fc68d26e9c doc: hardware: peripherals: mipi_dbi: Added a newline to fix a typo
Added a newline to display the list correctly

The list is displayed like:
MIPI DBI defines 3 interface types: * Type A: Motorola 6800 parallel bus
 * Type B: Intel 8080 parallel bus

But it should be like:
MIPI DBI defines 3 interface types:
 * Type A: Motorola 6800 parallel bus
 * Type B: Intel 8080 parallel bus

This was fixed by an example from another doc:

a57db0ddcb drivers: can: rework support for manual bus-off recovery
Since all CAN controllers drivers seem to support automatic recovery (for
any future drivers for hardware without this hardware capability this can
easily be implemented in the driver), change the Zephyr CAN controller API
policy to:

- Always enable automatic bus recovery upon driver initialization,
  regardless of Kconfig options. Since CAN controllers are initialized in
  "stopped" state, no unwanted bus-off recovery will be started at this
  point.

- Invert and rename the Kconfig CONFIG_CAN_AUTO_BUS_OFF_RECOVERY, which is
  enabled by default, to CONFIG_CAN_MANUAL_RECOVERY_MODE, which is disabled
  by default. Enabling CONFIG_CAN_MANUAL_RECOVERY_MODE=y enables support
  for the can_recover() API function and a new manual recovery mode (see
  next bullet). Keeping this guarded by Kconfig allows keeping the flash
  footprint down for applications not using manual bus-off recovery.

- Introduce a new CAN controller operational mode
  CAN_MODE_MANUAL_RECOVERY. Support for this is only enabled if
  CONFIG_CAN_MANUAL_RECOVERY_MODE=y. Having this as a mode allows
  applications to inquire whether the CAN controller supports manual
  recovery mode via the can_get_capabilities() API function and either fail
  or rely on automatic recovery - and it allows CAN controller drivers not
  supporting manual recovery mode to fail early in can_set_mode() during
  application startup instead of failing when can_recover() is called at a
  later point in time.

3436c93387 drivers: can: remove run-time RTR filtering, add build-time RTR filter
A growing number of CAN controllers do not have support for individual RX
hardware filters based on the Remote Transmission Request (RTR) bit. This
leads to various work-arounds on the driver level mixing hardware and
software filtering.

As the use of RTR frames is discouraged by CAN in Automation (CiA) - and
not even supported by newer standards, e.g. CAN FD - this often leads to
unnecessary overhead, added complexity, and worst-case to non-portable
behavior between various CAN controller drivers.

Instead, move to a simpler approach where the ability to accept/reject RTR
frames is globally configured via Kconfig. By default, all incoming RTR
frames are rejected at the driver level, a setting which can be supported
in hardware by most in-tree CAN controllers drivers.

Legacy applications or protocol implementations, where RTR reception is
required, can now select CONFIG_CAN_ACCEPT_RTR to accept incoming RTR
frames matching added CAN filters. These applications or protocols will
need to distinguish between RTR and data frames in their respective CAN RX
frame handling routines.

344d24bcb7 docs: Better document the DMA API and expectations
The DMA API has several expectations for drivers and callers that were
underdocumented or undocumented. Better clarify the driver expectations
and caller expectations.

The DMA API from the caller side is not a portable API and really cannot
be as each DMA has unique properties and expectations of memory,
peripheral interaction, and features. The API in effect provides a union
of all useful DMA functionality drivers have needed in the tree. It can
still be a good abstraction, with care, for peripheral devices for
vendors where the DMA IP might be very similar but have slight
variances.

From the driver implementation side expectations around synchronization,
state transitions, and memory management for transfer descriptors is now
described in documentation rather than solely from me in github review
comments.

e294b16a2f fuel_gauge: Add fuel_guage_get_props()
The fuel_gauge_get_prop() function prototype declares a function that
retrieves multiple fuel gauge properties at once. The naming suggests it
ought to fetch a singular property at a time. Moreso, some clients may just
want to fetch properties one at a time and may feel uncomfortable using a
prototype for fetching multiple properties when wanting to fetch them one
at a time.

Modify fuel_gauge_get_prop() to fetch a single property and add
fuel_gauge_get_props() to support fetching multiple properties. Modify
existing tests/drivers/samples.

This is part of #61818 work.

properties are readable or writable. This lead to duplication in property
names and potential confusion for new users of the API. See issue #61818.

supported for read or write actions.

171c1fc9d9 emul: Introduce emulator backend API and generic sensor test
This PR introduces a backend API to be implemented by sensor emulators
that creates a standardized mechanism for setting expected sensor
readings in tests. This unlocks the ability to create a generic sensor
test that can automatically set expected values in supported sensor
emulators and verify them through the existing sensor API. An
implementation of this API is provided for the AKM09918C magnetometer.

A generic sensor test is also created to exercise this implementation.
Observe that this test knows nothing about the AKM09918C; info about
supported channels and sample ranges is discovered through the backend
API. The test iterates over all devices attached to the virtual I2C and
SPI buses in the test binary's device tree, which (theoretically) covers
all sensors. Sensors whose emulator does not exist yet or does not
support the backend API are skipped.

9f02eeadf8 serial: allow callback setting to be exclusive
Both the IRQ API and Asynchronous API support callback.
However, since they are both interrupt driven, having
callbacks on both API would interfere with each other
in almost all cases. So this adds a kconfig to signal
that the callbacks should be exclusive to each other.
In other words, if one is set, the other should not
be active. Drivers implementing both APIs have been
updated to remove the callbacks from the other API.
Though, this still leaves the option to disable
the kconfig and allows both APIs to have callbacks
if one desires.
