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.

Patches 1-4 and 5-9 can go upstream independently. I suggest taking
patch 1/9 through the GPIO tree and providing an immutable tag to
Linus to take patches 2-4 through the pinctrl tree. Linus: are you OK
with that?
