[PATCH 0/5] stm32-ddr-pmu driver creation

From: Gerald BAEZA
Date: Mon Apr 29 2019 - 06:04:23 EST


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

This series depends on the "clk: stm32mp1: Add ddrperfm clock" patch,
sent separately.
