Hello Arnd, Gregorgy and others,

this is v2 of series adding support for Turris Omnia MCU. See the cover
letter from v1:
  https://patchwork.kernel.org/project/linux-soc/cover/20230823161012.6986-1-kabel@kernel.org/

I am also sending this to specific subsystem maintainers as requested by
Krzysztof.

Changes since v1:
- incorporated small changes requested by Krzysztof Kozlowski
- in order to make reviewing simpler, I split the second patch, which
  implements the MCU driver, into four incremental patches:
  - patch 2/7 adds basic driver skeleton
  - patch 3/7 adds GPIO support
  - patch 4/7 adds board poweroff and wakeup support
  - patch 5/7 adds MCU watchdog support

Marek
