[PATCH] arm: omap5: dts: split SMPS10 dt node

SMPS10 has two outputs OUT1 and OUT2. Hence SMPS10 is modeled as
two regulators. The dt node is split to reflect it.

Mmm, I'm curious. How is it supposed to work?

Do you have dedicated control on each output?

Otherwise, it should be seen as one output with two potential consumers.

Yes. It can be controlled by setting different values to the same bit fields.
You can refer [1] where we actually implement SMPS10 as two different regulators.

Great, thanks.

Can we merge that one safely if the driver changed are not done yet?

I think it shouldn't cause any issues. However Mark has already merged the
driver changes.

Thanks

Cool. I've just applied your patch in for_3.12/dts
