Subject: [PATCH v6 00/11] Turris Omnia MCU driver

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

I am sending v6 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/

See the cover letters for v1, v2, v3, v4 and v5:
  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/

  https://patchwork.kernel.org/project/linux-soc/cover/20231026161803.16750-1-kabel@kernel.org/
  https://patchwork.kernel.org/project/linux-soc/cover/20240323164359.21642-1-kabel@kernel.org/

Changes since v5:
- use dev_get_drvdata(dev) instead of
  i2c_get_clientdata(to_i2c_client(dev))
- uses devm_mutex_init() from the above mentioned branch
- addressed Andy's suggestions for patch 2 (excluding the one suggesting
  100 column lines, I still prefer 80 columns)
- addressed Dan's suggestion for devm_irq_create_mapping() (return
  -ENXIO if mapping could not be created, not 0 as irq_create_mapping()
  does)
- I threw away the changes for other drivers that came with the new
  devm_ helpers, notably conversion to devm_debugfs_create_dir(), as
  there were some problems
