Updating the patch in the following way should make it possible to
support out-of-tree users while avoiding additional uses of 'isl':
- have two compatible entries in isl12057_dt_match struct instead of one
i.e.:
static const struct of_device_id isl12057_dt_match[] = {
{ .compatible = "isl,isl12057" },
{ .compatible = "isil,isl12057" },
{ },
};
I think it matches the situation we have.
- keeping the updates I had for trivial-devices.txt and
vendor-prefixes.txt files.
Thoughts?
Cheers,
a+
