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 >-----Original Message----- >From: Marcel Holtmann [mailto:marcel@xxxxxxxxxxxx] >Sent: Tuesday, May 02, 2017 12:29 PM >To: Shikha SINGH <shikha.singh@xxxxxx> >Cc: Samuel Ortiz <sameo@xxxxxxxxxxxxxxx>; linux-wireless <linux- >wireless@xxxxxxxxxxxxxxx>; linux-nfc@xxxxxxxxxxxx; Manoj KUMAR ><manoj.kumar@xxxxxx>; Sylvain FIDELIS <sylvain.fidelis@xxxxxx>; Raphael >COLLADO <Raphael.COLLADO@xxxxxx>; MMS_MMY_Applications_SW ><MMS_MMY_Applications_SW@xxxxxxxxxxx>; Rob Herring ><robh@xxxxxxxxxx> >Subject: Re: [linux-nfc] [[PATCH v1] 0/6] Support of ST NFC Transceiver > >Hi Shikha, > >> *** V1.0 *** >> This patch series is generated on top of latest code available on >> nfc-next. >> >> This patch series introduces the following features: >> >> (a) A generic Digital NFC UART framework. >> The framework itself is an LDISC registered with the tty core.
