Subject: [PATCH] ARM: dts: imx7d: add missing OPP property for cpu0

Commit b97872d4eb22 ("ARM: dts: imx: Add missing OPP properties for CPUs")
added "operating-points" property for all CPUs, but missed i.MX7D's cpu0,
this patch adds it.

In general, when you send a patch fixing a commit, you should have the
author of that commit copied. I added Viresh here.

It looks like a wrong fix to me. It seems that commit b97872d4eb22
shouldn't change imx7d.dtsi at all. So the correct fix would be
reverting the change on imx7d.dtsi, @Viresh?

Please just send a incremental fix patch for that commit.

Sure. Actually I almost wrote the patch but then realized that it
wouldn't be fair for me to send a patch for something Anson has been
working on.

@Anson: Please send a patch to remove the "operating-points" property.

Agreed, I think the arch/arm/boot/dts/imx7d.dtsi should NOT be changed, as it already
had operating-points-v2 on both CPUs, I sent out another new patch with correct fix,
please review it.

Thanks.

Anson.
