Mention changes to kconfig options PM_S2RAM and PM_S2RAM_CUSTOM_MARKING and how to migrate to adhere to the changes which affect the nRF54H20. Signed-off-by: Bjarki Arge Andreasen <[email protected]>
Currently it is possible to have an enabled (status="okay") "suspend-to-ram" "zephyr,power-state" in the devicetree, CONFIG_PM=y, but CONFIG_PM_S2RAM=n This means the presence and state of the "suspend-to-ram" power state in the devicetree does not match the PM_S2RAM option, despite PM_S2RAM being dependent on the devicetree state. This commit makes the devicetree the "source of truth" for whether one or more s2ram power states shall be included and supported, by enabling PM_S2RAM if any s2ram power state with status "okay" is present in the devicetree. To disable the s2ram power state, like with any other state, disable it by setting its state to "disabled". The help of the now promptless PM_S2RAM config has been updated to reflect the new meaning. It previously held cortex-m specific implementation details, these have been removed as these details are already present in the file pointed to as well (arch/arm/core/cortex_m/pm_s2ram.c line 22) Signed-off-by: Bjarki Arge Andreasen <[email protected]> (cherry picked from commit 4626f6b)
…ptless The config PM_S2RAM_CUSTOM_MARKING is not an optional config for a user to select, it is required by some soc implementations of S2RAM, in which case it must be selected by the soc. Refactor the configuration to be HAS_PM_S2RAM_CUSTOM_MARKING, and make the currently only soc which needs it select it. Then update samples which previously had to select this option for this soc. Signed-off-by: Bjarki Arge Andreasen <[email protected]> (cherry picked from commit 1767f13)
This commit adds support using pm_s2ram for 54H when the MPU is disabled. This is the case for the out of tree sample `sdk-nrf/samples/nrf54h/empty_app_core`. Without this commit the linker will fail to link `z_arm_mpu_init` and `z_arm_configure_static_mpu_regions`. Signed-off-by: Rubin Gerritsen <[email protected]> (cherry picked from commit 05b77ec)
On nrf54h20 only cpuapp supports s2ram low power cpu state. Signed-off-by: Sebastian Głąb <[email protected]> (cherry picked from commit 6ec763474f6593ceafe70f79731247ede3721984)
