Due to wrong older revision of documentation used as reference, we seem to have a bunch of LDOs wrongly configured on OMAP5 uEVM. This series is based power tree on production board 750-2628-XXX platform. Unfortunately, the wrong voltages may be detrimental to OMAP5 as they supply hardware blocks at voltages that are out of specification.
