OMAP: ID: introduce chip detection for OMAP4460
Add support for detecting the latest in the OMAP4 family: OMAP4460
Among other changes, the new chip also can support 1.5GHz A9s,
1080p stereoscopic 3D and 12 MP stereo (dual camera). In addition,
we have changes to OPPs supported, clock tree etc, hence having a
chip detection is required.
For more details on OMAP4460, see Highlights:
