Thomas Stranger e53ee41338 driver: dmamux: use LL_DMAMUX_CHANNEL_X flag to check if channels exists
Use LL_DMAMUX_CHANNEL_x defines instead of DMAMUX_CSR_SOF7x to check
if corresponding LL_DMAMUX_IsActiveFlag_SOx and LL_DMAMUX_ClearFlag_SOx
inline functions exist and should be added to func_ll_is_active_so[]
and func_ll_clear_so[].
The HAL of some socs uses the same flag to decide which registers exist
on a specific soc. And the same defines are used for table_ll_channel[]
initializations.

This is necessary because DMAMUX_CSR_SOF5 and DMAMUX_CSR_SOF6 were
wrongly added in the HALs soc header file for some stm32g0 socs,
therefore without this change some stm32g0 socs couldn't compile.

Thomas Stranger 5a475d7cc2 drivers/dma: stm32: add support for stm32g0 series
Update the existing driver to support STM32G0 series.
It enables the DMA_STM32_SHARED_IRQS flag for g0 series, such that
all interrupts are handled in a shared isr to avoid irq conflicts.
The shared isr is extended to be able to handle irqs from more than one
dma instance.

Furthermore the config_irq function of instance 1, which connects to the
irqs, was reworked to avoid irq conflicts when 2 dma instances on
stm32f0, or stm32g0 are enabled:
While dma1 has one exclusive irq for channel 1, and one irq for dma1
channels 2 and 3, all other channels share the same irq.
Therefore it is currently not possible to enable dma2 without enabling
dma1 at the same time, without getting an build errror due to an irq
conflict.

Thomas Stranger 73374fbfa9 driver: dmamux: enable clocks only if node has clocks property defined
Not all STM32 Series can enable a dedicated clock for dmamux.
In stm32g0 series for example the clock is enabled automatically
as long as either DMA1 or DMA2 is enabled.
This commit changes dmamux driver to cope with socs that don't have
defined a clocks property. Therefore it moves the config(and data)
struct into the c file to be able to use DT_INST_NODE_HAS_PROP macro.

Shlomi Vaknin 23bb30a73a stm32: dmamux: change initialization order to PRE_KERNEL_1
When running the tests of the async api of uart
on nucleo-l4r5zi we get MPU fault.
The reason is ordering initialization. The uart and dma
drivers are initialized PRE_KERNEL_1 while dmamux is
initialized POST_KERNEL.
Thus, the function device_get_binding fails since the
dmamux device is not ready to be used.

Fixes: #32715.

Move dmamux_stm32_channels struct from device data to device
configuration and initialize the dmamux channel - dma channel
assignment during build time,
as this association is hardwired in all known series.
The information is taken from dma_offset and dma_requests device tree
properties. The current implementation is valid for series with either
a single or two dma peripherals and a single dmamux peripheral.
Both dmas can independently enabled.
As the driver uses multi-instance DT_INST_DEFINE, also macros for a
second dmamux are are added that should allow easier extension to a
second dmamux instance.

Erwin Rol 113b016b51 drivers: dma: stm32: change order of disabling and checking result
The stm32_dma_disable_stream first checked if the stream was
disabled and if so returned OK. If it wasn't disabled it
tried to disable it and returned -EAGAIN.

The function is used in loops that try to disable the stream
by calling this function and if it fails wait for 1ms and
retry.

Becuase this function the first time (if the stream wasn't
disabled already) fails there is always a 1 ms delay. For
the SPI driver, that has a RX and TX stream, this means
a 2ms delay between the last data and CS going high.

By first trying to disable the stream and than checking
if it succeded most of the time the first call disables
the stream and the 1ms delay isn't needed.

Martí Bolívar 6e8775ff84 devicetree: remove DT_HAS_NODE_STATUS_OKAY
Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:

- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
  for macros which are equivalent to
  DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name

Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.

This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Martí Bolívar 7e0eed9235 devicetree: allow access to all nodes
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.

Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.

To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:

- emit macros for all existing nodes in gen_defines.py, regardless
  of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

Martí Bolívar 87e1743ae0 devicetree: replace DT_HAS_DRV_INST with DT_INST_FOREACH
Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.

There are a few exceptions:

- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
  would require more time to convert than I have at the moment. For the
  sake of expediency, just inline the DT_HAS_DRV_INST expansion for
  now in these cases.

- SoC drivers which are explicitly single-instance (like the nRF SAADC
  driver). Again for the sake of expediency, drop a BUILD_ASSERT in
  those cases to make sure the assumption that all supported SoCs have
  at most one available instance is valid, failing fast otherwise.

Stephanos Ioannidis 2a710b1372 Revert "drivers: dma: sam0: fix DMA to peripheral transfer on SAMD5x"
This reverts commit 90cc723e65.

Using `DMAC_CHCTRLA_TRIGACT_BLOCK` breaks SERCOM UART peripheral DMA
operations (DMA-based asynchronous UART transmit operation only sends
the first byte and does not proceed any further).

The `DMAC_CHCTRLA_TRIGACT_BURST` with `DMAC_CHCTRLA_BURSTLEN(0)` is a
special case utilising the "internal FIFO", according to the datasheet
(see DS60001507E; 22.6.2.8), and should always be specified for
peripheral data transfer operations.

Also it is worth noting that Atmel and other third-party drivers use
the aforementioned "internal FIFO" configuration for peripheral data
transfers as well.

the memory-to-memory transfers. For DMA Version1,
in the stm32f2xx, stm32f4xx, stm32f7xx series,
only DMA instance 2 is able to transfer mem-to-mem.
For other series, with DMA Version2, there is no such a limitation.

Song Qiang 40962a81e7 drivers: dma: stm32: add missing fifo operation
The DMA driver of stm32 used to use `stm32_dma_enable_fifo()`,
which is located in dma_stm32_v1.c to set DMDIS bit, enable
interrupt generation and set FIFO threshold. Now since FIFO
threshold is initialized with `stm32_dma_get_fifo_threshold()`
and interrupt generation is also configured in dma_stm32.c, this
function will only have one job, to configure FIFO mode.
We can add FIFO mode operation in dma_stm32.c directly and
remove it from dma_stm32_v1.c.

Song Qiang 749d2d21bf drivers: dma: add generic driver support for some series of stm32
This commit adds driver support for DMA on f0/f1/f2/f3/f4/l0/l4
series stm32.

Notice due to some bugs, this is currently not working with f7.

There are two kinds of IP blocks are used across these stm32, one is the
one that has been used on F2/F4/F7 series, and the other one is the one
that has been used on F0/F1/F3/L0/L4 series.

Memory to memory transfer is only supported on the second DMA on
F2/F4 with 'st,mem2mem' to be declared in dts.

This driver depends on k_malloc to allocate memory for stream instances,
so CONFIG_HEAP_MEM_POOL_SIZE must be big enough to hold them.

Common parts of the driver are in dma_stm32.c and SoC related parts are
implemented in dma_stm32_v*.c.

This driver has been tested on multiple nucleo boards, including
NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/L073RZ/L476RG with the
loop_transfer and chan_blen_transfer test cases.

Ulf Magnusson 975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Ulf Magnusson 677f1e6db9 kconfig: Turn pointless/confusing 'menuconfig's into 'config's
Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.

Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.

    [*] Enable foo ---

This is how it would be shown if there were children but they all
happened to be invisible as well.

With a regular 'config', it turns into

    [*] Enable foo

Change all pointless 'menuconfig's to 'config's.

See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

Jun Li 74e320d859 api: dma: add api to retrieve runtime status
Some applications using DMA, such as UART RX, could
need to complete the current DMA transaction earlier than
predefined, based on other termination conditions,
like UART's IDLE interrupts.

In that case, the client needs to know how many data are
still left in DMA transfer buffer so that it can figure
out how many data has been transfered. However, the current
DMA API doesn't provide any information for the client
to learn the transfer buffer information.

And some other information, like whether DMA transfer is busy
or not, transfer direction, etc, could interest a client.

So, added a dma API function to retrieve the current DMA
runtime status.

And implemented the API for STM32F4's DMA while keeping
others unimplemented.

To support async mode, a new callback argument is added to the API.

The LLIs should not be freed until the channel is de-configured
Hence, k_free of LLI memory is removed from stop handler.
Also, added code to disable the channel in stop handler.

Ulf Magnusson cc74397a17 drivers: dma: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

Andrew Boie 8345e5ebf0 syscalls: remove policy from handler checks
The various macros to do checks in system call handlers all
implictly would generate a kernel oops if a check failed.
This is undesirable for a few reasons:

* System call handlers that acquire resources in the handler
  have no good recourse for cleanup if a check fails.
* In some cases we may want to propagate a return value back
  to the caller instead of just killing the calling thread,
  even though the base API doesn't do these checks.

These macros now all return a value, if nonzero is returned
the check failed. K_OOPS() now wraps these calls to generate
a kernel oops.

At the moment, the policy for all APIs has not changed. They
still all oops upon a failed check/

The macros now use the Z_ notation for private APIs.

Adithya Baglody b0db28b512 drivers: Cmake: Add __ZEPHYR_SUPERVISOR__ macro for driver files.
Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.

In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.

Sebastian Bøe 12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make

header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Andrew Boie 0b474eef9c kernel: deprecate old init levels
PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.

New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Iván Briano d53811ec73 dma qmsi: Add support for device power management
Add the necessary infrastructure to support power management for the
QMSI DMA driver. If deep sleep is supported, this driver supports
saving its context to be restored on resume.

Iván Briano 0094ab228d ext qmsi: Update to QMSI 1.3 release
Update the QMSI drop we maintain in Zephyr, and fix the build where
needed:

- QM_SCSS_INT is renamed to QM_INTERRUPT_ROUTER;
- every member of QM_INTERRUPT_ROUTER was renamed as well;
- QM_IRQ_* renamed too, mostly added _INT at the end;
- some isr functions were renamed to keep their names consistent;
- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.

Jesus Sanchez-Palencia 5750354f7a dma: Fix QMSI shim by setting the DMA xfer type
Set DMA transfer to QM_DMA_TYPE_SINGLE for all channels.
This keeps the previous behavior as of QMSI 1.1.

In the future, we may consider adding support for using other DMA
transfer types. This, however, will demand adding new API to Zephyr's
dma.h .

Baohong Liu e965119cd9 dma: qmsi_shim: add typecasting to avoid compilation error
Add typecasting in dma QMSI shim to avoid compilation error.

The DMA API and QMSI have their own definitions for the
dma configuration parameters, such as handshake_interface,
handshake_polarity, source/destination_transfer_width,
channel_direction, and source/destination_burst_length.
When a API is called, the shim driver will assign values
for the above-mentioned parameters to the configuration
variable(based on QMSI's definiton) from the values in the
variable provided by the caller based on API's definition.
Even though all these parameters have similiar definition
and values in both the generic API and QMSI, QMSI uses
its own names which are different from those definied in
the generic API. Without typecasting, the parameter value
assignment will cause compilation error(even though error
only happens for some compiler).
