From e4981de3c02a5d73085ba036be4e104a6b034791 Mon Sep 17 00:00:00 2001 From: Matt Flax Date: Tue, 28 Aug 2018 18:42:13 +1000 Subject: [PATCH 411/454] 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.
