The P2040/P2041 has an erratum where the i2c recovery scheme documented in the reference manual (and currently implemented in the i2c-mpc.c driver) does not work. The errata document provides an alternative that does work. This series implements that alternative and uses a property in the devicetree to decide when the alternative mechanism is needed.The series looks good to me. Usually, I don't take DTS patches. This time I'd make an exception and apply all patches to for-current because this is clearly a bugfix. For that, I'd need an ack from PPC maintainers. Could I have those for patches 2+3?
Yep, done. cheers
