[PATCHv2,3/5] ARM: dts: OMAP2+: Add mailbox nodes

Commit Message

Suman Anna July 22, 2013, 9:26 p.m. UTC

The mailbox DT node data has been added for OMAP2420,
OMAP2430, OMAP3430/OMAP3630, OMAP44xx devices. Data
for OMAP5 and other SoCs will be added separately.

The mailbox static device initialization logic is also
adjusted for a DT boot.
