patch #1 ARM: dts: omap5-uevm: document regulator signals used on the 
actual board
   -> as is, since it is a documentation patch
Patch #2: ARM: dts: omap5-uevm: fix regulator configurations mandatory 
for SoC
squash of:
-> ARM: dts: omap5-uevm: update LDO1 voltage to 1.5V and settings
-> ARM: dts: omap5-uevm: update LDO3 voltage to 1.5V and settings
-> ARM: dts: omap5-uevm: update LDO4 voltage to 1.5V and settings
-> ARM: dts: omap5-uevm: update LDO6 voltage to 1.2V
-> ARM: dts: omap5-uevm: update LDO7 voltage to 2V and settings
-> ARM: dts: omap5-uevm: update SDCARD LDO9 and resource REGEN3

Patch #3: ARM: dts: omap5-uevm: update optional regulator configurations
squash of:
  -> ARM: dts: omap5-uevm: update SMPS9 settings
  -> ARM: dts: omap5-uevm: update and disable unused regulators LDO[28]

Does that sound fine?
