Beside that I received just 1/4 of v2. LKML has one as well:
https://lore.kernel.org/lkml/1606737627-29485-1-git-send-email-bongsu.jeon(a)samsung.com/

Where are the others?

Since S3FWRN82 NFC Chip, The UART interface can be used.
S3FWRN82 supports I2C and UART interface.

Changes in v2:
 -change the compatible name.
 -change the const to enum for compatible.
