I'm not sure if naming the compatible as it is currently is correct.
The specific thing about this IC seems to be that it's flashed with
samsung-made firmware, so I need to confirm that:
- we don't want to match compatible with the IC name (the same IC may
be shipped with different fw on other devices)
- maintainers wouldn't want us to merge it with some other driver

Best regards,
Ivaylo
