Linus, everyone,

during this short break of my holidays, I send the first pull request of
I2C for 5.10. Main changes:

* if a host can be a client, too, the I2C core can now use it to emulate
  SMBus HostNotify support (STM32 and R-Car added this so far)
* also for client mode, a testunit has been added. It can create rare
  situations on the bus, so host controllers can be tested
* a binding has been added to mark the bus as "single-master". This
  allows for better timeout detections
* new driver for Mellanox Bluefield
* massive refactoring of the Tegra driver
* EEPROMs recognized by the at24 driver can now have custom names
* rest is driver updates

Please pull.

Thanks,

   Wolfram
