[PATCH v5 1/5] ARM: dts: imx6qdl-icore: Add Sound card support

Jagan Teki
2017-09-18T11:36:09Z

Linux Sound card now uses generic simple-audio-card, so add
the same along with related audmux and codec(via u2c3) for
i.CoreM6 QDL module boards.

Changes for v5:
- Add adumux
- Update simple-audio-card,widgets
- Add ssi1 fsl,mode
- Add #sound-dai-cells in codec
Changes for v4:
- Moved sgtl5000 node into dtsi instead of multiple copies of
same in dts files
Changes for v3:
- Replace fsl,imx-audio-sgtl5000 and use simple-audio-card
Changes for v2:
- Use proper [label:] node-name[@unit-address] for codec
