[PULL REQUEST] i2c for v5.15

[Wolfram Sang <wsa@kernel.org>]

[-- Attachment #1: Type: text/plain, Size: 5585 bytes --]

Linus,

I2C has a smaller pull reuest this time:

* new driver for I2C virtio
* removal of PMC SMP driver because platform is already gone
* IRQ probing and DMAENGINE API cleanups
* add SI metric prefix definitions to units.h
* beginning of i801 refactorization
* a few driver improvements

linux-next had trivial merge conflicts for
include/uapi/linux/virtio_ids.h and include/linux/units.h. The fixes
from Stephen were correct.

Please pull.

Thanks,

   Wolfram
