* stm32: add stm32l431 ec in chip/stm32 : system / clock / timerBossen WU2021-06-301-455/+1637
| | | | | | | | | | | | | | stm32l431 related driver: system / clock / timer. The stm32l476g-eval is the only board which would be impacted.

* stm32l4: Refactor to use page instead of bank notationScott Collyer2020-08-311-5/+2
| | | | | | | | | | | | | | | | | | The L4 and G4 family share the same flash peripheral block. Therefore, the G4 can share the L4 driver. This CL adds macros which more closely track the TRM description of the flash module, especially w.r.t pages. There is no functional change for the L4 driver.

* stm32: Add known variants to registers filesCraig Hesling2019-07-171-0/+4
| | | | | | | | | | | | | | | | | | Although these registers files may support other variants, these listed variants are the only ones that are referenced throughout EC codebase. They were collected using the following grep line: grep -rIi 'variant.*stm32.'

| | | | | | | | | | | | | | | | | | | | | | | | | | | We enforce that all family specific registers file can only be included from registers.h.
