This patch series introduces the Hardware Debug Port (HDP) support for STM32MP platforms. It includes updates to the mmio gpio driver, the addition of device tree bindings, the HDP driver, 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 HDP driver and adds the necessary pinmux configurations for HDP pins on STM32MP157C-DK2 as example.
