Sure, please do it, why not, it is quite a safe modification.

One change per one dtsi file will suffice, and I see that imx25.dtsi
already contains the requested change, however probably you may
want to update its compatible = "fsl,imx25-epit" line.

Regarding compatibles for other imx6* SoCs, I think all of them should
be documented in fsl,imxepit.txt and then added to the correspondent
dtsi files one per SoC.

And I forgot the outcome of one former discussion with Uwe Kleine-König,
but if my bad memory serves me, we agreed that i.MX25 was released later
than i.MX31, so the most generic (the last value in the list) compatible
should be a compatible with i.MX31 like in

	imx25.dtsi:367:	compatible = "fsl,imx25-gpt", "fsl,imx31-gpt";

With best wishes,
Vladimir
