This is a series of patches fixing several bugs and implementing
new features.

Bug fixes:
1) Fix the frequency calculation
2) Fix incorrect base address passed during io write
3) prevent stack overflow in mlxbf_i2c_smbus_start_transaction()
4) Support lock mechanism to avoid race condition between entities
   using the i2c bus

Cleanup:
5) remove IRQF_ONESHOT flag as it is no longer needed.

Features:
6) Update SPDX license
7) Support multi slave functionality
8) Support BlueField-3 SoC
9) Update binding devicetree

What has changed from v1->v2:
- moved all the bug fixes to the top commits and left the features for last
- split the BlueField-3 SoC patch into 2: one for the driver code and another
  patch for the device tree binding yaml documentation file
- keep the device tree/acpi tables backward compatible. So add the new resources at the
  end of the enum.
- update the license in a separate patch

In v3, updated the cover letter to reflect changes made from v1->v2 and add Rev-by
