commit e00c27ef3b4c23e39d0a77b7c8e5be44c28001c7
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.
However, The regulator information is based on an older temporary
pre-production board variant and does not reflect production board
750-2628-XXX boards.
LDO1 supplies VDDAPHY_CAM which is OMAP5's vdda_csiporta/b/c. This
can only be supplied at 1.5V or 1.8V and we currently supply 2.8V.
To prevent any potential device damage risk, use the specified
1.5V-1.8V supply.
Remove 'always-on' and 'boot-on' settings here as it is
a 'on need' supply to SoC IP and is not enabled by PMIC by
default at boot.
