This patch series introduces the DDR Performance Monitor (DDRPERFM) support for
STM32MP platforms.
The series firstly improves the STM32MP25 RCC driver to make it usable
as an access controller, needed for driver probe.
It also includes the addition of device tree bindings, the HDP driver,
documentation and updates to the device tree files for
STM32MP13, STM32MP15 and STM32MP25 SoCs.
The series also updates the MAINTAINERS file to include myself as the
maintainer for the STM32 DDR PMU driver.
