Add the Greybus host driver for BeaglePlay board by BeagleBoard.org.
The current greybus setup involves running SVC in a user-space
application (GBridge) and using netlink to communicate with kernel
space. GBridge itself uses wpanusb kernel driver, so the greybus messages
travel from kernel space (gb_netlink) to user-space (GBridge) and then
back to kernel space (wpanusb) before reaching CC1352.
This driver directly communicates with CC1352 (running SVC Zephyr
application). Thus, it simplifies the complete greybus setup eliminating
user-space GBridge.
This driver is responsible for the following:
- Start SVC (CC1352) on driver load.
- Send/Receive Greybus messages to/from CC1352 using HDLC over UART.
- Print Logs from CC1352.
- Stop SVC (CC1352) on driver load.

This reverts commit 517f14d9cf.
Config option "no_of_node" is no longer needed since adding a more
explicit and targeted option "add_legacy_fixed_of_cells".
That "no_of_node" config option was needed *earlier* to help mtd's case.
DT nodes of MTD partitions (that are also NVMEM devices) may contain
subnodes. Those SHOULD NOT be treated as NVMEM fixed cells.
To prevent NVMEM core code from parsing subnodes a "no_of_node" option
was added (and set to true in mtd) to make for_each_child_of_node() in
NVMEM a no-op. That was a bit hacky because it was messing with
"of_node" pointer to achieve some side-effect.
With the introduction of "add_legacy_fixed_of_cells" config option
things got more explicit. MTD subsystem simply tells NVMEM when to look
for fixed cells and there is no need to hack "of_node" pointer anymore.

Binding for fixed NVMEM cells defined directly as NVMEM device subnodes
has been deprecated. It has been replaced by the "fixed-layout" NVMEM
layout binding.
New syntax is meant to be clearer and should help avoiding imprecise
bindings.
NVMEM subsystem already supports the new binding. It should be a good
idea to limit support for old syntax to existing drivers that actually
support & use it (we can't break backward compatibility!). That way we
additionally encourage new bindings & drivers to ignore deprecated
binding.
It wasn't clear (to me) if rtc and w1 code actually uses old syntax
fixed cells. I enabled them to don't risk any breakage.

IIO: 1st set of new device support, features and cleanup for 6.7
Particularly great to see a resolver driver move out of staging via a
massive set of changes. Only took 13 years :)
One small patch added then reverted due to a report of test breakage
(ashai-kasei,ak8975: Drop deprecated enums.)
An immutable branch was used for some hid-senors changes in case
there was a need to take them into the HID tree as well.
New device support
-----------------
adi,hmc425a
- Add support for HMC540SLP3E broadband 4-bit digital attenuator.
kionix,kx022a
- Add support for the kx132-1211 accelerometer. Require significant
driver rework to enable this including add a chip type specific
structure to deal with the chip differences.
- Add support for the kx132acr-lbz accelerometer (subset of the kx022a
feature set).
lltc,ltc2309
- New driver for this 8 channel ADC.
microchip,mcp3911
- Add support for rest of mcp391x family of ADCs (there are various
differences beyond simple channel count variation.
Series includes some general driver cleanup.
microchip,mcp3564
- New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564
and their R variants of 16/24bit ADCs. A few minor fixed followed.
rohm,bu1390
- New driver for this pressure sensor.
Staging graduation
------------------
adi,ad1210 (after 13 or so years :)
- More or less a complete (step-wise) rewrite of this resolver driver
to bring it up to date with modern IIO standards. The fault signal
handling mapping to event channels was particularly complex and
significant part of the changes.
Features
--------
iio-core
- Add chromacity and color temperature channel types.
adi,ad7192
- Oversampling ratio control (called fast settling in datasheet).
adi,adis16475
- Add core support and then driver support for delta angle and delta
velocity channels. These are intended for summation to establish
angle and velocity changes over larger timescales. Fix was
needed for alignment after the temperature channel. Further fix
reduced set of devices for which the buffer support was applicable
as seems burst reads don't cover these on all devices.
hid-sensors-als
- Chromacity and color temperatures support including in amd sfh.
stx104
- Add support for counter subsystem to this multipurpose device.
ti,twl6030
- Add missing device tree binding description.
Clean up and minor fixes.
------------------------
treewide
- Drop some unused declarations across IIO.
- Make more use of device_get_match_data() instead of OF specific
approaches.
Similar cleanup to sets of drivers.
- Stop platform remove callbacks returning anything by using the
temporary remove_new() callback.
- Use i2c_get_match_data() to cope nicely with all types of ID table
entry.
- Use device_get_match_data() for various platform device to cope
with more types of firmware.
- Convert from enum to pointer in ID tables allowing use of
i2c_get_match_data().
- Fix sorting on some ID tables.
- Include specific string helper headers rather than simply string_helpers.h
docs
- Better description of the ordering requirements etc for
available_scan_masks.
tools
- Handle alignment of mixed sizes where the last element isn't the biggest
correctly. Seems that doesn't happen often!
adi,ad2s1210
- Lots of work from David Lechner on this driver including a few fixes
that are going with the rework to avoid slowing that down.
adi,ad4310
- Replace deprecated devm_clk_register()
adi,ad74413r
- Bring the channel function setting inline with the datasheet.
adi,ad7192
- Change to FIELD_PREP(), FIELD_GET().
- Calculate f_order from the sinc filter and chop filter states.
- Move more per chip config into data in struct ad7192_chip_info
- Cleanup unused parameter in channel macros.
adi,adf4350
- Make use of devm_* to simplify error handling for many of the setup
calls in probe() / tear down in remove() and error paths. Some more
work to be done on this one.
- Use dev_err_probe() for errors in probe() callback.
adi,adf4413
- Typo in function name prefix.
adi,adxl345
- Add channel scale to the chip type specific structure and drop
using a type field previously used for indirection.
asahi,ak8985
- Fix a mismatch introduced when switching from enum->pointers
in the match tables.
amlogic,meson
- Expand error logging during probe.
invensense,mpu6050
- Support level-shifter control. Whilst no one is sure exactly what this
is doing it is needed for some old boards.
- Document mount-matrix dt-binding.
mediatek,mt6577
- Use devm_clk_get_enabled() to replace open coded version and move
everything over to being device managed. Drop now empty remove()
callback. Fix follows to put the drvdata back.
- Use dev_err_probe() for error reporting in probe() callback.
memsic,mxc4005
- Add of_match_table.
microchip,mcp4725
- Move various chip specific data from being looked up by chip ID to
data in the chip type specific structure.
silicon-labs,si7005
- Add of_match_table and entry in trivial-devices.yaml
st,lsm6dsx
- Add missing mount-matrix dt binding documentation.
st,spear
- Use devm_clk_get_enabled() and some other devm calls to move everything
over to being device managed. Drop now empty remove() callback.
- Use dev_err_probe() to better handled deferred probing and tidy up
error reporting in probe() callback.
st,stm32-adc
- Add a bit of additional checking in probe() to protect against a NULL
pointer (no known path to trigger it today).
- Replace deprecated strncpy()
ti,ads1015
- Allow for edge triggers.
- Document interrupt in dt-bindings.

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() will be renamed to .remove().
Several drivers use qcom_icc_rpmh_remove() as remove callback which
returns zero unconditionally. Make it return void and use .remove_new in
the drivers. There is no change in behaviour.

GSC devices perform legal firmware initiated resets due to state transition
that may appear as unexpected to the driver. Lower the log level for those
devices to debug level and save the firmware status registers.
When the device comes out of the reset it is possible to check whether the
resets was due to a firmware error or an exception
and only than produce a warning.
