Ioannis Glaropoulos ccf90fd9c2 soc: arm: select CPU_HAS_SYSTICK in ARCH Kconfig
ARM SysTick timer is implemented by default in ARMv7-M
and Mainline ARMv8-M processors, so we include the
corresponding Kconfig symbol in arch/arm/core/cortex-M/Kconfig
and remove the selections from the Cortex-M SOCs.

Anas Nashif 3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier
Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier.  Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

Piotr Mienkowski 204311d004 power: rename Low Power States to Sleep States
There exists SoCs, e.g. STM32L4, where one of the low power modes
reduces CPU frequency and supply voltage but does not stop the CPU. Such
power modes are currently not supported by Zephyr.

To facilitate adding support for such class of power modes in the future
and to ensure the naming convention makes it clear that the currently
supported power modes stop the CPU this commit renames Low Power States
to Slep States and updates the documentation.

Piotr Mienkowski f04a4c9deb power: rename CPU_LPS_n power states
CPU_LPS_n name used to indicate a low power state is cryptic and
incorrect. The low power states act on the whole SoC and not exclusively
on the CPU. This patch renames CPU_LPS_n states to LOW_POWER_n. Also
HAS_ pattern for Kconfig options is used in favor of a non standard
_SUPPORTED. Naming of deep sleep states was adjusted accordingly.

Following is a detailed list of string replacements used:
s/SYS_POWER_STATE_CPU_LPS_(\d)_SUPPORTED/HAS_STATE_LOW_POWER_$1/
s/SYS_POWER_STATE_CPU_LPS_(\d)/SYS_POWER_STATE_LOW_POWER_$1/

This commit removes dependency on SYS_POWER_LOW_POWER_STATES_SUPPORTED,
SYS_POWER_DEEP_SLEEP_STATES_SUPPORTED Kconfig options. Power management
SYS_POWER_LOW_POWER_STATES, SYS_POWER_DEEP_SLEEP_STATES options depend
now directly on specific power states supported by the given SoC. This

Piotr Mienkowski 893a7b7af0 soc: silabs: add support for setting low power states
This commit adds sys_set_power_state() function with support for EM1
Sleep, EM2 Deep Sleep, EM3 Stop power modes on Silabs SoCs.

Tested on efr32_slwstk6061a board.

Note: No support for efm32hg, efm32wg series at this point due to the
missing possibility of placing function code in RAM, required by errata
in SiLabs library code.

Piotr Mienkowski 973af2c8d7 dts: silabs: use 'aliases' to remove dts_fixup defines
By adding 'aliases' node in SoC .dtsi file it is possible to generate
DT_ defines which specify a logical name rather than relay on module
location on APB bus. E.g. DT_SILABS_GECKO_USART_40010000_LABEL becomes
DT_SILABS_GECKO_USART_USART_0_LABEL. Thus it is possible to remove
dts_fixup.h defines.

Piotr Mienkowski ab748e3afb soc: silabs_exx32: remove pinmap dependency on part number
Within a single series pin mapping between location setting and pin name
is uniform. The only difference is availability of the module, i.e. i2c1
may be missing on some part numbers, or availability of the pin, i.e.
32 pin package will not provide all the pins available on 48 pin
package. It's better to manage these differences at the DTS/Kconfig
level.

This commit removes dependency of soc_pinmap.h files on part numbers.

Ulf Magnusson 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.

Search for "Kconfig.defconfig" in
https://docs.zephyrproject.org/latest/application/kconfig-tips.html for
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
 - ALTERA_AVALON_SYSID
 - CLOCK_CONTROL_IMX_CCM
 - CPU_EM4_DMIPS
 - CPU_EM4_FPUDA
 - CPU_EM4_FPUS
 - FP_FPU_DA
 - I2C_GECKO

Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Sebastian Bøe 8eb734cd82 DT: Rename from dts.fixup to dts_fixup.h
The Zephyr configuration system uses many different files in many
different formats. It makes it a lot easier for users to understand
what these files do if when we use the correct file extensions.

To this end we rename the dts.fixup files to the correct file
extension '.h'.

This is a breaking change for out-of-tree fixup files. Such files will
be detected and given an appropriate error message.
