Do you need to print this? The component helper is already fairly
verbose about what succeeds and fails.
Will remove.

I'd much rather you used the new matching support rather than using the
old .add_components. The new matching support is more efficient as you
only have to scan DT once, rather than each time we try to probe. That
will mean...
That is otherwise fine, but with the match code it not possible to
implement a master that may not have any components.
Would it be Ok to add a check that master->ops->add_components is
defined, before calling it in find_componets()
(drivers/base/component.c:120) and return 0 if it is not?
Best regards,
Jyri

You need to build a struct component_match array here using
component_match_add()...
- return drm_platform_init(&tilcdc_driver, pdev);
+ return component_master_add(&pdev->dev, &tilcdc_comp_ops);
and then finally register the ops with component_master_add_with_match().
Thanks.
