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.
