[PATCH 0/9] ARM: dts: omap5-uevm: fixup wrong regulator configuration

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.

based on v3.11-rc1 tag

git link: git://github.com/nmenon/linux-2.6-playground.git
branch: push/omap5-palmas-fixes

Tested with https://patchwork.kernel.org/patch/2545061/
 + https://git.kernel.org/cgit/linux/kernel/git/ssantosh/linux.git/log/?h=for_3.11/out_of_tree/omap5_clk_data
