soc: st: stm32wb0: support SoCs without SMPS output current limit (277504cf) · Commits · Wenxi XU / zephyr

The STM32WB06 and STM32WB07 SoCs do not support SMPS output current limit. This makes the LL_PWR_SetSMPSPrechargeLimitCurrent function and all the LL_PWR_SMPS_PRECH_LIMIT_CUR_xxx defines not visible when one of these SoCs is selected, resulting in a build failure. Fix this by only handling SMPS current limit when the feature is available. Signed-off-by:
