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.

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. [1] -> http://permalink.gmane.org/gmane.linux.kernel/1542521 Thanks Kishon -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

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.

SMPS10 has two outputs OUT1 and OUT2. Hence SMPS10 is modeled as two regulators. The dt node is split to reflect it. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> --- arch/arm/boot/dts/omap5-uevm.dts | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-)
