MHI Host
========
Core
----
- Skipped MHI reset if the device is in RDDM EE (Ramdump mode) since the device
cannot process reset request.
- Updated the sysfs contact details to use MHI list instead of bouncing
codeaurora email ids.
- Added support to allow MHI client drivers to provide the device firmware via
a pointer. This is required to support new firmware format to be used by
ath11k drivers.
- Used vcalloc instead of vzalloc to protect against multiplication overflows.
- Removed decrementing one unused parameter.
pci_generic
-----------
- Added support for MHI SW channels (IP_SW0) so that the host can transfer data
from devices over networking interface through this specific channel.
- Added support for a clone of Quectel RM520N-GL modem which uses a different
PID as it is targeted for laptop usecase.
- Added support for a clone of Quectel EM160R-GL modem which uses a different
PID as it is targeted for laptop usecase.
- Added support for another clone of Quectel RM520N-GL modem which uses a
different PID as it is targeted for Lenovo laptop usecase.
- Added support for Dell DW5932e modem (both eSIM and non-eSIM variants).
- Added support for Telit FE990 modem.

1st set of IIO new device support, features and cleanup for 6.6
New device support
* adi,ad8366
- Add support for the HMC792 digital attenuator (mostly chip specific data)
* alwinner,sun20i-gpadc
- New driver for the integrated ADC on a number of allwinner SoCs
including dt-binding documentation.
* microchip,mcp4728
- New driver for this quad channel DAC. Includes dt-bindings.
* miramems, da280
- Add ID for DA217 accelerometer which is compatible with the da280.
* murata,irs-d200
- New driver for this passive infrared sensor typically used for human
detection. Includes bindings and a few pieces of new ABI to
cover a case of needing to count a number of repeats of an event
before reporting it.
* rohm,bu27008
- Add initial support for the BU27010 RGB + flickering sensor to this
driver. Substantial refactoring was needed to enable this.
Features
* adi,admv8818
- Add mode that bypasses the input and output filters.
* amlogic,meson
- Support control of the MUX on channel 7, exposed as multiple channels.
- Support channel labels.

to consistently assume no positive return values.
- Use min() rather than min_t() in a case where types were clearly
the same.
- Drop some else statements that follow continue with a loop or
a returns.

of structures, not just one.
* tools

* tree wide
- Fix up includes for DT related headers.
- Drop some error prints in places where as similar error message

for other Allwinner devices.

MUX.

tables.

drivers: iio: filter: admv8818: add bypass mode
Add filter bypass mode, which bypasses the low pass filter, high pass
filter and disables/unregister the clock rate notifier.
Currently a feature like bypassing the filter is not achievable
straightforward and not very deductive. The user has to look through the
code and call the set_lpf_3db_frequency and set_hpf_3db_frequency iio
attributes from the user interface using the corner cases (freq >
largest lpf supported by the part, respectively freq < smallest hpf
supported by the part). Moreover, in such case of bypassing the filter,
the input clock rate change might mess up things so we want to make sure
that it is disabled. Also, the feature will help emphasizing the filter
behavior, therefore adding it in the userspace will ease the
charcaterization of the filter's effects when active/disabled.
It was requested by users of the driver to ease the interaction with
different configuration modes of the device.

iio: light: bd27008: Support BD27010 RGB
The ROHM BU27010 is an RGBC sensor with a flickering detection FIFO. The
RGBC+IR sensor functionality is largely similar to what the BU27008 has.
There are some notable things though:
- gain setting is once again new and exotic. Now, there is 6bit gain
setting where 4 of the bits are common to all channels and 2 bits
can be configured separately for each channel. The BU27010 has
similar "1X on other channels vs 2X on IR when selector is 0x0"
gain design as BU27008 had. So, we use same gain setting policy for
BU27010 as we did for BU27008 - driver sets same gain selector for all
channels but shows the gains separately for all channels so users
can (at least in theory) detect this 1X vs 2X madness...
- BU27010 has suffled all the control register bitfields to new
addresses and bit positions while still keeping the register naming
same.
- Some more power/reset control is added.
- FIFO for "flickering detection" is added.
The control register suffling made this slightly nasty. Still, it is
easier for maintenance perspective to add the BU27010 support in BU27008
driver because - even though the bit positions/addresses were changed -
most of the driver structure can be re-used. Writing own driver for
BU27010 would mean plenty of duplicate code albeit a tad more clarity.
The flickering FIFO is not supported by the driver.
Add BU27010 RGBC+IR support to rohm-bu27008 driver.

misc: tps6594-esm: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
There are two calls that can go wrong in tps6594_esm_remove(); for both
there is already an error message. Not returning the error code has the
only side effect of suppressing (another) error message by the core
about the error being ignored. So tps6594_esm_remove() can be converted
to return void without any loss.

iio: cdc: ad7150: relax return value check for IRQ get
fwnode_irq_get[_byname]() were changed to not return 0 anymore. The
special error case where device-tree based IRQ mapping fails can't no
longer be reliably detected from this return value. This yields a
functional change in the driver where the mapping failure is treated as
an error.
The mapping failure can occur for example when the device-tree IRQ
information translation call-back(s) (xlate) fail, IRQ domain is not
found, IRQ type conflicts, etc. In most cases this indicates an error in
the device-tree and special handling is not really required.
One more thing to note is that ACPI APIs do not return zero for any
failures so this special handling did only apply on device-tree based
systems.
Drop the special handling for DT mapping failures as these can no longer
be separated from other errors at driver side. Change all failures in
IRQ getting to be handled by continuing without the events instead of
aborting the probe upon certain errors.

char: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

If a resize shrinks the buffer it clears the read count to notify
readers that they need to reset. But the read count is also used for
accounting and this causes the numbers to be off. Instead, create a
separate variable to use to notify readers to reset.

place when the SOFT_MODE is set or cleared.
