in a1f714b44e34 (tty: Remove redundant synclink
driver) and 3d608a591b2b (tty: Remove redundant synclinkmp driver).
So remove also the PCI ID entries.

The CXL.mem protocol allows a device to act as a provider of "System
RAM" and/or "Persistent Memory" that is fully coherent as if the memory
was attached to the typical CPU memory controller.
With the CXL-2.0 specification a PCI endpoint can implement a "Type-3"
device interface and give the operating system control over "Host
Managed Device Memory". See section 2.3 Type 3 CXL Device.
The memory range exported by the device may optionally be described by
the platform firmware memory map, or by infrastructure like LIBNVDIMM to
provision persistent memory capacity from one, or more, CXL.mem devices.
A pre-requisite for Linux-managed memory-capacity provisioning is this
cxl_mem driver that can speak the mailbox protocol defined in section
8.2.8.4 Mailbox Registers.
For now just land the initial driver boiler-plate and Documentation/
infrastructure.

If a Root Complex Integrated Endpoint (RCiEP) is implemented, it may signal
errors through a Root Complex Event Collector (RCEC). Each RCiEP must be
associated with no more than one RCEC.
For an RCEC (which is technically not a Bridge), error messages "received"
from associated RCiEPs must be enabled for "transmission" in order to cause
a System Error via the Root Control register or (when the Advanced Error
Reporting Capability is present) reporting via the Root Error Command
register and logging in the Root Error Status register and Error Source
Identification register.
Given the commonality with Root Ports and the need to also support AER and
PME services for RCECs, extend the Root Port driver to support RCEC devices
by adding the RCEC Class ID to the driver structure.

Pull sound updates from Takashi Iwai:
"As shown in diffstat and logs, it was again a busy development cycle
at this time, too. The most significant changes are still on-going
refactoring / modernization works for ASoC core and drivers, but there
are lots of other changes as well. Here we go, some highlights below:
ASoC:
- Quite a lot of cleanup / refactoring of ASoC core and APIs; most of
them are systematic, but also including cleanups and modernization
- A bulk of updates for some ASoC platforms, Freescale, sunxi and
Intel SST/SOF
- Initial support for Sound Open Firmware on i.MX8
- Removal of deprecated w90x900 and nuc900 drivers
- New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
7ULP and 8MQ, Meson G12A and NXP UDA1334
USB-audio:
- More validations of descriptor units for hardening against bugs
reported by fuzzers
- PCM device assignment workaround for a past call-order change
- Scarlett Gen2 mixer interface, a few more more quirks
HD-audio:
- Support for audio component with AMD/ATI and Nvidia HDMI codecs
- Clean up HD-audio core and remove indirect access ops for Intel SOF
- DMIC detection at probe; it would make systems automatically
falling back to SST/SOF driver on devices that need DMIC handling.
Needs a new Kconfig to set, and beware that it's still new and a
bit experimental
FireWire:
- Lots of code refactoring and cleanups"

The AMD Ryzen gen 3 processors came with a different PCI IDs for the
function 3 & 4 which are used to access the SMN interface. The root
PCI address however remained at the same address as the model 30h.
Adding the F3/F4 PCI IDs respectively to the misc and link ids appear
to be sufficient for k10temp, so let's add them and follow up on the
patch if other functions need more tweaking.
Vicki Pfau sent an identical patch after I checked that no-one had
written this patch. I would have been happy about dropping my patch but
unlike for his patch series, I had already Cc:ed the x86 people and
they already reviewed the changes. Since Vicki has not answered to
any email after his initial series, let's assume she is on vacation
and let's avoid duplication of reviews from the maintainers and merge
my series. To acknowledge Vicki's anteriority, I added her S-o-b to
the patch.

* pci/trivial:
PCI: Fix typos and whitespace errors
|

Many NVIDIA GPUs can be configured as either a single-function video device
or a multi-function device with video at function 0 and an HDA audio
controller at function 1. The HDA controller can be enabled or disabled by
a bit in the function 0 config space.
Some BIOSes leave the HDA disabled, which means the HDMI connector from the
NVIDIA GPU may not work. Sometimes the BIOS enables the HDA if an HDMI
cable is connected at boot time, but that doesn't handle hotplug cases.
Enable the HDA controller on device enumeration and resume and re-read the
header type, which tells us whether the GPU is a multi-function device.
This quirk is limited to NVIDIA PCI devices with the VGA Controller device
class. This is expected to correspond to product configurations where the
NVIDIA GPU has connectors attached. Other products where the device class
is 3D Controller are expected to correspond to configurations where the
NVIDIA GPU is dedicated (dGPU) and has no connectors. See original post
(URL below) for more details.
This commit takes inspiration from an earlier patch by Daniel Drake.

Pull x86 cpu updates from Ingo Molnar:
"The main changes in this cycle were:
- Add support for the "Dhyana" x86 CPUs by Hygon: these are licensed
based on the AMD Zen architecture, and are built and sold in China,
for domestic datacenter use. The code is pretty close to AMD
support, mostly with a few quirks and enumeration differences. (Pu
Wen)
- Enable CPUID support on Cyrix 6x86/6x86L processors"

Hygon's PCI vendor ID is 0x1d94, and there are PCI devices
0x1450/0x1463/0x1464 for the host bridge on the Hygon Dhyana platform.
Add Hygon Dhyana support to the PCI and northbridge subsystems by using
the code path of AMD family 17h.
[ bp: Massage commit message, sort local vars into reverse xmas tree
order and move the amd_northbridges.num check up. ]
