Subject: [RFC PATCH V2 6/8] ARM: dts: TWL6030/OMAP4: Add OMAP voltage path linkage

OMAP4430 and 4460 platforms use TWL6030 to power voltage rails.
However, on 4460, we use twl6030 only for iva and core voltage rails.

Introduce an twl6030_omap4.dtsi to be able to reuse the base definition
for all OMAP4 platforms and the delta change only for panda-es platform
which is based on 4460.

Signed-off-by: Nishanth Menon <nm@...com>
