e8a91c953f [ARM] omap: Fix IO_ADDRESS() macros
OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies
for use with __raw_{read|write}* for accessing registers.  Therefore,
these macros should return (void __iomem *) cookies, not integer values.

Doing this improves typechecking, and means we can find those places
where, eg, DMA controllers are incorrectly given virtual addresses to
DMA to, or physical addresses are thrown through a virtual to physical
address translation.

542313cc98 ARM: OMAP2: Clock: Add OMAP3 DPLL autoidle functions
This patch adds support for DPLL autoidle control to the OMAP3 clock
framework.  These functions will be used by the noncore DPLL enable
and disable code - this is because, according to the CDP code, the
DPLL autoidle status must be saved and restored across DPLL
lock/bypass/off transitions.

N.B.: the CORE DPLL (DPLL3) has three autoidle mode options, rather
than just two.  This code currently does not support the third option,
low-power bypass autoidle.

a58caad113 ARM: OMAP: Introduce omap_globals and prcm access functions for multi-omap
New struct omap_globals contains the omap processor specific
module bases. Use omap_globals to set the various base addresses
to make detecting omap chip type simpler.

Also introduce OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS for future multi-omap
patches.

69d88a00a2 ARM: OMAP2: Add common register access for 24xx and 34xx
This patch adds common register access for 24xx and 34xx power
and clock management in order to share code between 24xx and 34xx.

Only change USB platform init code to use new register access, other
access will be changed in later patches.
