71d41c09f1 batman-adv: Move IRC channel to hackint.org
Due to recent developments around the Freenode.org IRC network, the
opinions about the usage of this service shifted dramatically. The majority
of the still active users of the #batman channel prefers a move to the
hackint.org network.

1081b9d971 iio: chemical: Add driver support for sgp40
sgp40 is a gas sensor used for measuring the air quality.

This driver is reading the raw resistance value which can be passed to
an userspace algorithm for further calculation.

The raw value is also used to calculate an estimated absolute voc index
in the range from 0 to 500. For this purpose the raw_mean value of the
resistance for which the index value is 250 might be set up as a
calibration step. This can be done with in_resistance_calibbias.

Compensation of relative humidity and temperature is supported and can
be used by writing to output values of out_humidityrelative_raw and
out_temp_raw.

There is a predecesor sensor type (sgp30) already existing. This driver
module was not extended because the new sensor is quite different in its
i2c telegrams.

56e7a93160 ASoC: Fixes for v5.14
Quite a lot of fixes here, the biggest set being for the cs42l42 driver
 which is reasonably old but has seen a sudden uptick in activity.
 There's also some fixes for correctly referencing PCM buffer addresses
 and the removal of some driver-local bodges that had been done for the
 lack of prefix handling in DAPM which were broken by the core handling
 that as expected.

d249ff28b1 intersil: remove obsolete prism54 wireless driver
Commit 1d89cae1b47d ("MAINTAINERS: mark prism54 obsolete") indicated the
prism54 driver as obsolete in July 2010.

Now, after being exposed for ten years to refactoring, general tree-wide
changes and various janitor clean-up, it is really time to delete the
driver for good.

This was discovered as part of a checkpatch evaluation, investigating all
reports of checkpatch's WARNING:OBSOLETE check.

p54 replaces prism54 so users should be unaffected. There was a one off chipset
someone long ago reported that p54 didn't work with but the reporter never
followed up on that. Additionally, distributions have been blacklisting prism54
for years now.

e50abb3aa5 MAINTAINERS: update STAGING - REALTEK RTL8188EU DRIVERS
Commit 55dfa29b43d2 ("staging: rtl8188eu: remove rtl8188eu driver from
staging dir") removes ./drivers/staging/rtl8188eu, but misses to adjust
the STAGING - REALTEK RTL8188EU DRIVERS section in MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains:

  no file matches    F:    drivers/staging/rtl8188eu/

A refurnished rtl8188eu driver is available in ./drivers/staging/r8188eu/
and there is no existing section in MAINTAINERS for that directory.

So, reuse the STAGING - REALTEK RTL8188EU DRIVERS section and point to the
refurnished driver with its current developers and maintainers according
to the current git log.

46abe13b5e firmware: arm_scmi: Add virtio transport
This transport enables communications with an SCMI platform through virtio;
the SCMI platform will be represented by a virtio device.

Implement an SCMI virtio driver according to the virtio SCMI device spec
[1]. Virtio device id 32 has been reserved for the SCMI device [2].

The virtio transport has one Tx channel (virtio cmdq, A2P channel) and
at most one Rx channel (virtio eventq, P2A channel).

The following feature bit defined in [1] is not implemented:
VIRTIO_SCMI_F_SHARED_MEMORY.

The number of messages which can be pending simultaneously is restricted
according to the virtqueue capacity negotiated at probing time.

As soon as Rx channel message buffers are allocated or have been read
out by the arm-scmi driver, feed them back to the virtio device.

Since some virtio devices may not have the short response time exhibited
by SCMI platforms using other transports, set a generous response
timeout.

SCMI polling mode is not supported by this virtio transport since deemed
meaningless: polling mode operation is offered by the SCMI core to those
transports that could not provide a completion interrupt on the TX path,
which is never the case for virtio whose core callbacks can easily call
into core scmi_rx_callback upon messages reception.

hyperv-tlfs.h defines Hyper-V interfaces from the Hyper-V Top Level
Functional Spec (TLFS), and #includes the architecture-independent
part of hyperv-tlfs.h in include/asm-generic.  The published TLFS
is distinctly oriented to x86/x64, so the ARM64-specific
hyperv-tlfs.h includes information for ARM64 that is not yet formally
published. The TLFS is available here:

  docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/tlfs

mshyperv.h defines Linux-specific structures and routines for
interacting with Hyper-V on ARM64, and #includes the architecture-
independent part of mshyperv.h in include/asm-generic.

Use these definitions to provide utility functions to make
Hyper-V hypercalls and to get and set Hyper-V provided
registers associated with a virtual processor.

1c953bda90 bus: ixp4xx: Add a driver for IXP4xx expansion bus
The Intel IXP4xx SoCs have an expansion bus that is usually just
used for flash memory and configured by the boot loaders and can
be accessed using the "simple-bus".

However some devices need more elaborate configuration and then we
need to provide a proper 3-unit address space indicating chip
select for each device and provide timing and similar information.

ced75a2f5d MAINTAINERS: Add Luis Chamberlain as modules maintainer
Luis has kindly agreed to help maintain the module loader. As my
responsibilities have shifted, I've found myself with less cycles to
devote to upstream maintenance these days. Luis is already very involved
and engaged upstream, and with his experience maintaining the kmod
module loader and usermode helper, I believe he is a great fit for this
area of the kernel.

pull-request: can 2021-07-30

The first patch is by me and adds Yasushi SHOJI as a reviewer for the
Microchip CAN BUS Analyzer Tool driver.

Dan Carpenter's patch fixes a signedness bug in the hi311x driver.

Pavel Skripkin provides 4 patches, the first targets the mcba_usb
driver by adding the missing urb->transfer_dma initialization, which
was broken in a previous commit. The last 3 patches fix a memory leak
in the usb_8dev, ems_usb and esd_usb2 driver.

Commit 9bd9e0de1cf5 ("mfd: hi6421-spmi-pmic: move driver from staging")
moves the last driver out of ./drivers/staging/hikey9xx/ and removes that
directory, but missed to adjust the HISILICON STAGING DRIVERS FOR HIKEY
960/970 section in MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains:

  warning: no file matches    F:    drivers/staging/hikey9xx/

As the directory ./drivers/staging/hikey9xx/ is gone, remove the section
