kconfig: Fix up newly-introduced copy-pasted headers Same deal as in https://github.com/zephyrproject-rtos/zephyr/pull/20280, for newly-introduced stuff. Will avoid failures with the new CI test in https://github.com/zephyrproject-rtos/ci-tools/pull/112, though it only checks changed files. Also fix some un-indented properties on choices. Choice properties work the same as symbol properties syntactically. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

This module implements a kernel device driver for the LowPower Timer
and provides the standard "system clock driver" interfaces.

prompt "LPTIM clock value configuration"
drivers: timer: stm32: Use dt to configure LPTIM domain clock Instead of relying on Kconfig, use dt inputs to configure LPTIM domain clck (LSI/lSE). Clock control dedicated APIs are used for configuration and get the frequency of domain clock in use. Constants macros used previously to store frequency and time base are converted to static global variables. Some code was set up specifically to keep compatibility with targets that still use Kconfig to configure domain clock. This will be removed after a deprecation period.

This option is deprecated and configuration of LPTIM domain clock
using devicetree should be preferred.

Use LSI as LPTIM clock
drivers/timers: stm32_lptim: Set LSI as default LPTIM clck source Timer STM32 LPTIM currently supports 2 clocks sources: LSE & LSI. LSE (external) is defined as default but its availability depends on board support package and then may not be available. This ends up in situations where users have LSE implicitly selected while no crystal is available on board, leading to non functional LPTIM. To avoid this situation, makes LSI clock, which is always available (since internal to the SoC), the default LPTIM source clock. Then, default case will be functional. Users will then be able to select LSE if needed. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

drivers: timer: stm32_lptim: Change clock source config check sanction A specific check is implemented lptim driver in order to ensure global platform clock/tick configuration is in line with recommendations. To respect portability principles, don't error out when a config conflict is detected but generates a warning instead. Also, since these are only recommendations, provide an option to override the check. Besides automatically override when ZTEST is enabled, as some kernel tests specifically configure tick freq to 100. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

For LPTIM configuration, a specific tick freq is advised
depending on LPTIM input clock:
- LSI(32KHz): 4000 ticks/sec
- LSE(32678): 4096 ticks/sec
To prevent misconfigurations, a dedicated check is implemented
in the driver.
This options allows to override this check
