[PATCH v3 4/5] OMAP: mailbox: build device using omap_device/omap_hwmod

[Omar Ramirez Luna]

From: Felipe Contreras <felipe.contreras at gmail.com>

Remove static platform_device and resource data within
omap mailbox driver; use the one defined in the hwmod
database along with omap_device framework for device
build and registration.
