-From: Fe-Pi <fe-pi@cox.net>
-Date: Wed, 1 Mar 2017 04:42:43 -0700
-Subject: [PATCH] Add support for Fe-Pi audio sound card. (#1867)
-
-Fe-Pi Audio Sound Card is based on NXP SGTL5000 codec.
-Mechanical specification of the board is the same the Raspberry Pi Zero.
-3.5mm jacks for Headphone/Mic, Line In, and Line Out.
