Hello Marcel,
          Thanks for making me aware of this new concept of serdev.

Samuel,
	You can pick my release selectively only for SPI interface.

You can skip below 2 patches which were only for UART support -
Patch#1 : A generic Digital NFC UART framework.
Patch#3 : An ST NFC UART LDisc driver ...

 I will make new release for UART support based on serdev.

Thanks & Regards,
Shikha
