+From e2516e3a7d2244f74c3267be8bdc143448c278be Mon Sep 17 00:00:00 2001
+From: Matt Flax <flatmax@flatmax.org>

+Subject: [PATCH] Add support for audioinjector.net ultra soundcard.
+ (#2664)
+
+Uses the simple-audio-card ALSA machine driver. Sets up the machine
+driver in the device tree overlay file. The overlays/Makefile is
+altered to add the audioinjector-ultra.dtbo dtb overlay.
+
+Adds CONFIG_SND_SOC_CS4265 to the defconfig files.
