[PATCH v3 0/7] Turris Omnia MCU driver

[PATCH v3 0/7] Turris Omnia MCU driver

[Marek Behún]

Hello Andy, Linus, Arnd, Gregory, and others,

this is v3 of series adding support for Turris Omnia MCU. See the cover
letter from v1 and v2:
  https://patchwork.kernel.org/project/linux-soc/cover/20230823161012.6986-1-kabel@kernel.org/
  https://patchwork.kernel.org/project/linux-soc/cover/20230919103815.16818-1-kabel@kernel.org/

Changes since v2:
- I've dropped the usage of devm_device_add_group(), since it is
  deprecated as noted by Andy. In patch 4 I use the .is_visible()
  attribute group method instead
- dropped the setting of min_hw_heartbeat_ms watchdog member in 5/7,
  since it is not needed, as suggested by Guenter
- addressed Linus' and Andy's suggestions in patches 2/7 and 3/7.
  There is one of Andy's suggestions which I did not address completely,
  see changelog directly in patch 3/7
