[PATCH 0/3] ASoC: cs42l42: Fix definition and handling of jack switch invert

[Richard Fitzgerald]

Summary: The driver applied the opposite of the DT setting to the
wrong register bit.

The jack plug detect hardware in cs42l42 is somewhat confusing,
compounded by an unclear description in the datasheet. This is most
likely the reason that the driver implemented a DT property for the
wrong register bit, that had the opposite effect of what was
described in the binding.

Changing the meaning of the property values isn't feasible; the
driver dates from 2016 and the risk of breaking out-of-tree configs
is too high (the property is also available to ACPI systems).

So the fix is to make the binding doc match the actual behaviour and
then fix the driver to apply it to the correct register bit.

As a bonus, patch #3 converts the binding to yaml.
