Subject[PATCH v3 0/5] stm32-ddr-pmu driver creation
Date
The DDRPERFM is the DDR Performance Monitor embedded in STM32MP1 SOC.

This series adds support for the DDRPERFM via a new stm32-ddr-pmu driver,
registered into the perf framework.

This driver is inspired from arch/arm/mm/cache-l2x0-pmu.c

---
Changes from v1:
- add 'resets' description (bindings) and using (driver). Thanks Rob.
- rebase on 5.2-rc1 (that includes the ddrperfm clock control patch).

Changes from v2:
- rebase on 5.3-rc6 that has to be completed with
'perf tools: fix alignment trap in perf stat': mandatory.
'Documentation: add link to stm32mp157 docs': referenced from this series.
- take into account all remarks from Mark Rutland: thanks for your time!

- fix for event type filtering in stm32_ddr_pmu_event_init()
