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

[PATCH v4 2/6] ARM: dts: imx6qdl-icore-rqs: Move Sound nodes to dtsi

[Jagan Teki]

From: Jagan Teki <jagan@amarulasolutions.com>

imx6q, imx6dl icore-rqs modules share common sound nodes,
so move the sound nodes from imx6q-icore-rqs into dtsi so-that
both can share the common node details.

And also replace codec: sgtl5000@0a => sgtl5000: codec@a
on imx6q-icore-rqs.dts to [label:] node-name[@unit-address]
according to devicetree specification from ePAPER v1.1

Please add the support of this panel to drivers/gpu/drm/panel/panel-simple.c.

Then you can refer its compatible in your board dts.

Does the existing ampire,am800480r3tmqwa1h binding work for your display?

Yes, it is working..but need to understand how these respective
timings were calculated(because I need to add few more) . I tried this
supported ampire but couldn't get the data-sheet. Please point me if
you find any details.
