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?

Yes go ahead if you want, an immutable branch based on v6.16-rc1
is the best for me, then I pull that in.

I could also just apply it and hope for the best... it usually works.

I have a rework of gpio-mmio in progress that removes the bgpio
specific fields from struct gpio_chip. This includes moving the flags
into a separate gpio/generic.h header. I really need to either apply
it myself or get an immutable tag from you with this change.
