-Subject: [PATCH] BCM270X: Adding device tree support for AudioSense-Pi
- add-on soundcard
-
-Device tree overlay for AudioSense-Pi card.
-
-To enable support for the hardware add the following
-line to the RPi /boot/config.txt:
-
-	dtoverlay=audiosense-pi
-
-More documentation @ arch/arm/boot/dts/overlays/README
