Hello Andy, Hans, Ilpo, Arnd, Gregory, and others,

this is v8 of the series adding Turris Omnia MCU driver.

This series depends on the immutable branch between LEDs and locking,
introducing devm_mutex_init(), see the PR
  https://lore.kernel.org/linux-leds/20240412084616.GR2399047@google.com/

Changes since v7:
- fixed wrong $id path in DT binding (patch 1)
- removed resource managed IRQ mapping disposal, which is not needed, as
  pointed out by Andy (patches 6, 7)
- added some more #includes (for linux/device.h, linux/interrupt.h,
  linux/hw_random.h) (patches 3, 6, 7)
- dropped the Fixes tags from the DT changes (patches 8, 9), with an
  explanation of this added into the commit message of patch 8, as
  suggested by Andrew
