   4 Subject: [PATCH 163/782] Add support for audioinjector.net ultra soundcard.
   5  (#2664)
   6
   7 Uses the simple-audio-card ALSA machine driver. Sets up the machine
   8 driver in the device tree overlay file. The overlays/Makefile is
   9 altered to add the audioinjector-ultra.dtbo dtb overlay.
  10
  11 Adds CONFIG_SND_SOC_CS4265 to the defconfig files.
