|  | STMicroelectronics ST21NFCA core driver. It implements the chipset | 
|  | HCI logic and hooks into the NFC kernel APIs. Physical layers will | 
|  | register against it. | 
|  |  | 
|  | To compile this driver as a module, choose m here. The module will | 
|  | be called st21nfca. | 
|  | Say N if unsure. |

|  | This module adds support for the STMicroelectronics st21nfca i2c interface. | 
|  | Select this if your platform is using the i2c bus. | 
|  |  | 
|  | If you choose to build a module, it'll be called st21nfca_i2c. | 
|  | Say N if unsure. |
