OMAP1: PM: update and decouple from OMAP2/3 PM core
Browse files Browse the repository at this point in the history 
Update OMAP1-specific PM infrastructure.  This is a sync of what is in
linux-omap for OMAP1.

This mostly de-couples OMAP1 PM from OMAP2/3 PM and renames things
accordingly, and removes omap2/3 specific code from OMAP1 specific
headers.

Original OMAP1 decoupling patch for OMAP PM branch by Paul Walmsley.
