OK yeah sounds like they won't do anything currently.

OK I'll apply the following updated version of your patch later today.
I left out the links from the description and the timestamps too.

Subject: [PATCH] ARM: dts: omap5-board-common: Describe the voltage supply
mapping accurately
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
OMAP5uEVM based platforms share a similar voltage rail map. This
should be properly described in device tree, without this regulator core
will be unable to determine the source voltage of LDOs such as LDO9 and
SMPS10 which could be configured for bypass depending on the voltage
requested of them. This results in conditions such as:
ldo9: bypassed regulator has no supply!
ldo9: failed to get the current voltage(-517)
