I can't do much more than thinking though. I have no clue how to change the voltages and compile the board files on order to test it with my SD Card.
I can set up the environment on your server where you can build your own device tree (.dtb) files if you like. Changing the voltages is as easy as editing operating-points entry in arch/arm/boot/dts/omap5.dtsi .
Just if someone reading this list wants to try on local computer, it is (assuming some ARM gcc):
git clone http://git.goldelico.com/gta04-kernel.git cd gta04-kernel git checkout letux-4.9-rc4
vi arch/arm/boot/dts/omap5.dtsi
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- letux_defconfig uImage LOADADDR=0x80008000 dtbs INSTALL_MOD_PATH=/tmp/kernel-modules-$$ modules modules_install cp arch/arm/boot/uImage modules arch/arm/boot/dts/omap*.dtb /mount/sdcard/boot/
or simplified for DT only
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- letux_defconfig LOADADDR=0x80008000 dtbs cp arch/arm/boot/dts/omap5*.dtb /mount/sdcard/boot/
