Hello Andy, Hans, Ilpo, Arnd, Gregory, and others,
this is v11 of the series adding Turris Omnia MCU driver.
Changes since v10:
- dropped patch 7 from v10 ("Add support for digital message signing via
debugfs"). This must be done via different kernel API (should be
doable via keyctl), but this requires more work which I currently
don't have, unfortunately
- in patch 3 where I introduce support for MCU connected GPIOs
changed u32 types to unsigned long where it made sense, in order
to be able to use __assign_bit(), __set_bit(), test_bit().
This was suggested by Andy.
- in patch 3 deduplicated code in omnia_gpio_get_multiple()
- moved the "fixing" in patch 3 of functions introduced in patch 2
to patch 2, this was a rebasing error in v10
- changed date to September 2024 and KernelVersion to 6.11 in
Documentation/ABI/testing/sysfs-bus-i2c-devices-turris-omnia-mcu
