Core driver for Samsung S3FWRN5 NFC chip. Contains core utilities
of chip. It's intended to be used by PHYs to avoid duplicating lots
of common code.

This module adds support for an I2C interface to the S3FWRN5 chip.
Select this if your platform is using the I2C bus.
To compile this driver as a module, choose m here. The module will
be called s3fwrn5_i2c.ko.
Say N if unsure.
