Updated patch below, then signing it off to you guys :)

Oops right if the pins 4 - 8 are not connected, no aux regulator
is needed.

OK updated that too below.
I've kept your Ack as the changes were minor. If no other
comments, I will apply this into omap-for-v3.14/dt probably
on Thursday.

Subject: [PATCH] ARM: dts: Add support for sbc-3xxx with cm-t3730
This adds support for CompuLab SBC-T3530, also known as cm-t3730:
http://compulab.co.il/products/sbcs/sbc-t3530/
It seems that with the sbc-3xxx mainboard is also used on
SBC-T3517 and SBC-T3730 with just a different CPU module:
http://compulab.co.il/products/sbcs/sbc-t3517/
http://compulab.co.il/products/sbcs/sbc-t3730/
So let's add a common omap3-sb-t35.dtsi and then separate SoC
specific omap3-sbc-t3730.dts, omap3-sbc-t3530.dts and
omap3-sbc-t3517.dts.
I've tested this with SBC-T3730 as that's the only one I have.
At least serial, both Ethernet controllers, MMC, and wl12xx WLAN
work.
Note that WLAN seems to be different for SBC-T3530. And SBC-T3517
may need some changes for the EMAC Ethernet if that's used
instead of the smsc911x.
