On STM32WL, the backup memory is defined as part of the TAMP peripheral. This seems to be a deviation from the stm32 family where this memory is defined as part of the RTC. The STM32WL reference manual shows that tamp_pclk is connected to rtc_pclk. This means that the clock required to run the TAMP peripheral is the same as the RTC's. A quick port of BBRAM on STM32WL is achieved by instanciating the bbram device as a child of the RTC and by modifying the address offset to the first backup register from the rtc base address.
