Thanks for the patch.

This does not look like passing the schema validation. Please run
dtbs_check. The node names should use hyphens and end with "grp"
suffix. This remark applies to other cases below.

dtbs_check reports a lot of errors originating from imx6sll.dtsi and
friends. But nothing added by me. But yes, node names should use
hyphens, that is documented. I will fix that.

But having -grp at the end for these things with a frequency in the
name is uncommon.

I was fixing primarily arm64 boards and did not touch that many of armv7:
grep -R :.*100mhz.*grp arch/arm64/boot/dts/freescale/* | wc -l
46
