The i2c controllers on the P2040/P2041 have an erratum where the
documented scheme for i2c bus recovery will not work (A-004447). A
different mechanism is needed which is documented in the P2040 Chip
Errata Rev Q (latest available at the time of writing).

 From what I can tell this Erratum also applies to P1010

Will add for v3.

Also, I think this series should go to stable.

This series builds on changes that have been merged for v5.13. I haven't 
checked if it applies to stable, I think at least commit 65171b2df15e 
("i2c: mpc: Make use of i2c_recover_bus()") would need to come along 
with it.
