This is the final step in making the `zephyr,memory-attr` property
actually useful.
The problem with the current implementation is that `zephyr,memory-attr`
is an enum type, this is making very difficult to use that to actually
describe the memory capabilities. The solution proposed in this PR is to
use the `zephyr,memory-attr` property as an OR-ed bitmask of memory
attributes.
With the change proposed in this PR it is possible in the DeviceTree to
mark the memory regions with a bitmask of attributes by using the
`zephyr,memory-attr` property. This property and the related memory
region can then be retrieved at run-time by leveraging a provided helper
library or the usual DT helpers.
The set of general attributes that can be specified in the property are
defined and explained in
`include/zephyr/dt-bindings/memory-attr/memory-attr.h` (the list can be
extended when needed).
For example, to mark a memory region in the DeviceTree as volatile,
non-cacheable, out-of-order:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_VOLATILE |
DT_MEM_NON_CACHEABLE |
DT_MEM_OOO )>;
};
The `zephyr,memory-attr` property can also be used to set
architecture-specific custom attributes that can be interpreted at run
time. This is leveraged, among other things, to create MPU regions out
of DeviceTree defined memory regions on ARM, for example:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-region = "NOCACHE_REGION";
zephyr,memory-attr = <( DT_ARM_MPU(ATTR_MPU_RAM_NOCACHE) )>;
};
See `include/zephyr/dt-bindings/memory-attr/memory-attr-mpu.h` to see
how an architecture can define its own special memory attributes (in
this case ARM MPU).
The property can also be used to set custom software-specific
attributes. For example we can think of marking a memory region as
available to be used for memory allocation (not yet implemented):
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_NON_CACHEABLE |
DT_MEM_SW_ALLOCATABLE )>;
};
Or maybe we can leverage the property to specify some alignment
requirements for the region:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_CACHEABLE |
DT_MEM_SW_ALIGN(32) )>;
};
The conventional and recommended way to deal and manage with memory
regions marked with attributes is by using the provided `mem-attr`
helper library by enabling `CONFIG_MEM_ATTR` (or by using the usual DT
helpers).
When this option is enabled the list of memory regions and their
attributes are compiled in a user-accessible array and a set of
functions is made available that can be used to query, probe and act on
regions and attributes, see `include/zephyr/mem_mgmt/mem_attr.h`
Note that the `zephyr,memory-attr` property is only a descriptive
property of the capabilities of the associated memory region, but it
does not result in any actual setting for the memory to be set. The
user, code or subsystem willing to use this information to do some work
(for example creating an MPU region out of the property) must use either
the provided `mem-attr` library or the usual DeviceTree helpers to
perform the required work / setting.

This PR makes the modem_pipe instances track if they have
data ready to receive, and invoke the RECEIVE_READY event
every time they are attached if the backend implementing
the pipe has notified that receive is ready.
This mechanism ensures that modules attaching to a pipe
get the async RECEIVE_READY event immediately after
attaching to a pipe if there is data ready, instead of
having to poll the pipe, or worse, wait until newer data
becomes available.
The addition revealed a timing issue in the cmux test
suite. Specifically the CMUX instance now immediately
receives the response to a command which the CMUX
instance has not sent yet, causing it to drop the
response.
The CMUX test suite now uses the transaction
mechanism of the mock_pipe to wait for the command
before sending the response.

Commit 9c5dafed95 ("util: add type checking to CONTAINER_OF") made
`util.h` #include `toolchain/common.h` in order to get `BUILD_ASSERT()`
used by CONTAINER_OF_VALIDATE() when compiling C code.
However `toolchain/common.h` is not supposed to be included directly but
indirectly through `toolchain/<your_toolchain>.h` and in a very specific
order.
The direct inclusion caused the following warning when compiling C++:
```

This commit introduces all the necessary changes for
enabling the usage of shared interrupts.
This works by using a second interrupt table: _shared_sw_isr_table
which keeps track of all of the ISR/arg pairs sharing the same
interrupt line. Whenever a second ISR/arg pair is registered
on the same interrupt line using IRQ_CONNECT(), the entry in
_sw_isr_table will be overwriten by a
(shared_isr, _shared_sw_isr_table[irq]) pair. In turn, shared_isr()
will invoke all of the ISR/arg pairs registered on the same
interrupt line.
This feature only works statically, meaning you can only make use
of shared interrupts using IRQ_CONNECT(). Attempting to dynamically
register a ISR/arg pair will overwrite the hijacked _sw_isr_table
entry.

The current implementation uses both, host and card capabilites to derive
the maximum bus width to be used. However, in cases where a MMC device is
not connected to the host via shdc using the full bus width of 8 lines,
device initialization fails. Introducing the `bus-width` property
circumvents this by reducing the host bus capabilites and forcing
communication with the MMC device using 1, 4 or 8 lines.

When using instance logging (e.g. LOG_INST_INF) first argument is
a pointer to the logging object associated with an instance. It is
not used if logging is disabled and that can generate 'unused
variable' warning when logging is disabled.
Previously logging object was not created when logging was disabled
That was done to save memory but because of that object could not be
referenced when logging was disabled. Better approach is to create
empty array instead of a logging object. It does not increase memory
usage but can be referenced and potential compilation warning is

This commit adds support for partial matches for the modem_chat
module. A match is a combination of an expected response to a
request along with delimiters to use and a handler for the
parsed response.
The usual behavior of the modem_chat script is to continue to
the next step when any expected response is received. The partial
flag indicates that the script should not proceed to the next
step if the response matches the match. This is useful for
commands which respond with an unspecified number of lines,
followed by an "OK". This flag allows the script to essentially
run in a "while" loop until OK is received.
Along with this addition, a more scalable macro for initializing
the modem_chat match struct, MODEM_CHAT_MATCH_INITIALIZER().
Without this macro, we will need 4 different macros to initialize
the 4 variants of a chat_match, and 8 when the next feature is
added...

If ACL is disconnected while read/write is on-going, there is no chance
