[0/3] SAMA5D2 i2c bus recovery testing

Message

Here are the sama5d2 patches, as there is not pinmux defined in the
dtsi. I choosed to only apply it to derivated board as the i2c
configuration is specific for each.

Of course, it could be great if could test it on the ptc board as well.

Best Regards,
Kamel

The i2c mailing list is missing, can you resend it please.

By the way, it fails to apply against next and 5.5-rc1. On which version is it
based? I assume a cherry-pick should work but git am fails.

Actually it was not intended to be sent to any mailing list, it is a
mail for Codrin so he can achieve some tests.

It's based on 5.4, Im not sure it will apply on next but it should on
5.5, anyway it is a WIP here.
