CORTEX_M_SYSTICK should be disabled if LPTIM is selected.
Current implementation is not efficient to do so.

29f4574052 dts/arm: stm32: Don't disable systick
In some stm32 series systick was disabled in order to
allow alternate use of lptim timer as kernel low power ticker.
Doing this, dts based definition of CORTEX_M_SYSTICK Kconfig symbol
is disabled and CORTEX_M_SYSTICK was redefined with 'default y'
in stm32 soc files which makes things more complex to handle to
alternate with LPTIM activation.

e671d363b8 drivers: memc: stm32: initial support for stm32 FMC
This commit adds a new driver category for memory controller
peripherals. There is no API involved for now, as it has not been found
necessary for first implementation.

STM32 Flexible Memory Controller (FMC) is the only controller supported
for now. This peripheral allows to access multiple types of external
memories, e.g. SDRAM, NAND, NOR Flash...

The initial implementation adds support for the SDRAM controller only.
The HAL API is used, so the implementation should be portable to other
STM32 series. It has only been tested on H7 series, so for now it can
only be enabled when working on H7.

Linker facilities have also been added in order to allow applications to
easily define a variable in SDRAM.

a42a42cd5a kconfig: Replace defconfig singe-symbol 'if's with 'depends on'
Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.

Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.

Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

3a95dda66c drivers/eeprom: stm32: Enables only for L1 series
Setting EEPROM_STM32 with `default y` under `if SOC_FAMILY_STM32`
overrides `depends on SOC_SERIES_STM32L1X` in EEPROM_STM32
definition.
Then, if ever EEPROM is set in any file (as in
tests/drivers/build_all`), EEPROM_STM32 will be indeed set,
with potential issues on series where driver is not yet correctly
handled.

Fix this by removing EEPROM_STM32 definition in STM32 generic
file and set `default y` along with the `depends on` to keep
it effective.

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.

bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

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.

7c7db00a77 drivers: adc: add driver support for ADC1 of stm32
This commit adds driver support for ADC1 on all 8 supported series of
stm32 with resolution and conversion time selection and calibration.

Currently DMA is not supported for all series, and without it, zephyr
won't be able to catch up ADC's end of conversion interrupt, so this
version of the driver supports one channel conversion only. Users want
multi-channel conversion should use multiple sequences in their app
code.

This driver uses LL lib rather than HAL because the current HAL lib for
ADC will call HAL_DMA_* functions rather than using zephyr's common DMA
interface, so that way the driver will break the consistency of the
code.

This driver has been tested on multiple nucleo boards including
NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/F746ZG/L073RZ/L476RG and all
passed the test cases in tests/drivers/adc/adc_api. If the external ADC
line is floating, it may fail the tests since ADC may get 0V and the
test cases think 0 is failing. Connect it to any voltage source between
0-3.3V will help passing the test cases.

4638652214 Kconfig: Use 'default' instead of 'def_bool' in Kconfig.defconfig files
This can help find unused symbols. Those end up without a type if
'default' is used instead of 'def_bool', which generates a warning.

a longer explanation.

Keep the 'def_bool' for the following symbols, which seem to be
deliberately defined only in Kconfig.defconfig files:

 - ALTERA_AVALON_I2C
 - ALTERA_AVALON_MSGDMA
 - ALTERA_AVALON_PIO
 - ALTERA_AVALON_QSPI
